Because paint has the advantages of strong colorability and low price, it has become the first choice for floor decoration in some public places. The painted floor looks smooth and beautiful, no worse than the tile floor. There are many things to pay attention to when painting the floor. When painting the floor, everyone should follow certain methods and pay attention to some things, so as to make the floor more beautiful and pleasing to the eye. This article will introduce you to the steps and precautions for painting the floor.

Steps for painting the floor

1. Preparation

Paste color separation paper to protect the joints between doors, window frames, furniture and paint. The finished wooden cabinets, partitions and other furniture should be sealed with newspapers to prevent paint drippings from staining the furniture.

　2. Color mixing

For floors with color requirements, the area should be accurately calculated in advance and the paint should be mixed evenly at one time. Then apply primer, which can prevent moisture on the wall, make the color of the topcoat even, and prevent water stains caused by acid wood board.

3. Roller coating construction

The floor must be painted at least twice. 5% to 10% water can be added to the first coat to facilitate absorption by the wall. The second coat should be painted There is no need to add water to the paint, and there is a certain interval between the first coat and the paint. When rolling, you need to use both thick and thin roller brushes at the same time. The thick roller brush goes first, and the thin roller brush follows immediately. Use a coarse roller to apply the paint evenly to the wall, then use a fine roller to paint the areas where the coarse roller has brushed, and paint again to make the paint on the wall finer and create the desired pattern.

4. Brush construction

Use a brush to touch up the missed paint on the sides and corners of the wall.

5. Polish the ground

After the paint on the ground dries, use sandpaper to polish the ground to reduce brush marks and make the ground smoother. When sanding, be sure to feel the smoothness of the ground with your hands from time to time in order to judge where it needs to be sanded. It should be noted that when sanding, try to use finer sandpaper. Generally, putty with a soft texture (such as 821) uses No. 400~500 sandpaper, and putty with a harder texture (such as wall lining, Yiguaping) uses No. 360~400. The number is better. After sanding, clean the floor thoroughly.

6. Cleaning and inspection

Clean up the traces of paint on the skirting and other places, check whether the color of the wall meets the design requirements, and whether the color of the painted surface is consistent to prevent There are quality defects such as see-through bottom, missing paint, peeling powder, bubbling, color bite, and dripping.

Precautions for painting

1. Try not to add water to dark paint, otherwise color difference will easily occur; it is best to complete the painting at one time, otherwise color difference will easily occur.

2. Do not paint in humid weather or winter, otherwise it will affect the overall construction quality and the paint will not dry easily.

3. Pay attention to indoor ventilation and heat dissipation, and wait until the paint and coating are completely dry before polishing.

4. After finishing brushing and waiting to dry, soak the brush in water and check whether there are bubbles in the brushed area. If there are bubbles, pop them immediately.

5. When the brush is dipped in paint, the part of the bristles immersed in the paint should not exceed half the length of the bristles. If the roots of the bristles are stained with paint, the paint brush will be deformed and the service life of the paint brush will be shortened.

6. When performing oil opening and horizontal oiling operations, the paint brush should be kept vertical as much as possible and the belly of the bristles should be used to apply paint. When performing oiling and modification operations, lay the paint brush flat and brush gently with the front end of the bristles.

7. Pay attention to the direction of the paint brush. When painting vertical surfaces, the last brush should be applied from top to bottom. When painting horizontal surfaces, the last coat should be applied in the direction of the light.

Through the above introduction, we have a general understanding of the steps and precautions for painting the floor. From this we can see that the process of painting the floor is actually not complicated, but there are many precautions in this process. Everyone should focus on understanding these precautions and pay attention to them during the construction process. If the paint is not smoothed or splashed elsewhere, it will be more difficult to take care of. Referring to the above introduction, I believe everyone can paint their floors with a beautiful paint surface.
