Preparation Is Everything

Remove furniture, cover with drop cloths. Remove outlet covers. Fill holes. Clean walls. Apply painter tape. Good prep is 80% of the job.

Choosing the Right Paint

Flat for ceilings. Eggshell for bedrooms and living rooms. Satin for kitchens and bathrooms. Semi-gloss for trim.

The Cutting-In Technique

Use a 2.5-inch angled brush along edges. Work in 3โ€“4 foot sections, then immediately roll the adjacent area while the edge is still wet.

Rolling Technique

Roll in a W pattern to distribute paint, then smooth with even vertical strokes. Two thin coats always look better than one thick coat.

Pro Tips

โœ“One gallon covers approximately 350โ€“400 square feet
โœ“Paint in order: ceiling first, walls second, trim last
โœ“Remove painter tape while the final coat is still slightly tacky
