When renovating old furniture, choosing the right paintbrush and using the appropriate techniques are crucial for achieving the desired coating effect. Here are some suggestions:
First, the selection of paintbrushes
Choose a brush according to the type of paint
Water-based paint: Water-based paint is environmentally friendly, dries quickly and is suitable for brushes with synthetic fiber bristles. Synthetic fiber brushes have excellent water absorption, which can evenly absorb and release water-based paint, making the brushing effect smoother.
Oil-based paint: Oil-based paint has strong adhesion and dries slowly. It is suitable for using natural bristle brushes, such as pig bristle brushes. Natural bristle brushes can better absorb oil-based paint, making the brushing effect more full.
Mixed paint and nitrocellulose paint: These paints have good fluidity and are suitable for use with medium-hardness brushes, such as horsehair brushes or mixed fiber brushes, which can not only ensure the painting effect but also improve the construction efficiency.
Choose the brush according to the area to be painted
For large flat areas such as furniture panels and tabletops, it is suitable to use wide roller brushes or flat large brushes to improve the painting efficiency.
Corners and grooves: such as the legs and feet of furniture, the edges of drawers, etc., are suitable for using small round-tipped brushes or pointed brushes, which can better reach the detailed areas.
Choose high-quality brushes
Bristle quality: The bristles should be soft, elastic and not prone to shedding. High-quality bristles can evenly dip into the paint and apply it smoothly without any hindrance.
Brush handle design: The brush handle should be sturdy, comfortable to hold, ergonomically designed, and convenient for long-term holding and operation.
Brand reputation: Choosing products from well-known brands ensures quality and offers more comprehensive after-sales service.
Second, the usage skills of paintbrushes
Preparations before painting
Clean the surface of furniture: Use sandpaper to remove old paint and impurities, making the surface of the furniture smooth and flat.
Stir the paint: Stir the paint thoroughly to ensure uniform color and avoid sedimentation or lumps.
Soak the brush: Soak the brush in the paint for a while to allow the bristles to fully absorb the paint.
Techniques for painting
Dip the paint evenly: Do not dip too much paint to avoid flowing or dripping. Excess paint can be gently scraped off the edge of the container.
Apply along the grain: For wooden furniture, apply along the grain direction of the wood to make the painting effect more natural.
Thin application in multiple layers: Each application should be thin and even. Wait until the previous layer of paint is completely dry before applying the next layer. Multi-layer coating can enhance the thickness and gloss of the paint film.
Avoid brush marks: When applying, apply even force and at a moderate speed to prevent brush marks or missed areas.
Protect surrounding items: Use masking tape or plastic sheeting to cover the surrounding items and the ground to prevent paint splashing and causing pollution.
Post-painting treatment
Clean the brush: Clean the brush promptly after use to prevent the paint from drying out and damaging the bristles. It can be washed with warm water and soap, and then dried for storage.
Ventilation and drying: Place the painted furniture in a well-ventilated area to dry, avoiding direct sunlight or high-temperature baking.
Inspection and repair: After drying, check the brushing effect. If there are any missed areas or uneven areas, repair them in time.
Third, precautions
Safe construction
Personal protection: Gloves, masks and protective glasses should be worn during construction to prevent paint from splashing onto the skin and eyes.
Ventilation and air exchange: During construction, ensure good indoor ventilation to prevent the accumulation of paint odors.
Choose environmentally friendly paint
Water-based paint: Water-based paint is environmentally friendly, has no pungent smell, and is harmless to the environment and human health.
Low-voc paint: Choose paint with a low content of volatile organic compounds (VOC) to reduce pollution to indoor air.
Reasonable budget
Formulate a reasonable budget based on the material, size and renovation requirements of the furniture, and select the appropriate paint and tools.
