Tips for a Perfect Paint Job
Follow these best practices to ensure your calculations and final results are flawless.
Measure Twice, Buy Once
Double-check your wall measurements. For rooms with different heights, measure each wall and add the lengths together.
Don't Skip the Primer
Using a primer, especially on new or dark walls, ensures better paint adhesion and a more vibrant, even final color.
Consider Surface Texture
Rough or textured walls absorb more paint. For highly textured surfaces, consider increasing the waste factor to 15-20%.
