Top Picks for Brush In Indian Sandstone Grout

Indian Sandstone is a popular choice for paving or a new patio, but using a traditional sand and mortar mix to fill the gaps can result in staining the natural stone’s surface. To avoid this, we recommend using grout for Indian Sandstone that won’t damage the stones. Let’s see which ticks all the boxes.

#1. Easy Joint

Recommended by tradesmen and DIY enthusiasts alike, this is the UK’s bestselling Indian Sandstone patio grout and for a good reason. 

Not only is it one of if not the most straightforward Indian stone jointing compounds to apply, but you also don’t need to worry about the weather. Suitable for all types of paving, including Indian Sandstone, it works for joints 3mm and above, perfect for this naturally cut stone where joints are often more expansive. 

Creating a solid joint that won’t discolour or stain lasts for years. Easy Joint patio grout is also an excellent value, costing much less than some paving joint methods.

  • It comes in an array of colours (Buff, Basalt, Mushroom, Grey and Jet Black) 
  • Unused grout can be kept for up to 12 months 
  • Water-resistant 

Cons

#2. Sika FastFix All Weather

Extremely easy to use; soak the stone surfaces before using a soft brush to sweep the grout into the paving joints. Sika FastFix All Weather will start to cure in about 6-12 hours in warm, dry conditions, but it can take up to 5 days for the grout to set completely. 

Once set. However, it provides an aesthetically pleasing and durable joint filler providing a natural weed barrier that won’t shrink or crack. 

Coverage, of course, depends on the thickness of your Indian Sandstone slabs and the depth and widths of the joints, but a 15kg tub of Sika FastFix should cover around 19 square metres.

  • Ideal for natural stone with joints of 5mm plus 
  • It can be applied rain or shine. 
  • It can be purchased in a bundle with sealant.

How To Choose Sandstone Paving Grout

You might think choosing the best Indian Sandstone paving grout is a simple task, but there are a few considerations to be aware of. 

Colours

Patio grout comes in several colours, meaning you can create a unique look by using matching colours to provide a seamless modern finish. Alternatively, you may prefer a contrasting tone for your sandstone grout colour, which, when the gaps are filled, will make your patio pop! 

Long Lasting

Natural stone is one of the longest-lasting landscaping materials, so you need durable grout for Indian Sandstone slabs; otherwise, it deteriorates quickly. All the patio grouts in this guide provide long-lasting results, although you must be careful if you regularly jet-wash the area. 

Quick Set Grouting

Different types of grout need different setting times. Most can take light foot traffic after a few hours; however, depending on weather conditions, it can be 2-3 days before they are fully set, depending on weather conditions. 

Affordable

You’ve already spent a good amount if you have an Indian Sandstone patio, so the last thing you need is to spend lots more cash on a suitable grout. Epoxy resin Sandstone grouts will cost more, but we’ve found that the products reviewed above are excellent and cheaper alternatives. 

Easy to sweep in, pointing

Grouting sandstone pavers shouldn’t be hard. The best options require minimum effort to apply and, at most, need neatening with a trowel to produce a strong and attractive joint. 

Types Of Outdoor Sandstone Pointing Mix

Epoxy

Epoxy patio grouts make an excellent jointing compound for Indian Sandstone as they form non-porous, durable joints impervious to staining and weather. 

That being said, they are the most expensive type of Indian Sandstone grout. It’s also more challenging to work with and, if not applied correctly, can cause issues with Indian sandstone, so it’s essential to read the manufacturer’s instructions carefully. 

Brush in

Much like sand and cement brush in, patio grouts are easy to apply and can be either applied as a slurry or soaked once the grout is in the gaps. These are probably the most common types of grout used for Indian Sandstone as they are relatively cost-effective, although they can be a little messy. 

Pre-mixed

Ready mix grouts work the same way, and some are even as strong and durable as epoxy grouts for Sandstone. These grouts are incredibly versatile; they can be applied in any weather conditions and used either indoors or outside. 

FAQ’s

What do you put in between Indian sandstone?

You can use jointing compounds, kiln-dried sand, cement, or patio grout between Indian Sandstone slabs. We strongly advise using a cement-free option, however, to prevent stains. 

What is the gap between Indian sandstone?

The gap for most other paving surfaces is 3mm and above, but often due to being a natural material, the gaps in Indian Sandstone are quite a bit larger. 

Is it best to seal Indian sandstone before grouting?

We’d recommend sealing after the jointing has settled. Maybe leave a week or two, or new installations leave for at least 8-12 weeks. Here are the best sealing products use in Indian stone paving.
