Can You Install Brick Slips Directly Onto Blocks?

If you have stripped your existing walls back to the blockwork, then you might be wondering what your next step might be? Sure, you could plasterboard the walls and go down the traditional route of painting your walls but where is the fun in that? If you’re looking for a quirky look that is on trend then you might want to consider installing brick slips.

Unique and easy to install, they will transform the look and feel of your home. They also offer exceptional durability, regardless of where they are used. However, if you have bare blockwork, you might be tempted to install the brick slips on top of them but is this possible?


Things to Consider

There are some things that you need to consider before you install your brick slips onto block work. The main thing that you’ll need to do is to check the wall for any problems such as cracks, damp or loose sections. If you spot any of these problems, you will need to rectify them before you take the next step.

However, once you have checked the wall over and rectified the issues, you can begin to start the process of installing your brick slips.


What Next?

Brick slips are fitted to walls using an adhesive but for the adhesive to work, it’s important that it is able to set correctly but this is where you will need to consider the bare blockwork that they are being fitted to. Blocks are porous which means that they have a high level of suction or absorption. Therefore, when you apply the adhesive to the blockwork, some of the moisture will be taken from the adhesive… what is the issue you might be wondering?

The issue is that adhesive is mixed with water and it needs the right amount of water for the chemical reaction to take place. This will enable the adhesive to harden, bond and create a solid finish that keeps the brick slips on the wall. However, remove some of that water and everything changes!

Your adhesive will become weaker, it will take longer to harden and it could mean that your brick slips don’t bond. What this means is that you have to take care of some prep work before you install the brick slips.

To ensure that the walls are ready to accept the brick slips, you need to create the perfect surface. To ensure that no moisture is removed from the adhesive, a coat of diluted PVA should be applied to the blocks. This will seal them and prevent the blocks from taking water from the adhesive.

Once the wall has been PVA’d and it has dried you can then begin to install your brick slips. As with all jobs, it is always worth taking care of the prep work. The last thing you want is for your brick slips to fall away from the wall as this will mean that you have to take care of the job all over again.
