First, buy
1. Look at the weight: lift the paint bucket and shake it. If there is a crackling sound, it means that the weight is severely lacking, and there is no shortage of weight, or the viscosity is too low. Formal manufacturers of real materials, shaking almost no sound.
2. To make an estimate of the amount to be used, one purchase should be made at the time of purchase in order to avoid chromatic aberration in the purchased paints.
3. Choose the same brand: primer and topcoat are best to use the same brand or matching paint to prevent adverse reaction between primer and topcoat.
Second, the paint construction sequence:
1. Remove dust and dirt from the surface of wooden products and lines (wood base).
2. Trimming the burrs on the surface of the wood substrate, lifting the defects, etc., polishing with sand, and neat corners.
3. With oily putty (or transparent putty) for scraping, polishing, polishing after putty repair (when using varnish, first make up brown eyes, nail holes, and make local color correction work).
4. Apply the paint over the first pass, refill the putty, remove the dust on the surface after polishing.
5. Apply paint a second time. After polishing, remove dust from the surface and perform water-milling with water-sanding to repair the hanging oil.
6. Apply the paint three times until it reaches the desired effect.
Third, the paint construction sequence
1. Wall patch: In order to prevent cracks on the wall, non-load-bearing walls must be patched.
2. Wall lining: Wall lining is an alternative to 821 putty and is a material that must be used for the wall base.
3. Primer: The primer has a damp-proof and mildew-proof effect. Be sure to brush the primer after brushing the primer.
4. Color paint: When choosing the paint color according to the color card of the building materials market, it is better to choose a lighter color than the color card.
5. Spraying: The effect of spraying is better than that of worker's hand brush, but it is more expensive than material.
Fourth, paint paint construction points
(a) fire safety knowledge
General paints and paints are flammable and explosive chemicals. Especially during the painting construction, a large amount of combustible gas can evaporate into the air, and it is very prone to burning or explosion accidents. Therefore, in the construction of coatings, the following issues must be noted:
1. Ensure air circulation and prevent the accumulation of solvent vapors;
2. Prohibit any open flame, prohibit the use of open fire to bake or heat paint;
3. It is forbidden to wear chemical fiber clothing to the construction site to prevent static electricity sparks;
4. It is forbidden to perform other operations on the paint construction site, especially the operation of iron strikes and violent friction of articles.
(2) Safety knowledge
In the construction of paint must pay attention to safety protection
1. It is forbidden to enter the mouth with paint. In the eyes, problems must be washed with clean water and sent to the hospital for treatment;
2. It is forbidden to drink water or diet at the painting construction site;
3. Ensure air circulation and prevent the accumulation of solvent vapors;
4. If a large amount of inhalation of solvent vapor occurs and symptoms of discomfort occur, they must quickly leave the scene and breathe fresh air. After the symptoms have disappeared, the construction can be resumed.
(3) Knowledge of work safety at height
When working at heights, necessary safety precautions must be taken. When carrying out paint construction on construction sites, helmets must be worn.
(4) Construction tips
1. Before construction, the surface must be clean, dry, and fully cured, except for dust, mildew and peeling paint. Fill nail holes, cracks, and smooth the surface to remove dust;
2. Cover surfaces that do not require painting. Paints should be mixed well before use and used according to the packing instructions;
3. First brush corners, window frames and other parts, and then brush a large area of ​​the wall;
4. Brushes, rollers, etc. can be used. After each brushing, it needs to be dried for a certain period of time. Under normal circumstances, the water-based coating takes 4-6 hours, and the oil-based coating takes 24 hours to be applied the second time.
5. After brushing is completed, clean the brushes, rollers, etc. with solvent, and dispose of excess paint.
6. The weathering requirements for exterior latex paint construction are that the air temperature is greater than 5°C and the humidity is less than 85%. In rainy days and windy days, construction should be avoided, otherwise the paint film will be washed away by rain or flushed.
