When using paint brushes, you need to pay attention to the following points to ensure construction safety and effect:

First, construction environment and safety measures
Maintain air circulation: the construction site should maintain good ventilation conditions to avoid harmful gas accumulation, affecting the health of construction personnel.
No fire: There can be no fire on the construction site, no smoking and welding construction, in order to prevent fire.
Personal protection: When using paint brushes, wear protective equipment such as goggles, masks and gloves to avoid direct contact with skin and eyes.
Second, the use and maintenance of paint brushes
Choose the right paint brush: Choose the right paint brush according to the construction needs, considering the material, density and comfort of the brush handle.
Correctly dipping paint: When dipping paint, the part of the bristles immersed in the paint should not exceed half of the hair length, so as to avoid excessive paint on the root of the bristles and deformation.
Uniform brushing: When brushing should be uniform force, along the texture of the wood or wall, to avoid bubbles and brush marks.
Timely cleaning: After each painting, the paint brush should be cleaned with water or solvent in time to remove residual paint and avoid dry joints affecting the next use. After cleaning, the brush can be soaked in water, and then put away after drying.
Proper storage: Paint brushes should be stored in a dry and ventilated place, away from direct sunlight and damp environment, to prevent deformation and mold of the bristles.
Third, construction skills and precautions
Surface treatment: The construction surface should be cleaned and treated before brushing to ensure that the surface is smooth and free of oil and impurities to enhance the adhesion of the paint.
Primer treatment: Apply primer as needed to improve the adhesion and hiding power of the top paint.
Avoid chromatic aberration: Try not to dilute the dark paint with water to avoid chromatic aberration. Painting is best done at one time to avoid color difference caused by multiple brushes.
Pay attention to weather conditions: rainy or wet weather is not suitable for construction, so as not to affect the drying and quality of paint. At the same time, avoid construction under low temperature conditions in winter to prevent the paint from drying easily.
Ventilation and heat dissipation: During construction, attention should be paid to indoor ventilation and heat dissipation to avoid uneven drying or cracking of the surface caused by excessive volatilization of the paint.
Check bubbles: During the brushing process, attention should be paid to check whether there are bubbles, if there are bubbles, it should be broken and repaired in time.
Fourth, other precautions
Estimated amount: The amount of paint required should be estimated before construction to avoid affecting the construction progress and quality.
Batch construction: For large area construction, it should be painted in batches, and after each batch of painting, the paint should be waited for completely dry before the next batch of construction.
Protection of the finished product: Measures should be taken to protect the finished product surface from dust or damage.
To sum up, when using paint brushes, it is necessary to pay attention to the construction environment, the use and maintenance of paint brushes, construction skills and precautions, and other aspects to ensure construction safety and effect.
