How to deal with concrete floor paint of Yichang new factory building

Workshop foundation treatment scheme is as follows:

(1) For cement or terrazzo floors with oil stains (cooking oil, engine oil, etc.). ), first sprinkle sodium hydroxide (commonly known as caustic soda) on the ground that has been washed with water, scrub it repeatedly with a bamboo broom, and then rinse it with water, which can be repeated for 2 ~ 3 times until there is no oil stain on the surface. Construction personnel should wear boots and rubber gloves to prevent caustic soda from corroding the skin.

For the ground with old paint, if the paint is easy to peel off, it must be thoroughly removed or polished before construction. If most paint surfaces have good adhesion and do not react with floor paint, first remove the paint skin that is easy to fall off, and then roughen the surface of the old paint with a grinder or hand-held sandpaper to increase the interlayer adhesion of the new paint.

(3) For the ground that has been waxed, it is necessary to clean it with wax removal water or ask cleaning company to remove wax.

(4) All rust-proof paints, latex paints, bubble gum and asphalt paints that fall to the ground must be shoveled off.

5] The uneven ground with cement caking and cement scum shall be polished with diamond water mill first, then cleaned and vacuumed.
