How To Clean Cement Screed Walls

[apollo75 0]

Hi everyone,

Need some advice here. I cement screed my walls in my bathroom. I am having problem with cleaning the walls as it is very porous, thus it traps alot of (dunno what you call that ) yellowish stain. I intend to laquer it, but before that i need to really clean it.

Anyone knows how to do it? I tried using easy-bang (something like that) but it's not easy to clean.

Thanks

Try using a tooth brush soaed in diluted acid to clean it off.
