How to use brush-in grouts
When it comes to grouting outdoor tiles, the process is similar to indoor grout, albeit with a few differences.
The main difference is making sure you are using a grout that is suitable for outdoor use. Although it might seem obvious you would be surprised how many people don’t check beforehand and end up using the wrong grout.
So, make sure to read on to discover which grout you should be using together with the easiest way to grout your tiles in your garden.
Why do you need to grout outdoor tiles?
If you think your tiles indoors get a tough time, that’s nothing compared with your outdoor tiles considering what they have to put up with – namely the Great British Weather!
Grouting your outdoor tiles is one of the best ways to protect them against the elements. Grouting the joints between your patio slabs stops the build-up of dirt and other debris that could potentially damage your tiles.
Which grout should you use with outdoor tiles?
There are two main types of grouts most commonly used with outdoor tiles – cement-based grouts or brush-in grouts.
The former is the best known and historically been the most popular but in recent years it has been superseded by the latter – thanks to its ease of use, and the fact that it can be applied in most weathers.
When should you grout outdoor tiles?
Both types of outdoor grout ideally need to be applied when the temperature is above 10oC and less than 40oC which means anytime from March through to October.
The best way to apply brush-in grout – a step by step guide
Sweep your patio to remove any debris from the surface of your outdoor tiles. Don’t forget to do the same to your grout joints as any dirt left behind could potentially contaminate your grout.
Wet your patio with water but don’t soak your slabs. They need to be damp for your brush-in grout to be fully effective and to prevent the jointing staining the tiles.
Always read the manufacturer’s instructions prior to application. Once you are happy you’ve fully understood them start pouring the brush-in along your grout joints.
We would recommend using a brush to help sweep any grout that might have escaped onto the tiles back into the joints as well as a trowel to compact the grout. Top up the grout joint after compacting and repeat until you’ve got your desired level.
Once you’ve worked in all the brush-in grout, sweep up any residue from your tiles and dispose of it carefully.
After about 30 minutes give your tiles a good clean with water to remove any grout residue from the surface of your patio tiles.
How long does outdoor grout take to set?
Always follow the manufacturer’s instructions when it comes to setting times, but the rule of thumb is anything between 24 to 48 hours – depending on the temperature as well as if it rains (in which case it may take longer).
The end results will be well worth it though. Thanks to the use of grout, you’ll be left with a weed free patio to enjoy with family and friends for many years to come, and one that will also require little in the way of maintenance, other than a spring clean.
