How to deal with the operation and acceptance of ash removal, and what are the quality and standards of ash removal project?

In home decoration, you will encounter the problem of fan dust. If it is not handled properly, it will lead to slow renovation progress and unqualified products. The bottom ash of the original wall should be removed without residue. When the overall wall surface reaches the flatness, remove the dust generated by grinding the wall surface, and then brush the primer and topcoat.

The most important thing is to check the overall appearance and flatness of the wall after dust removal. After the wall paint is dried, it will pass the visual inspection and feel acceptance under natural light. The flatness acceptance mainly depends on checking the corner deviation and the vertical flatness of the wall.

The quality standard of fan ash engineering mainly depends on whether there is obvious color difference, pan-alkali, color reversion, brush lines and other phenomena on the wall surface, and check whether there is powder falling and brush leakage on the wall surface. The verticality deviation value of wall paint is generally 5mm, and the levelness deviation value is generally 4 mm. By checking these two items, mistakes caused by fan ash can be basically ruled out.

Home improvement is not a simple matter, and every step should be taken seriously. Only in this way can we avoid unnecessary problems when staying in the future.
