During home painting, many homeowners fall into common mistakes that lead to unsatisfactory results. Here are 11 frequent pitfalls and the correct approaches to avoid them.
Myth 1: The smoother the finished wall, the better. Important note: For latex paint walls applied with a roller, avoid aiming for an ultra-smooth surface. Roller-applied walls naturally show fine roller marks; this is normal. Forcing a perfectly smooth finish can damage the paint film.
Misconception 2: The more water you add to the paint, the better. Over-diluting results in a thin film, reduced coverage, and issues like uneven coloring or chalking. For most latex paints, do not exceed a dilution ratio of 10%-20%.
Misconception 3: Skipping primer is acceptable. Primer enhances topcoat adhesion, seals base alkalinity, and improves finish fullness; it is an essential step that cannot be omitted in any coating system.
Misconception 4: Cracks in walls can be patched casually. Proper crack repair requires removing loose material around the crack, filling it with joint compound, applying a crack-prevention tape, and then applying putty. Skipping these steps will cause the crack to reappear quickly.
Myth 5: Dark paint is harder to apply than light paint. In reality, both are applied using the same method; dark colors may simply require an extra coat for optimal coverage.
Myth 6: Construction cannot be done on rainy days. Work can proceed normally if the indoor temperature is above 5°C and relative humidity does not exceed 85%. However, ensure proper ventilation and allow sufficient drying time.
Misconception 7: More expensive paint is always better. Choose paint based on your specific needs, using different types for different areas rather than simply opting for the most expensive products.
Myth 8: More coats are better. Over-applying paint can create a film that is too thick, leading to cracking and peeling. Typically, one coat of primer and two coats of topcoat are sufficient.
Myth 9: Open windows immediately after painting. Avoid direct drafts on freshly painted walls, as rapid drying can cause cracking. Close windows and doors for 24 hours after application before ventilating the room.
Myth 10: Neglecting finished product protection. Before construction, cover floors, furniture, doors, and windows to prevent paint splatters from causing damage.
Mistake 11: Mixing colors yourself. Professional color matching requires specialized pigments and equipment; DIY mixing often leads to color mismatches and fading. We recommend using our brand's computerized color-matching service.
