Wall acceptance is one of the most important items of home decoration acceptance. You must be careful when accepting, otherwise you will find problems after you check in, which will be very troublesome. The following is a detailed introduction to the acceptance points of wall painting, wall tiles and wallpaper

I. meticulous and flat paint surface wall painting acceptance

whether the effect of wall painting is meticulous and flat, without falling off and mildew mainly depends on the quality of paint and construction technology, especially the treatment technology of wall base. Therefore, the acceptance of wall paint should start from the base, and it should be accepted once before painting, and then again after painting

whether the effect of wall painting is meticulous and flat

acceptance of wall base course: base course treatment is the key link to ensure the construction quality, in which ensuring that the wall is completely dry is the most basic condition, because the mortar made of cement as bonding material is strongly alkaline before hardening, so the emulsion paint must be anti alkaline at this time. After the cement mortar hardens, the alkaline value decreases significantly, and then the emulsion paint can be applied. The drying time varies with climatic conditions, and should generally be kept for more than 10 days. The wall must be flat, and the putty should be applied at least twice. If it still fails to meet the standard, it should be scraped to meet the standard requirements

acceptance of wall base

acceptance of wall paint film: the variety and color of materials used for latex paint brushing meet the design requirements, and the color of the brushing surface is consistent, and there are no quality defects such as penetrating the ground, missing brushing, powder falling, alkali peeling, peeling, biting and so on. When using the spray gun for spraying, the spray point shall be dense and uniform, and there shall be no skin connection, no sagging, the paint film shall be smooth and free of powder when touched by hand, and the doors, windows, lamps, furniture, etc. shall be clean without paint traces

acceptance points and standards:

1. Stand 1.5m away from the wall and observe, without sand holes, biting, sagging, color difference, bottom penetration, etc

2. The coating shall be uniform, firmly bonded, and shall not be missed, exposed, peeled and rusted

paint surface quality inspection

precautions for paint Construction: roll coating is used in large areas, and hand brushing is used in the corners, which not only improves the brushing efficiency, but also ensures the brushing quality. During construction, the emulsion paint must be fully stirred before use. When matching colors, you should choose alkali resistant and sun resistant color paste to mix with the paint liquid, and it is forbidden to mix dry color powder with the paint liquid. The emulsion paint with color paste shall be stirred for at least 5 minutes to make the color uniform before construction

II. Smooth and tidy brick wall tiles acceptance points

the wall decoration of kitchen and bathroom is mainly based on tile paving, and the wall tiles should be flat, solid and tidy. There are several steps and standards for the acceptance of the construction of wall tiles

1. Hollowing and falling off: the main reasons are insufficient bonding materials, insufficient brick soaking and unclean base treatment. During construction, the sleeve tiles must be clean, soaked for not less than 2 hours, and the bonding thickness should be controlled between 7-10 mm, not too thick or too thin. When pasting, the face brick and the bottom layer should be pasted tightly, which can be gently knocked with a wooden hammer. When hollowing occurs, the wall tiles should be removed, the original bonding mortar should be removed, and the cement mortar accounting for 37% of the total volume should be used to repair

2. Color change: in addition to the poor quality of ceramic tiles and too thin axial surface, improper operation methods are also important factors. Materials shall be strictly selected during construction, and clean water shall be used for soaking sleeve face bricks. The pasted cement mortar should use pure sand and cement. During operation, the residual mortar on the brick surface shall be cleaned at any time. If the color changes greatly, the wall tiles should be updated

3. Uneven joints: the main reasons are differences in brick specifications and improper construction. During construction, face bricks shall be carefully selected, and those of the same size shall be grouped together for use on one wall. The standard points must be pasted, and the standard points should be subject to the guiding rule. After each line is pasted, it should be checked horizontally and vertically with the guiding rule in time, and corrected in time. If the joint exceeds the allowable error, the wall tiles should be removed in time for rework

III. key points of smooth and comfortable paper wallpaper paving and acceptance

wallpaper paving is a wall decoration method loved by many consumers, because it has the advantages of convenient construction, easy replacement, and many choices of designs and colors. The most important thing for the wall with wallpaper is to achieve several standards, such as smoothness, fitting, and no gap at the joint of patterns

1. The surface of the mounted wallpaper and wall cloth should be flat, the color should be consistent, and there should be no ripples, bubbles, cracks, folds and spots. There should be no glue marks when squinting

2. Wallpaper and wall cloth should be closely connected with various decorative lines and equipment wire boxes

3. The edges of wallpaper and wall cloth should be straight and tidy without paper wool and flying thorns

4. The internal corners of wallpaper and wall cloth should be lapped smoothly, and there should be no joints at the external corners

wallpaper acceptance method: after the wallpaper construction is completed, stand 1.5 meters away and observe that the paper has no obvious joints or is not obvious; The flowers are neat; The mounting shall be firm without seams, hollowing, warping, wrinkles, stains, burrs, glue marks and indentation; There is no joint at the internal and external corners

there is another situation that needs to be noticed. Because of the pattern or color of some wallpapers, you can see the seams against the strong light line, which is unavoidable. Light colored or coarse textured styles basically do not have the above problems from the visual effect

precautions for laying Wallpaper: when starting to paste wallpaper, for the joint, the two sides of the adjacent wallpaper are squeezed together to make them coincide, and then the joint is pressed with a scraper, and the extruded glue is cleaned. After the wallpaper is pasted, use a scraper to roll the pasted wallpaper from top to bottom. Wallpaper pavement is prone to problems such as glue opening, uneven patchwork, and yellowing of joints

wallpaper maintenance skills:

to deal with the mildew of wallpaper, you can first wipe the wall with a dry cloth, then add a half bottle cap of 84 disinfectant into 4 paper cups of water, or use a diluted professional wallpaper cleaner to wipe the wall with mildew after mixing it evenly

moisture proof maintenance of wallpaper

if the wallpaper is warped due to moisture, you can paste it with professional wallpaper glue and press it with flat objects, such as books, such as table tennis rackets. If it is bubbling, you can use a sewing needle to pierce a small hole in the bubbling position on the surface of the wallpaper to release gas, take an appropriate amount of adhesive and put it into the eye of the needle to stick, and finally press it with a flat book to dry

if the edge of the wallpaper is warped due to dryness, if not, use a syringe to inject glue into the edge of the wallpaper crack and try to re stick the wallpaper. Or use the adhesive powder pasted with wallpaper to wipe it on the curling part, smooth the warping part, blow it with a hair dryer for about 10 seconds, and then press it with your hand until it sticks firmly, and then blow it with a hair dryer until it is dry. When repairing, pay attention to first determine whether there are problems in the base course. Be sure to extend the repair, and extend the repair range around the crack
