b, repairing the defects of the unfilled corner, hole and the like of the base layer (the plastering surface) by using cement mortar or polymer cement mortar or high-strength putty in a mass ratio of 1:3 before repairing, cleaning and coating the base layer (the plastering surface), when a large area is hollowed, completely shoveling off the hollow part, cleaning, re-making the base layer, if the area is locally hollowed, repairing by using epoxy resin injected with low viscosity, repairing fine cracks by using putty, and leveling by using sand paper after drying; for large cracks, the crack parts can be chiseled into a V shape, a waterproof layer is made after cleaning, cement mortar with the mass ratio of 1:2.5 is filled, the cement mortar is ground and leveled by cement mortar paper after drying, holes with the diameter less than 3mm on the surface of a base layer are leveled by polymer cement putty, holes with the diameter more than 3mm adopt a water leakage source, GBS bi-component synthetic polymer waterproof paint is brushed twice to ensure that the leakage is prevented, if dust and powder exist in wall plastering, a broom, a brush and high-pressure water are used for washing; dirt such as grease and the like is cleaned by a neutral detergent; when residual mortar is present, the mortar is removed by using a tool such as a shovel or a scraper; cleaning the mould on the wall surface by using a steel wire brush, washing by using a high-pressure water gun, and drying;

and c, local putty plastering is pasted and repaired, the flatness and smoothness of a plastering layer of the wall surface meet the coating requirement, the plastering for filling the putty and the local putty can be omitted, and the plastered putty is easy to batch and polish, has better strength and durability, and further has good cohesiveness, durability and water resistance. When the putty is scraped, the inclination angle of a tool is controlled to be 45 degrees and the force is uniformly applied to ensure that the putty is full, and in order to avoid excessive shrinkage of the putty and cracking and falling of the putty, the putty is not scraped repeatedly by excessively thickening and excessively repeating once coating so as to avoid the phenomenon that a coil skin falls off, and gaps are filled and filled;

c treating the internal and external corners

And (3) constructing the internal and external corners, embedding the external corner strips into the external corner positions after the external corners are fully screeded by leveling putty, screeding the leveling putty, leveling the external corners on the wall surface, and contrasting by infrared rays at any time to ensure that the external corners are vertical. Constructing internal corners, namely, filling and leveling the non-straight parts of the internal corners after stirring the internal corner lines with leveling putty powder and water, leveling the non-straight parts until the internal corners are vertical by using a special tool, and requiring an instrument to measure the lines to be vertical;

the construction quality of the internal and external corners is an important prerequisite for ensuring the overall quality of the emulsion paint, and the key point is whether the treatment of the internal and external corners can reach the standard or not. The requirement of the yin-yang corner gold coin is as follows: the internal corner is smooth, and the external corner is square, straight and straight;

the following tools are prepared for the inner wall surface putty engineering construction: the aluminum alloy with different lengths is specially supported by a plurality of pieces, 1 ink fountain, 1 internal corner twist, 1 plumb bob and other matched tools;

before whole putty is criticized and is scraped, make yin yang angle earlier, should do before the reentrant corner construction and play line work, the reentrant corner plays the line scope and includes: the reentrant corner of wall and the reentrant corner of wall and top surface, the thickness and the welt of the control putty of should trying to get to the greatest extent when playing the line play the line, and the reentrant corner is played the line and should be gone on simultaneously with the reentrant corner construction, if: when the wall A is constructed, a line is bounced on the wall B, putty is scraped on the wall A along the line B, and the putty is pulled along the line B by using an aluminum alloy internal corner special ruler. After the putty on the surface A is well scraped, the inside corner line of the surface B is flicked, and the wall on the surface B is constructed by the same method. After the putty is dried, the internal corners are finished to be qualified by rubbing the internal corners by using the internal corners, the construction method of the internal corners of the wall surface and the top surface is the same, namely, the putty is prepared by using white glue and model gypsum powder, the putty is batched on two sides of the original external corner, then the corner strips are pasted on the putty, and after a special aluminum alloy ruler is used for straightening, the redundant putty is shoveled (the external corner of the wall surface is locally protruded and is firstly subjected to foot rubbing treatment, hammer lines are hung along two plastering surfaces when the external corner is pasted, and the perpendicularity and the highest part of the external corner strip protruded out of the original wall are not more than 2 mm).

