The UK’s Best Porcelain Sealer – 5 Top Matt & Polished Sealants

Sealing Porcelain slabs is just like sealing any other expensive patio stone or indoor tile. It’s possible to seal and protect your investment long term while it’s also possible to ruin your gorgeous patio or indoor area.

Paving Sealers are cheap and straightforward at the low end of the budget and stone specific at the high end. If you are serious about sealing your Porcelain stone, then you’ll want to use the best porcelain sealer on the market, or at least the best sealer you can afford.

Our Expertise

We have been sealing Porcelain paving slabs for over a decade; after Indian stone sealants, Porcelain is the next most popular high-end patio sealing project we undertake.

Getting the sealing process right every time requires you to choose a good porcelain sealer and have sound knowledge of what you are trying to do.

Below we will take you through a list of the best porcelain sealers we recommend you use that can be easily purchased online or at some local builders merchants. We will also give you brief guidance on how and where porcelain sealing can go wrong.

Let’s get started.

#1. Best Matt Look Porcelain Sealer – Stonecare4u

Stonecare4u’s Essential All Stone Sealer is pretty impressive; if you prefer a matt look for your ceramic and porcelain tile, this product promises to offer all-weather protection for any porcelain tile surface.

Among the leading matt look tile sealers on the market, it’s a 25litre product, which means that unless you have a car park-sized patio, this should be more than enough to do the job. With coverage of 4 – 6 metres per litre, this one purchase will stretch up to 150sq / metres.

The application can be completed with a roller/paintbrush, but I’d use a low-pressure sprayer if the area is big. Otherwise, you can expect a bad back. It has inbuilt super water repellence, which means it can handle harsh weather conditions.

Once sealed, you can expect to see little droplets of rainwater all over the patio as it’s no longer able to impregnate the stone. It’s pricey, but this is the one that will keep out the moss, weeds and algae, prevent efflorescence and create a paved area that is mostly self-cleaning.

Our Top Pick
Stonecare4u

PROS

  • Easy to apply and great for DIY’ers
  • Extremely fast drying times
  • It’s free from solvents, making your patio area safe for kids and pets
  • Drastically reduces weed growth

CONS

  • A high price for a premium blend


#2. Best Wet Look Porcelain Sealer


#3. Best Polished Porcelain Tile Sealer – LTP Polished Porcelain

LTP’s Polished Porcelain Sealer (MPG) is one of the best sealers on the market for premium stones such as marble and slate. It is an affordable choice for sealing countertops, flooring, fireplaces and even walls.

One litre is normally enough to cover at least 10 square metres of tile with a polished finish. LTP advises, however, that this may vary depending on water absorption – you could get as much as 30 square metres from a standard 1-litre bottle.

If you need a bit less for a small patch in the garden or a bulk pack to cover your kitchen tiles, you’re in luck. LTP also provides this sealer in 500ml and 5-litre bottles, should you want to cover your entire floor or wall in a thin coat.

It’s likely to be an appealing choice if you want to start applying sealer without changing the look or colour of your stone. It’s a colour-freeimpregnating sealer. It works great with LTP aftercare products such as Waxwash, too.

Our 3rd Pick
LTP Polished Porcelain Sealer (MPG) 1 LITRE

PROS

  • Prevents dirt, oil, grease and water-based stains from penetrating glossy porcelain
  • Very easy to apply with brushes
  • Can be used inside and outside the building
  • Can also help to protect other natural stone
  • Applies thinly and cleanly

CONS

  • Make sure to wear a mask to protect against vapours.


#4. Water-Based (Solvent Free) Porcelain Patio Sealer – ECOPROTEC

LTP’s Polished Porcelain Sealer (MPG) is one of the best sealers on the market for premium stones such as marble and slate. It is an affordable choice for sealing countertops, flooring, fireplaces and even walls.

One litre is normally enough to cover at least 10 square metres of tile with a polished finish. LTP advises, however, that this may vary depending on water absorption – you could get as much as 30 square metres from a standard 1-litre bottle.

If you need a bit less for a small patch in the garden or a bulk pack to cover your kitchen tiles, you’re in luck. LTP also provides this sealer in 500ml and 5-litre bottles, should you want to cover your entire floor or wall in a thin coat.

