Before the construction of emulsioni paint, the paint project has an impact on other civil engineering and water, electricity and other installation works should have been completed. The water content of plastering surface shall not be greater than 10%(including the water content after all kinds of holes are laid and flattened). The finished floor is covered and protected in advance.
1. Construction sequence:
Cleaning → fill gaps → first time full scraping putty → second time full scraping putty → third time full scraping putty → polishing → adhesive tape → first sealing primer → filling putty → polishing → first latex paint → polishing → second latex paint → polishing → third latex paint.
2. Construction method
(1) Basic treatment
(1) cleaning: the first plastering surface ash and bumps and other debris with tools such as cutting, such as the surface of the oil, such as kerosene wipe clean, and finally with a brown brush to clean the surface of the dust. The screw of plasterboard and three-ply board undertake antirust treatment, three-ply board brushs varnish again, stick board seam with dacron cloth next, prevent crack.
(2) fill the gap: after surface cleaning, with 801 glue, cement, old powder mixed with carboxymethyl cellulose to do putty will be wall pock, honeycomb, holes, incomplete place to fill, putty dry, first with shovel knife will be redundant putty shovel level.
(2) the first is full blow be bored with child When local blow be bored with child have larger gap fill level after polishing, scraping with a latex with rubber putty again, require wipe smooth, uniform, smooth, there shall not be wild putty, putty all tiny sand holes and former times after the shrinkage crack and the imperfect insufficient place, must be full, solid flat to the whole neat, the line Angle and edge. At the same time, it should be scraped along the object surface vertically, without leakage, the joint should be flat, and pay attention not to contaminate the door and window frames and other objects, otherwise, it should be cleaned up.
(3) the second time full blow putty this putty and putty scraping method is the same, the wall will be further scraped and polished smooth and smooth.
(four) the third time full blow putty, the third time full blow putty method is the same as before, make the wall level off, smooth, Yang Yin Angle vertical. Polishing: After the putty is dry, cover the flat small board with sandpaper, polish the putty slag and the rough parts, pay attention to even force, protect the edges and corners, and clean it with a brown broom after grinding.
(five) adhesive tape paper wood veneer part with adhesive tape.
(six) brush the primer brush the primer, and then fill the putty and polish.
(7) the first latex paint
(1) the first time latex paint must be cleaned before brushing the wall, wipe clean floating ash. Emulsioni paint should stir fully before use even, if consistency is bigger, not easy when besmear is brush, can add clear water dilution appropriately, but add water quantity every time must measure accurately, must not thin thick differ. Brushing when the row of pens, brushing order is generally from top to bottom, from left to right, first far after near, first horizontal after vertical, first edge, edges and corners, small face after the big face, Yin Angle shall not residual paint, Yang Angle shall not be wrapped. Such as a wall painting can not be from the top to the bottom, should be multi-level up and down at the same time, cooperate with each other, to avoid the phenomenon of senior, brush overlap. Stained on other surface of all the paint should be wiped with water, and pay attention to the protection of the surface has been coated, brushing method generally use oil brush paint, then hand with the brush to spread the good paint force horizontal and vertical cross will paint brush evenly, and then brush trace smooth. Each dip coating once, are continuous action, at one go, and pay attention to each brush should be "less dip material, dip many times ", as far as possible to reduce the number of horizontal coating, oblique coating, the best two back and forth can brush the paint open brush evenly. Individual surface each time with the same batch of paint, and should be completed once.
(2) fill putty: the first time after the latex paint is dry, a general inspection, such as defects should be local fill latex putty again, with horn scraping, so as not to damage the paint film.
(3) polishing: after the putty is dry, polish the coating surface smoothly with fine sand paper. Pay attention to the light and uniform force, and do not wear through the paint film. After grinding, clean the surface or wipe it with a clean damp cloth.
(eight) the second latex paint second latex paint brushing and polishing method is the same as the first time, there should be no color uneven or bottom phenomenon.
(9) the third latex paint
(1) the brushing sequence and method and the first latex paint is the same. Large area of the brush should be more than people with flow operation, link up with each other. Generally start from the inconspicuous head, and gradually brush to the other head step by step, until the inconspicuous brush, there shall be no senior and brush lines. If the chart is attached to the wall, remove it in time.
(2) All the positive corners are straighter and sanding with cement 107 mastic grease, and then sanding out 2-3mm small corner with fine sandpaper after painting.
(3) The skirting line according to the prescribed height of the line, and then paste the wall paint with newspaper, the newspaper is removed.
(4) The ground should be covered with cloth and paper.
3. Notes:
(1) Each time before brushing should be cleaned up the surrounding environment, to prevent dust pollution paint, paint is not dry before, shall not clean the ground, dry, shall not be close to the wall splashing water, so as not to contaminate the coating surface. After every besmear is brushed, should close door window, prevent to touch touch, also must not rely on a wall to put the tool such as shovel.
(2) In the construction of a sudden drop in temperature, exposure, etc., should be timely to take necessary measures to protect.
(3) Wear a mask and operate in the downwind direction when sandpaper is applied. 【 the 】
