Home decoration paint needs careful identification of construction quality

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. .

Construction sequence:

Remove dust and dirt from the surface of wooden products and lines (wood base). Trimming the burrs on the surface of the wood substrate, lifting the defects, etc., polishing with sand, and neat corners. 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).

Apply the paint over the first pass, refill the putty, remove the surface dust after polishing. Apply the paint a second time. After polishing, remove dust from the surface and apply water to the surface to repair the part of the oil. Apply the third pass of paint until the desired result is achieved.

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.

Identify the 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 many products to buy a brand with a certain reputation, in order to prevent some illegal construction units, "the civet cat for the Prince", 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.

Decoration paint points to a good safety quality:

In the construction of medium and dark latex paint, do not mix with water as much as possible, otherwise it is prone to chromatic aberration. Gypsum board seams should be bandaged. Walls have gaps where they are really cool cloths, and some of the original wall putties are best eradicated. , Or brush the glue once again, try to buy paints of well-known brands, decoration company recommended or recommended by the foreman as far as possible not to use, the weather is too humid, do not paint paint, paint, paint, etc. to be polished completely dry, The next paint must be done after the previous paint is dry. The paint on the metal surface must be rust-proof. The weather is too cold. The quality of the paint will be poor. When the door is painted, use a textured paper to cover the hinge and the door lock. , It is too hot to pay attention to ventilation. When wallpapering, it is necessary to brush oil on the wall. When affixing wallpaper, it is necessary to remove the panel of the switch and socket. The light and mercerized latex paint must be completed at one time. After installing the skirting board, use putty and latex paint to make up the seam. The frosted glass should be protected with newspapers.