A good choice if you want to avoid solvent-based sealers, this water-based tile sealer gives you an invisible layer. It’s low on noxious smells and doesn’t contain any VOCs. For double the benefit, you can apply it to different textures of porcelain before the grout. However, you’ll need to seal your tiles after the grout, too, to help protect against staining. For complete ease, lay it on with a foam roller – no more straining!

Solvent Free
ECOPROTEC

PROS

  • Great tile sealer for indoors and outdoors
  • No harmful chemicals – safe for pets, kids and you
  • Good for compound release
  • Goes down thinly – the bottle goes a long way

CONS

  • May not offer the same long-term protection as a solvent-based sealer.


#5. The Top Grout Sealer For Porcelain Tiles – LTP Porcelain Tile Protector

LTP’s Porcelain Tile Protector is a treatment for your tile floor pre-grout joints, with 1 litre and 5-litre bottles available. It’s a water-based treatment and offers up to 30 square metres of coverage per litre. Keep in mind, that’s for the least porous of surfaces.

The larger bottle might well cover your patio and your kitchen – and why not, given that you can use this tile sealer with interior and exterior surfaces.

The aftercare and cleaning involved with this tile sealer is a doddle, likely only needing a quick wash and a sweep once all is dry.

This is a versatile sealer, and you can apply it with a foam roller or paintbrush. However, you could do yourself a favour with larger areas as LTP also recommends using light pressure sprayers – the choice is yours!

Solvent Free
LTP Porcelain Tile Protector

PROS

  • Very eco-friendly option
  • No visible layer
  • Works with nearly all textured porcelain
  • Trusted by builders and paving experts
  • Blocks stains and makes grout haze easy to remove

CONS

  • Again – grout surfaces may benefit more from solvent.


Benefits Of Using Porcelain Slab Sealer

1) The Best Porcelain Sealants Will Enhance Natural Stone

The best porcelain surface sealers will help protect the look of natural stones as they lower the surface porosity. However, some sealants soak deeper into the substrate. These are called impregnators and can transform the look of a tile by adding tone or depth to the colour, even changing the contrast altogether. Floorseal confirms, for example, that their porcelain patio tile sealer actively deepens the colour.

2) Natural Look Sealers Allow for Unglazed Tiles

Many of us prefer the natural beauty of a porous surface to a glossy or glazed tile. Natural look sealers do more than add a surface to the substrate, instead of soaking deeper into the tile’s pores to protect and retain a natural look. The great thing about this means you do not have to compromise on the look of your tile for the sake of giving it added protection. Be careful; not all sealers offer an unglazed finish, so keep this in mind when shopping around.

3) Stain Protection & Stain Resistance

During manufacturing, porcelain and other polished surfaces can develop tiny pores that upon up. These almost microscopic gaps in the surface can allow stains and dirt to settle, spoil and damage the look of your stone. By impregnating your tile with sealer, you are effectively closing up these pores – reducing the likelihood of stains getting through and causing you more work in the long run.

4) Long-Lasting Protection

The best sealer on the market is going to create a barrier over your tile that will shut out spillages and stains for years to come. ECOPROTEC, for example, offers up to ten years of tile protection through its polished porcelain sealer. Dirt, water, oil and grease simply can’t penetrate the surface polymers once the sealer dries. Of course, if you have unpolished tiles or surfaces, protection time will vary. Always check the bottle in case you need a further coat, and keep in mind that protection time varies with different brands.

5) Easy Maintenance

If you’re sick and tired of having to scrub deeply into your tiles to get out dirt and grime, then you need to get yourself some tile sealer. Sealing your porcelain off means that there will be less for you to do in the long run, and the protective layer created will only ever need a quick wipe and/or sweep. It’s the difference between getting down deep with a scrubbing brush every week or a quick wash over. You’ll need a brilliant porcelain tile sealer for that kind of freedom!

Sealing Outdoor Porcelain Tiles – What To Do & What Not To Do

Do’s

1) Clean the entire area to remove mildew growth and any weeds. Sealing your tiles also means sealing in your greenery if you’re not careful. By getting the nasty undergrowth up and out of the way before you seal, you don’t stand to lock in anything that’ll undo your hard work accidentally. The best solvent-based sealers may even prevent weeds from coming back.

2) Try a test patch behind a shed or out of the way. Even the best selling sealers on the market will tell you that they will ‘definitely work’ – but it’s always a good idea to check before sealing the whole of your tile run. You never really know what your tile surface will look like under sealing until you actually apply it. Therefore, it makes sense to check you’re truly happy with the results before pressing onward.

