Mistakes to Avoid

Most bad experiences with interior painting aren't down to the paint itself, but to a handful of small process mistakes that seem trivial at the time yet leave visible traces in the final result.

The most common mistake is skipping primerPrimerThe thin first coat that goes on before the main material. It binds dust, seals the pores and helps paint or waterproofing stick firmly. on the logic of "I'll just add a third coat of paint instead." In practice, paint applied without primer gets absorbed unevenly by the surface, leaving some areas looking flatter or darker than others even after two or three coats — a problem the right primer would have prevented from the start, at a lower total cost.

A second common mistake is applying the second coat before the first has fully dried. The result is visible roller marks, an uneven texture, and in extreme cases, chunks of the first coat lifting off along with the second. The drying time printed on the tin is a good starting point, but in high humidity or low temperatures it can take noticeably longer.

Finally, using cheap masking tape is a mistake that looks trivial but costs a lot of touch-up time: poor adhesion lets paint bleed under the tape's edge, creating jagged, uneven lines instead of clean, straight ones. A good-quality tape costs only slightly more but saves significant time on final touch-ups.