The treatment for nail holes and moisture was as follows: 1) dipping rust-proof iron red paint into the part with the nail holes by using a small writing brush, adding gypsum powder into the mixture after the mixture is dried, uniformly mixing the gypsum powder with the iron red rust-proof paint, and scraping and filling the rust-proof part by using a scraper knife; 2) The wet part is coated with waterproof paint for one time, and the next procedure is carried out after the waterproof paint is completely dried;

4 plastering putty

4.2 the interior wall putty of the present invention is mainly applied in batches on two major categories of facings. One is a gypsum board surface layer (containing a wood surface), and the other is a plastering surface layer; compared with a plastering surface layer, the wooden surface layer has higher flatness, and does not need to be leveled by leveling putty; leveling putty is needed to be used for leveling the plastering surface layer, and then smooth surface putty is fully prepared (due to the fact that the building plastering surface layer has large flatness error, the phenomenon of unevenness is serious);

4.3 after leveling putty and scraping by using a cast iron plate, vertically and horizontally pulling and leveling for multiple times by using a 1m ruler; and after the smooth putty is scraped, the aluminum alloy ruler is used for carrying out longitudinal and transverse detection, repair and strickling at any time. Wall putty is criticized and is scraped to ground, and the skirting line installation position must adopt the length 2m above aluminum alloy ruler to detect, draw criticize, and the straightness error should be less than 2mm to ensure that the skirting line installation is level and straight-through, should make the mark or reserve spool groove part when meeting the spool groove, do not criticize putty. The principle of 'thin and thick is suitable for installation', the maximum thickness of the leveling putty should not exceed 20mm, and the smooth surface putty should not exceed 3 mm. The interval time of each putty batch scraping is not too short, and the batch scraping is carried out for 1 time after the previous putty is basically dried and primarily corrected, so that the phenomenon that a putty layer is cracked and even falls off is avoided;

4.4 when the second time of putty coating, the second time of putty coating is carried out, the putty coating is carried out after the first time of putty coating is dried completely, (whether the sound is produced or not can be checked by hand feeling, whether the putty is whitened or not can be checked by naked eyes to judge whether the putty is dried completely or not), and when the second time of putty coating is carried out, the putty is polished;

4.5 in the putty coating process, lighting with a tungsten iodine lamp for checking, and checking with light at night to ensure that the wall surface and the top surface are smooth, wherein the final polishing for 1 time is consistent with the light source irradiation direction, no shadow is generated during light irradiation, and the wall surface and the top surface which are constructed to be qualified are subjected to the next 1 procedure of brushing latex primer;

the invention should pay attention to the following items when the inner wall putty is constructed:

1) newly build a wall and wait to carry out batch puttying work again after the plastering layer is dry, otherwise can lead to the difficult volatilization of wall moisture, the putty dries up more slowly.

2) When products made of wood head boards, density boards, multi-layer boards and the like need putty scraping, all the products are scraped by oil putty and polished for forming, and the products cannot be directly applied to water-based putty or a drawing method to prevent wood materials from expanding, decoloring and deforming due to moisture;

3) when the kitchen, the toilet and the exposed balcony are wall surface emulsion paints, waterproof putty construction is required, and other requirements and processes are the same;

5 grinding

5.1 the base layer or the putty is ground after being dried so as to avoid the influence of the adhesion of abrasive paper on the operation, the thickness of the abrasive paper is determined according to the hardness of the ground surface, the sand marks are reduced as much as possible, and otherwise, the final decorative effect of the pattern layer is influenced. The manual grinding is to wrap the sand paper (cloth) on a grinding machine and lightly push the sand paper (cloth) on the base layer, so that the sand paper (cloth) can not be pressed forcefully during grinding to prevent the motor from being damaged due to overload. When polishing, firstly, the rough gauze is used for primary polishing, and then, the fine gauze is used for polishing. The surface flatness is required, and the roughness and texture after polishing are basically consistent. And leveling the plastering of the convex part on the surface by using a scraper knife, filling the plastering by using putty, and polishing by using abrasive paper after drying. After polishing, removing surface dust in time so as to facilitate normal construction of the next process; fine grinding is carried out by using 240# dry sand for one time along a straight line, and then 320# dry sand is used for transverse and straight grinding until the surface is flat and smooth, so that sand marks cannot be produced; for the internal corner, the 240# sand must be used for smoothing and polishing by matching with an internal corner ruler tool.