3) Completely dry before sealing. A wet surface isn’t just going to add extra time to the tile and grout sealing process; it could lead to the whole project falling flat on its face. To avoid spoiling the seal and wasting time and money, you ideally need to leave your outdoor surface to dry for 24 hours before applying the sealer. In some cases, you’ll need even longer, but it pays to be certain.

Don’ts

1) Avoid Water-Based Sealer For Porcelain Tile Floors

Water-based sealants are cheap, whereas porcelain is anything but. We’ve included a water-based sealer in the list above, but we wouldn’t be in a rush to use water-based products when sealing these floor tiles. We would rather not seal at all or wait until we can afford a high-quality porcelain paving sealer designed to work with this stone and not use a one-size-fits-all solution.

2) Don’t Seal Porcelain If Rain is Expected

As mentioned, water isn’t your best friend when it comes to sealing. Just as you need to keep your surface dry before you apply a sealer, you’ll need to start the process on a dry day. Check the drying and sealing time on your tile sealer before application, too. If there’s rain expected somewhere into the window, always be sure to delay things by a few days to let it pass – and then to dry things out again. Generally, it’s best to get into tile sealing in summer.

3) Don’t Seal Over Any Droppings, Oil-Based Stains (or Any Stains for That Matter)

This might be fairly obvious, but if you seal over any animal mess or staining, it’s locked in. The same applies to weeds and mildew to some extent. We can’t stress enough how important it is to get your tiles and slabs absolutely clean and dry. The best tile sealer isn’t just going to lock in the natural look of your stone; it’s going to trap dirt, grout haze, and even bits of animal droppings.

4) Excess Sealer

Tile and grout sealer normally only needs a small, thin layer to start setting. If you’re new to sealing tile and grout, it can be very easy to go overboard – using too little is much safer than using too much. Roll your sealer brush thoroughly to avoid leaving any excess behind; otherwise, you’ll end up with uneven, patchy results. As always, follow the instructions on your tile and grout sealer and measure carefully.

5) Avoid Sealing a Previously Sealed Surface

Sealing any tile or surface twice – unless you know exactly the brand of sealer used – is never a good idea. Different sealers have different effects, and unfortunately, you can never guarantee that they will always work together on the same tile and grout. If you’re not sure which sealer was previously used, you may need to either clean your surface thoroughly or even completely refit your tiles in extreme circumstances.

The Top Porcelain Sealant Manufacturers

Floorseal

Floorseal is a well-trusted sealant manufacturer based up in Hepworth, near Holmfirth in West Yorkshire. Floorseal’s main appeal is that their grout sealer and tile protection lines are made with professionals in mind. Therefore, any builders and tilers undertaking regular sealing will likely recognise the brand.

The Floorseal brand is also synonymous with patio cleaning and preparation. Their website advises that their tile products work on a huge variety of natural stone and surface choices. Their focus is largely on producing fast-acting, easy-use cleaning and sealing solutions. That tends to be what most sealer manufacturers go for, but Floorseal actually follows through on their promises – take it from us as professionals.

We also really like that Floorseal doesn’t need to resort to solvent-based sealers to get fantastic results. Water-based solutions aren’t always the best for locking in porcelain tile and grout (or even ceramic tile), but this company clearly tests its products to a thorough standard.

ECOPROTEC

ECOPROTEC is a stone and tile specialist with more than three decades of experience in the sealing trade. One of their main focuses in developing tile and grout sealers is to produce solutions that are kind to the environment. This, again, means that much of their tile sealing range is water-based. As with Floorseal above, while water isn’t the best choice for porcelain, you at least know you’re investing in a reliable brand.

Beyond sustainability, ECOPROTEC products are designed to help lock in looks for both ceramic and porcelain and natural stone tiles. Their products aren’t just great for floor tiles, as you can find a range of products in their catalogue that extend to masonry and concrete applications.

ECOPROTEC informs us that their tile products endure years and years of use, with up to 10 years’ protection assured in many cases. The ECOPROTEC range also helps prevent the need for regular cleaning, meaning they’re reliable when getting rid of grout haze and locking in a ceramic or porcelain look that turns heads.

