When painting wooden furniture, some skills need to be mastered when using a paintbrush to ensure a smooth and even paint surface effect. Here are some key painting tips:
First, preparatory work
Choose the appropriate paint
According to the material and application of wooden furniture, choose the appropriate type of paint, such as oil-based wood paint, water-based wood paint, etc. Water-based wood coatings are environmentally friendly, but they are relatively expensive. Oil-based wood lacquer has strong adhesion, but it has a strong smell.
Substrate treatment
Before painting, use sandpaper to smooth the surface of the wooden furniture, removing stains, dust and blemishes on the surface.
Ensure that the surface of wooden furniture is dry, free of oil and water to enhance the adhesion of the paint.
Mix the paint
Mix the paint according to the instructions, and pay attention to controlling the consistency and dilution ratio of the paint. Water-based wood coatings can be directly diluted with water in proportion, while nitrocellulose lacquer and polyurethane paint require the addition of relevant curing agents and thinners.
Second, painting techniques
Hold the brush
Hold the handle of the paintbrush and control the force and direction of the brush with your thumb, index finger and middle finger.
The bristles should be kept at an appropriate Angle to the wooden surface, generally 30° to 45°, in order to better control the application of paint.
Dip in the paint
Gently dip the paintbrush into the paint to avoid excessive paint sticking to the bristles, which may cause dripping or sagging.
You can gently scrape off the excess paint along the edge of the paint can to make the amount of paint on the bristles moderate.
Painting sequence
Start painting from the edges of the wooden furniture and gradually transition to the middle part.
For large areas of wooden surfaces, the paint can be applied along the direction of the wood grain to better penetrate the wood.
Brushing force
When applying, the force should be moderate, avoiding being too heavy or too light. Excessive force will cause obvious brush marks, while too little force may result in uneven paint coverage.
Brushing speed
The brushing speed should be uniform and a stable rhythm should be maintained. Both too fast and too slow speeds may affect the painting effect.
Overlapping brushing
When applying the next coat of paint, it should overlap with the previous coat to ensure even application and avoid missed areas or uneven color.
Third, precautions
Environmental requirements
When painting, ensure good ventilation in the room and avoid painting in damp, hot or cold environments.
The temperature is best maintained at room temperature (15℃ to 30℃), and the humidity should not exceed 80%.
Avoid pollution
Before painting, protect the surrounding furniture and the floor with newspapers or plastic sheeting, etc., to prevent paint from splashing and causing pollution.
Timely cleaning
After using the paintbrush, it should be cleaned and dried in time for the next use.
Multi-layer coating
For wooden furniture that requires multiple layers of paint, wait until each layer of paint is completely dry before applying the next layer.
Detail handling
During the painting process, pay attention to painting the detailed parts of the wooden furniture (such as corners, carvings, etc.) to make the furniture more beautiful.
Avoid mixing different products
It is strictly prohibited to mix different products, especially brand products, to avoid reactions that may cause changes in the wood lacquer and fail to achieve the expected effect.
