How to make melamine coatings, the whole process of asking for heroic instructions

Imitation porcelain is a relatively low-end wall coating (1) the requirements of the base layer The surface of the base must be firm and free of looseness, peeling, brightening, chalking and other phenomena; The soil, dust, oil, sundries and other dirt on the surface of the base must be washed and removed, the moisture content of the base layer is 10% and the pH value is 10, the surface of the base layer should be smooth, and the yin and yang angles and corners should be dense and distinct. Base treatment Any paint should be treated with a base layer before being painted, but for different decoration grades. Different base layers and different use environments require different base treatment processes and materials used in base treatment.

1) For the large formwork concrete wall with a very flat surface, the oil stain left by the coating of the separator should be clear first. When the oil is removed and the wall is dry, putty is inserted to eliminate the water bubbles. (2) The traditional white plaster wall is leveled with putty and then sanded with sandpaper to avoid damaging the original base layer.

3) Drywall. The surface of the wood plywood needs some special treatment, because the base layer expands and contracts with the change of temperature, which will cause the coating to crack. It is necessary to use white plain cloth or kraft paper caulking tape to bond the seams with polyvinyl acetate emulsion.

Then use putty batch insertion leveling, and finally large area batch putty embedding. (4) The renovation of the old wall should first remove the floating ash and remove the sand, warp skin, oil stains and other parts. The wall is cleaned and then putty is inserted, and finally polished and smoothed.

2) Construction preparation 1material preparation; Tool Preparation 2Material factory certificate, license and other must-haves.

3.Operator ID. 4.

Construction tools: grassroots treatment tools include scrapers and cleaning tools; Brushing tools include brushes and knives 5Labor protection supplies include gloves, work clothes, etc.; Protective tools include long cloths, etc.

1. The base treatment should be smooth, free of dust and oil, and the surface should be dry. Melamine coating construction 2, coating the bottom coating, the first first coating of diluted coating, drying, and then coating twice, drying time 2 24h. Then scrape 1 3 times with the putty prepared by the primer, with an interval of 24 48h, and polish it with 1 abrasive cloth after drying.

Melamine paint construction 3, apply the surface layer paint 2 3 times, and maintain it for 3 days after drying.

1.Preparation: Clean the surface to ensure that the surface is dry, smooth, free of oil and impurities.

2.Stirring the paint: Stir the paint in the paint bucket well to avoid sedimentation.

4.Brush melamine paint: Use a brush or roller to evenly apply the melamine paint on the surface, paying attention to the consistent direction of the brush to avoid brush marks.

5.Secondary coating: After the first coat of paint has dried, a second coat of paint is applied to increase the thickness and gloss of the coating.

6.Wait for drying: Once the paint is dry, carry out the necessary trimming and sanding to achieve the best results.

7.Cleaning tools: After the construction is completed, clean the painting tools in time to avoid the waste caused by the drying of the paint.

8.Precautions: During the construction process, it is necessary to pay attention to ventilation to avoid damage to the human body caused by the coating.

At the same time, it is necessary to avoid the paint from touching the eyes, ** and other parts, and if you are not careful, you should clean it in time.
