The scrub resistance is a comprehensive performance index of the paint film. It not only reflects how easy the coating is to clean, but also represents its water resistance, alkali resistance and the toughness of the paint film. VOC and formaldehyde content are environmental and health indicators; the lower these values, the better the environmental performance of the coating.
Smell the coating you intend to buy. The lighter the odor, the better. Any pungent smell or overly strong fragrance should arouse suspicion. Genuine low-odor paint only has a faint natural paint smell, instead of masking odor with added essence. High-quality paint has zero or extremely low VOC, resulting in very slight odor.
Check and touch the paint sample to judge the quality of the paint film. Good latex paint forms a dense, delicate and glossy film; inferior latex paint usually feels rough and coarse.
Brand stores generally display product samples. You can test the paint film performance through different methods, such as scrub resistance and stain resistance. If some performance indicators are not marked on the product, ask the sales staff to give a clear and responsible explanation.
If possible, it is best to test the paint personally.
Open the paint bucket and stir the paint with a stick to check for lumps. Lumps mean the paint has deteriorated.
Lift some paint with the stick and watch how it flows down. If it flows down in a continuous filament instead of breaking into pieces, the paint has good fluidity and decorative effect.
Pinch a little paint with your fingers to feel its fineness — the finer the texture, the better. If a scraper is available, use it to test the fineness; finer texture indicates better quality.