LTP

LTP is pretty much a one-stop-shop for all kinds of grout sealer, tile cleaning and aftercare. They’re a trusted brand amongst professionals in the trade, and rather than sticking to one particular niche, they provide products to cater to just about all your tile and grout wants. That covers tile sealing with solvent-based mixes and water bases, epoxy grout cleaning, waxes and more.

LTP also provides brushes and tools that you can use to coat and clean your tiles, grout and porcelain with – meaning that if you don’t already have these bits and pieces to hand, you really won’t have to look too far.

LTP’s three-level care system is fairly novel, in that ‘clean’ is level 1, ‘seal’ is level 2, and ‘care’ is level 3. They aim to cover you for each step of the tile care process. Even if you’re just looking for a top sealant for porcelain tile flooring, it makes sense to stock up on a few other essentials.

Stonecare4U

Stonecare4U, or SC4U, is a great brand that we’re very familiar with. They tend to lean more towards the budget end of the market; however, that doesn’t mean you go away with poor-quality products. What we really like about the SC4U range is that it’s appealing to both professionals as well as DIY enthusiasts.

SC4U has an ‘Excellent’ rating on Trustpilot (4.6 out of 5 stars) at the time of writing. Their formulas go through intensive research and testing, meaning that anyone buying their lines can expect great results (if they use their chosen products properly).

We highly recommend SC4U as a reliable brand and free from fluff and marketing traps for their product line. What you see on the bottle is what you get on the inside, which counts for sealing porcelain tile, natural stone, and ceramic tile. Other experts in outdoor tiles and indoor grout will agree with us here – SC4U is amongst the best of the best.

Azpects EasySeal

Azpects is a DIY brand that extends beyond just cleaning and sealing tiles. EasySeal is their tile care line, but they also have EasyGarden products to help clean patios and decking and EasyJoint for all your compound demands. If you’re a professional tiler or paver or have plenty of different DIY jobs coming up, Azpects tends to be a safe pair of hands.

Beyond grout and joint compounds, Azpects does also have its own EasyPorcelain line. EasyPrime, as you might expect, is a primer that’s useful across natural stone and porcelain, and their EasyGrout – of course – helps support porcelain paving grout. These specially designed products are likely to appeal to ceramic and porcelain users alike.

Azpects also supports customers with grout and tile needs by supplying useful online calculators via their website. This means if you are ever in doubt about how much product you actually need, the supplier will help you find the best fit (saving you cash along the way).

If you prefer more specialised products from a company that mainly focuses on tiles and sealing alone, it’s worth first checking out the brands and companies listed above.

Last Word

Any porcelain tile floor will demand a lot of care and attention if you want to keep it looking great. That goes for the grout, the finish, and just keeping a clean surface. Porcelain is, by and large, also going to demand a fair investment from you when it comes to cleaning and sealing products. If you’re completely new to this kind of tile and its grout, it pays to shop with trusted sealer manufacturers.

Top porcelain sealer products will help you protect your tiles against stains, organic matter, wear and tear. They’ll also cut down the cleaning and maintenance on your grout and surfaces, meaning you can give your tiles a quick wipe to lift off nuisance stains if they ever arise.

Ceramic and porcelain tile sealers should protect the initial look of your stone or porous tiles and protect them against the elements for up to ten years. We’d argue that most natural stone tiles and otherwise require sealing, and if you really want to make the most of them, shop for tile sealers and grout sealers that builders and pavers trust.

Ceramic and porcelain might seem like a nightmare to care for at first. However, it may just be that you’ve not found the best products yet. Hopefully this guide has helped to point you in the right direction!

(Of course, we’ve only covered porcelain, not ceramic tiles here. Many people put ceramic and porcelain tiles in the same category; however, a ceramic tile is much more porous. Look for a specialist tile sealer for ceramic and grout if in doubt.)

Our 1st Choice
Stonecare4u

We’ve chosen the Stonecare4u – Essential All Stone Sealer (Matt ‘Dry’ Finish) as our number one pick of all the porcelain sealers we reviewed. It’s the best tile sealer in terms of value, reliability, and you won’t need a second coat straight away.

It may be a little more expensive than your usual ceramic tile and grout sealer options, but when it comes to porcelain, you’re going to need a surface sealer and protective barrier that endures time, weather, common staining and more. This exceptional product dries quickly and won’t harm your animals or children – there’s absolutely no solvent in the mix. It’s the best porcelain paving sealer on the market for sheer value alone.
