Common paint budget mistakes
Avoid these typical mistakes when estimating painting costs.
Overestimating paint coverage
Many underestimate the amount of paint needed because they assume the paint covers better. Especially changing a dark colour to a light one often requires 3 coats. Always reserve 5–10% extra paint for touch-ups and repairs.
Forgetting preparation work
The cheapest paint is not the cheapest solution if the walls need filling, sanding or priming. Surfaces in poor condition may require significantly more work and material – this can even double the total cost.
Choosing cheap paint
Cheap paint covers worse and wears out faster. Quality paint may cost 2–3 times more, but often covers with fewer coats and lasts years longer. In the long run, quality paint is more affordable.
Underestimating time and effort
Painting sounds easy, but a professional finish requires careful masking, protection and multiple work stages. DIY painting takes time and can leave visible marks that a professional would avoid.
Ignoring the household deduction
Painting work qualifies for the household deduction, which significantly reduces the cost. In 2026 the deduction is 60% of the labour cost, up to €2,550 per person. Calculate your savings with the household deduction calculator.
