    Any ideas on how to add a rough texture back to sanded bricks?


    Someone (definitely not me) went a little overboard sanding and removing paint from some bricks, and now some of those bricks are buttery smooth. Trouble is, they're adjacent to some natural/rough bricks. Any ideas on how I might renew their original rough texture?

    Could you carefully sandblast them?

    I should have done that from the start, but at this point Iíd rather not. Iím thinking a very abrasive wire brush might get me close enough.

    Wire wheel? Just a hammer and pick. Do you have pictures of what you’re trying to match?

    Ice axe.

    It really depends on what sort of "rough" you're looking for.

    acid etching, but don't wash it off, let it melt the brick

    always acid into water, never the other way

    Do they still have paint on them (or repainted), or are they bare brick now?

    are you sure they weren't smooth to begin with, I've seen some brick mfg'ers with very smooth textures, especially old bricks, there were brickyards all over that are no longer in existence.

    I'd be EXTREMELY careful doing that. Sandblasting bricks is primarily used for cleaning purposes. Jack that pressure up too much and you could turn them to dust!

    Thanks! I don't have a ton to do...realistically it's like 3-4 bricks that need help. I think wire wheel and chisel might be what I'll try next.

    They were rough to begin with. Hard to explain, but some were painted, some were not. I stripped some with chemicals, some with wire wheel, and some with too aggressive wire wheelin'.

    When bricks are fired, the process creates a glazed, super hard shell. The inside remains relatively soft. Wear away the crust through weathering, scrubbing, sanding, acid etch, physical blows or whatever and you expose the soft interior that will dissolve/crumble fairly quickly when exposed to the elements. Be very careful when "cleaning" or you'll end up replacing them sooner rather than later (and matching existing brick and mortar when they do need replacement is a non-trivial task.)

    Good tip, thanks! The exposed area on the ones that are smooth definitely feels like it could crumble.

    This is solid info. Never sandblast brick, or even pressure wash up close. The masons we work with always use an acid cleaner, a scrub brush, and lightly power wash it away. They also seal it a couple days after the wash.

    I don't know what your masons are sealing brick with but it has been demonstrated that if too water tight, the moisture that inevitably gets behind the brick veneer though condensation, cracks and/or water vapor migrating from the inside will freeze in this climate and significantly accelerate brick and mortar disintegration.

    This was a HUGE problem in the 60's and 70's with historic restoration work when people thought they were protecting fragile brick structures by spraying the exterior with a silicone solution. All they did was trap the naturally occurring moisture within the wall. Brick is porous. It needs to breathe.

    I donít know the product they used to seal the brick, it was in a 5 gallon bucket tho. Majority of our work is new commercial construction where the brick is just a veneer with a decent air gap on the backside. Maybe the condensation is thought to be eliminated with air from the inside?

    I'm not sure brick veneer is made the same as real brick. It breaks up differently, but that could be due to the size difference. I'm curious if they make it differently.

    on commercial projects, the veneer is a whole brick, not those fake slices

    If it is real (clay) brick, it has to be fired. The glue-on stuff can be made of composite material.
