Grouting a patio isn’t difficult, but it needs to be done correctly; otherwise, your pointing won’t last and those dreaded weeds will start to poke through. 

This article will give you all the information about patio pointing drying times so that you can achieve the best results for your project. 

How Long Does Pointing Drying Take?

Several factors can affect how long it takes for patio pointing to dry; it can take between 24 – 48 hours, depending on what you use and up to 28 days in cold, damp climates.

Sand & cement

There are few options when it comes to filling the joints in your patio, the most common being a sand and cement mortar mix. As the toughest method, a sand and cement mortar joint is often chosen for pointing on patios.

The process is typically done when the patio slabs have just been laid and must be done when the weather is dry, fine and frost-free so it can cure and harden. The mixture will start to set in a couple of hours, but it takes between 24 – 48 hours for it to become dry enough to walk on. 

Jointing compound 

Another method to point a patio is to use a is to use a ready mix jointing compound. This product is designed to make filling the gaps between your patio slabs as easy as possible. 

They contain setting agents and hardeners to create a flexible hard wearing joint and are generally dry in around 12-24 hours. However, they are more expensive and must be used quickly, especially in warm weather, to prevent them from hardening too fast.  

Many jointing products, like EasyJoint by Azpects and Geofix grout, can be applied in all weather conditions. However, it’s essential to follow the manufacturers’ instructions and it is also worth checking the suitability of the surface to be pointed. They also come in various colours to produce an aesthetically pleasing finish. 

Will Brush in Patio Pointing Dry Quicker?

This method of patio pointing can simply be brushed in with a stiff broom and the edges smoothed, but does brush in patio pointing dry quicker? Yes, brush-in pointing dries far quicker than many others on the market. Permeable and fast drying, you can usually walk on the slabs in about 6 hours, although we recommend leaving it for 24 just to be safe. 

Does Rain Affect Pointing?

Should you point in the rain? Rain doesn’t affect pointing as much as you would expect and a light shower won’t hurt. However, a heavy downpour may cause the grout to wash out of the joints and in some cases, especially when using grout on a natural stone, the flags can be stained when wet. You can also find out how long should patio pointing last with this article and what you can to do to maintain it.

Last Word

We hope this article gives you some insights on how long you’ll need to wait for your patio pointing to dry. A standard sand and cement mortar mix will typically take between 1-2 days to dry; however, this could be much longer depending on the weather conditions, sometimes taking up to four weeks to harden completely. 

Ready mix jointing compounds make the job much easier and the added chemicals mean this kind of grout sets quicker too. Although they cost considerably more, they have many benefits, such as more flexibility and added weed prevention and are usually good enough to walk on in just a few hours. 

Whichever you choose, it’s best to point your patio on a dry fine day with no chance of frost, that way; you’ll have peace of mind that the joints will dry and give the finished look you’re after
