Can I use sealant on brick wall

Our house currently has very pale brick walls, which I dislike. However when the brick is wet I find the colour very nice because it is darker. I was thinking of using a sealant to get this effect. Does anybody know more about this? Someone recommended concrete floor sealant, someone else told me this would be bad because brick had to breathe???

Can I use sealant on brick wall

I wouldn't seal the brick myself. If you do, be carefull of the type of sealer.

A brick wall must be able to breathe. Many clay brick are durable under normal conditions, but will spall (face come off) is moisture is trapes in the brick.

Sealers are coatings. Coatings deteriorate and must be re-applied. If they are applied too thickly or build up too much, the brick could spall if the sealer does nor peel off. Since sealers are clear it is very difficult to determine if the correct amount is applied.

Even an excellent breathing sealer can become a non-brething sealer if recoated.

I hope this helps.

Thank you very much for your reply you are very helpfull. Do you know of any product I could use that is not a scellant which would simply darken the brick or make it seem wet.

I am not aware of any product made for those purposes. The types of products I mentioned could make the brick appear darker. There are also sealers for concrete pavers that do the same thing. With all of these you have to pay attention to the recommended applications and uses and not get side-tracked by phrases like "can be used for..."

Once you start coating, you could get locked into recoating forever.

Go to Prosoco.com, they have many sealers that release any locked in moisture and prevent moisture from entering brickwork. Read the material data sheets for more info. or contact them for more info.

Saver Systems of Richmond IN sell a clear solution called "chimney saver" which is a waterproofing coating that is 100% breathable. It can be used on any kind of brick and masonry surface but is especially used for chimneys because the possibility of trapped water and subsequent spalling is of particular concern in this application. I believe it is only sold to the trade so you might have to hire a professional to apply it.
Good luck

This will sound like I'm on drugs but could you use a wood stain like Minwax to change the color of the brick? Or would wood stain also act as a sealer and cause the problems previously discussed?

I would be interested in hearing what the pros have to say.
