Do I need to seal Brick slips after fitting?

Brick slips are becoming more and more popular in both the residential and commercial sectors. Ideal for use externally and internally, they provide a cost effective and stunning rustic brick wall look They're also easy to maintain but we are often asked, do you need to seal brick slips?

Sealing Brick Slips

Firstly, the vast majority of people do not use a sealant. The rustic and textured style is why you went for brick slips in the first place and they are highly durable, so sealing them is not a must.

However, if they are to be used in a environment where frequent cleaning will be required (behind a hob etc), or if you just have a clean freak in your house, it might be best to apply an appropriate sealant to protect the brick slip surface and to make them easier to clean.

Likewise an untreated slip brick can absorb liquid fairly easily due to their porous nature. so if you are planning to use them externally or behind a sink for example, it's also best to seal the brick slips

Clean the slips before you start

It's always best to clean the brick slips before you start. We've created a separate article for cleaning brick slips, which is worth reading before you start, but like most things in life, it's important you take your time and prepare well before starting!

If your brick slips have only recently been fitted, then do not follow our brick slip cleaning guide as it can take between 6 and 8 weeks for the mortar to fully cure.

Please be aware. If you seal the bricks without cleaning, any stains or marks will be 'sealed' onto the slips, so it's important that your remove them before, even if it means waiting a few weeks to clean the brick slips properly before sealing.
