1 cement powder surface wet a: the reason is that the internal leakage, due to the internal water, so that the moisture seeps from the walls, processing method of the internal water, seepage removed, and waterproof measures, will limber (drainage) export processing good, again to prevent water seepage.
2 base adjustment: remove dirt, cement powder at the surface, to be wiped out, smooth or flat.
3. The cement surface sometimes crack, powder: the phenomenon should be pay attention to crack crack size, see the degree of pulverization of smooth, if the crack is a structure, you must first fill joints, if it is cracked, as long as adjust repair can be, in case of powder must strengthening powder site, to osmotic priming spray can be, if not eliminated powder have first with osmotic priming, then another batch of cement (cement shall be with osmotic priming), to the surface to be smooth and flat.
4. Cement face concave hole, missing angle, the flatness is not the same, the concave hole part: in addition to the cave is too large to be by the owners to repair, the rest of the small hole is by construction repair.
If the fixed point or protruding reinforced wall 5: General high-rise or cottage construction will scaffolding, and scaffolding fixed point are nail on the wall surface, so the best and most effective treatment method is transfer of fixed point, fixed point does not affect the repair of beautiful, and protruding reinforced, if in the future additional words, there is no need to wear off, but must make antirust processing, and paint.
6 surface treatment: cement powder status: most of the surface will have powder, dirt must be clean.