6 priming

6.1, cleaning floating ash on the base surface layer by using a feather duster until no floating ash is left on the hands;

6.2 when spraying the priming paint, uniformly thin-coating or spraying once to ensure that the priming paint completely permeates into the base layer, thereby increasing the firmness;

the amount of the 6.3 spray-on primer is the minimum amount to cover a base surface, and the area coated is from about 12 to about 15 square meters per liter, preferably about 13 square meters.

7 construction of inner wall latex primer and finish

7.1 latex paint types and Properties

The latex paint is divided into an inner wall latex paint and an outer wall latex paint according to product types, wherein the inner wall latex paint belongs to non-waterproof paint and is suitable for indoor finishing with small air humidity; when the emulsion paint is used, it has matched priming paint and top-coat paint, the priming paint can raise the adhesion of top-coat paint, and can resist alkali and mildew, and the top-coat paint has the functions of decoration, wear-resisting and protection. The special functions and functions of the paint should be fully exerted during construction, and the action that only finishing paint is used and primer paint is not used is forbidden;

the latex paint construction process flow comprises the following steps: cleaning dust, coating primer on a roller (brush), polishing wall paste, polishing, protecting finished products, and spraying (or brushing) finish;

b, emulsion paint construction is carried out on 1 bottom and 2 surfaces. Before brushing, the construction site is cleaned comprehensively at one time, and floating ash on a ceiling and a wall vertical surface is removed for brushing construction:

the primer roller (brush) coating operation step is that latex paint is poured into a clean empty barrel, a proper amount of clear water is added, then the latex paint is poured and stirred, the water adding amount is controlled to be between 10% and 30% according to the manufacturer specification, construction season and construction process, generally, the water adding amount in winter or spraying is preferably 10% as the lower limit, and the water adding amount in summer or roller coating is preferably 30% as the upper limit, and the latex paint is fully stirred and then filtered by a filter screen (bucket) for later use. During construction, brushing the internal and external corners with wool, and then brushing the fine-hair rollers in a criss-cross and comprehensive manner without roller leakage and brush leakage; after the primer was roll coated, 1 additional batch of plaster was applied to fill the small a holes to improve the finish and overall feel. The wall paste scraping method comprises stirring wall paste, calendering with plastic plate for 1 time from top to bottom and from left to right, and polishing with No. 800 abrasive paper;

brushing finish paint: when the finish paint is constructed by adopting a roller coating method, the operation method is basically the same as that of the primer, the finish paint in the 2 nd time is coated by using a wool brush for brush arrangement during roller coating, so that the finish paint surface layer formed finally is ensured to be smooth and fine, the wool brush is immediately used for brush arrangement in a longitudinal and transverse manner after the emulsion paint roller is coated on the back of a wall, the action is fast, and the finish paint is directly discharged when hands are folded;

and (3) spraying finish paint: the machine spraying construction adopts high-pressure airless spraying with water of 10-15%, the method is easy to form a film, has fine and smooth texture and high working efficiency, and indoor finished products, semi-finished products, original doors, windows and the like must be effectively protected by a plastic film before spraying. During spraying, the gesture and the spraying (flow) amount should be kept stable, and the border coverage is uniform from top to bottom and from left to right. And (3) after the spraying for the 1 st time, checking the overall spraying condition, checking whether the surface is not problematic, and spraying for the 2 nd time after the surface is dried. The spraying quality requirements are that the paint film is uniform without penetrating bottom, no flow cone and smooth surface layer.

If the latex paint is colored, the color plate should be selected according to the design and the requirement of the owner, and the color plate should be signed and confirmed by the owner and then color-adjusted by a computer. After color mixing, the light color latex paint can be properly mixed with water according to the specific construction conditions, the water mixing amount is controlled to be within 20 percent, the dark color latex paint can not be mixed with water, the color difference is prevented, the color latex paint needs to be uniformly stirred before use, and the construction can be carried out after the color latex paint is filtered by a filter screen (hopper). The construction method refers to the similar process, and when the local part is the color emulsion paint, the construction method is allowed to use a roller coating or brush coating method.
