Embodiment

A, repairing

1:3 cement mortar or polymer cement mortar is adopted to repair for the defect such as losing fangle place, hole of matrix before applying.Be specific practice below: hollowing---hollowing position is all rooted out, cleans out, again do basic unit and repair;

Gap---fine cracks adopts putty to carry out repairing (require during repairing thin batch and unsuitable thick brush), ties after dry with sand paper; For large crack, location of cracks can be cut a hole into " V " font gap, pointing 1:2.5 cement mortar after cleaning is clean, smears putty after dry and uses sand papering smooth again;

Hole---the hole of below 3mm below substrate surface, adopts polymer cement putty to carry out levelling, and the hole being greater than 3mm adopts cement mortar to carry out repairing and after dry, smear putty use sand papering smooth again.

In addition for new cement mortar surface, when brushing as being badly in need of, the zinc sulfate of 15%-20% concentration or burnett's solution can be adopted to be painted on cement mortar substrate surface for several times, the powder that rear removing surface to be dried is separated out and floating sand can be brushed.

B, cleaning

Dust, powder can use broom, hairbrush to clean, and grease uses neutral detergent cleaning, and mortar shovels, scrapes

The removings such as cutter, mould clear water rinsing is dried.

C, putty bottoming are levelling

Main purpose is to repair irregular phenomenon, prevents pore and the crack on surface.The requirement of putty, except easily criticizing easily polishing, also should possess good intensity and persistence, carrying out filling up, local Puttying construction time requirement, should thin batch and unsuitable thick brush.Construction technology during Puttying is as follows:

1. the gradient of instrument during blade coating is grasped, firmly evenly, to ensure that putty is full;

2. excessive for avoiding putty to shrink, occur cracking and come off, one time blade coating is not blocked up, and according to the feature of different putty, thickness is advisable with 0.5mm.Not do not come and go blade coating too much, in order to avoid occur that volume skin comes off or the sizing material in putty extruded to seal surface not easily dry;

3. fill out with putty knife and will fill up, tamp, when there are hole and a crack in basic unit, forefinger compresses blade, firmly putty is compressed into defect, is received by the putty of surrounding to scrape clean, makes the vestige minimizing as far as possible of putty.

D, polishing

Polish with emery cloth and accomplish surfacing, degree of roughness unanimously, texture texture is even.This procedure calls rechecking, polishing are until when surperficial perception is consistent.

1. can not wet-milling, polishing must be carried out after basic unit or putty drying, in order to avoid adhere to sand paper impact operation;

2. the thickness of sand paper will be determined according to by the hardness on mill surface, and sand paper is thick can produce sand trace, affects the final decorative effect of coating;

3. sand paper (cloth) should wrap on polishing cushion block by manual grinding, back and forth enforces, and only can not press against sand papering with one or two finger, with the planeness of rabbit impact polishing;
