Renovation: 17 things to watch when choosing paint

Construction sequence:

1. Remove dust and dirt on the surface of wooden products and lines (wood base).

2. Trimming the burrs on the surface of the wood substrate, lifting the flaws, etc., and polishing with a sand leather to make the corners neat.

3. Use oily putty (or transparent putty) to scrape, polish, refill and putty after putty (when using varnish, first make up brown eyes, nail holes, and do local color repair work).

4. Apply the paint over the first pass, refill the putty, remove the surface dust after polishing.

5. Apply the second pass of the paint. After polishing, remove the surface dust and perform water milling with the sand skin to repair the hanging oil.

6. Apply the third pass of paint until the desired result is achieved.

Construction methods: brush, roller, and spray have different lengths, and they should be taken separately.

The roller coating is suitable for large-area construction and is more efficient than brushing, but it will have a fish-like skin effect. This method of construction is unpopular for those who do not like pockmarks. Moreover, roller coating costs nearly 20% more material than brushing, artificially increasing the cost.

Brush painting is manual brushing and is a commonly used construction method. The advantage of the brush coating method is that it saves paint, the tool is simple, the construction is convenient, it is easy to grasp, the flexibility is strong and the adaptability to the paint variety is also strong, and it can be used for general paints.

However, the disadvantage of the brush coating method is that the manual operation is labor-intensive and inefficient, and it is not suitable for quick-drying paints. If the operation is unskilled and the action is not rapid, the paint film will produce brush marks, sag, and uneven brushing defects. .

Spraying is divided into two types, one is air spraying and the other is high pressure airless spraying.

Aerated spray leaves a lot of air bubbles on the wall. Although the construction speed is fast, the effect will be poor. It is not recommended for indoor use.

High-pressure airless spraying has just begun to become popular in China in recent years, but in foreign countries, high-pressure airless spraying of interior and exterior latex paints has long been widely used. The specific construction method is to use a special high-pressure airless sprayer to deliver the high-pressure paint through the high-pressure hose to the spray gun and release the pressure through the spray gun to form the atomization, thereby forming a smooth and dense coating on the wall surface.

Identification of construction quality tips

The simplest and most practical method is to use a flashlight to shine along the wall. Under strong flat rays, any cracks or bumps are visible at a glance.

buy:

Do not blindly pursue the performance of more products to buy a brand with a certain reputation, in order to prevent some unscrupulous construction units, "the civet cat for Prince Edward", the best consumers can think of the construction master asked after their own purchase. At present, there are many types of coatings in the paint market. There are also many kinds of business performance concepts. Consumers must pay attention to their own actual construction conditions to choose, and they should not blindly pursue performance-rich products.
