Painting a Room Like a Professional
From surface preparation and primer through to cutting in, rolling, and clean-up — follow this guide for a smooth, long-lasting interior paint finish that looks like it was done by a professional decorator.
Prepare the Room
Remove furniture or move it to the centre and cover with drop cloths. Remove switch plates, outlet covers, and light fittings. Lay canvas drop sheets on the floor — they grip better than plastic and absorb splashes.
Repair Walls and Ceiling
Fill nail holes and cracks with lightweight filler. Sand flush when dry. For larger cracks or damaged plasterboard seams, apply two coats of joint compound, feathering each pass wider than the last.
Clean Walls and Prime
Grease and grime prevent paint adhesion — wipe walls with a sugar-soap solution before painting. Apply primer to bare patches, repaired spots, and any dark or glossy surfaces you're painting over.
Tape and Prepare Edges
Apply painter's tape along skirting boards, window frames, door architraves, and the ceiling-wall junction (if painting walls only). Press the tape edge firmly to prevent bleed-through.
Cut In Along Edges
Use a quality 65 mm angled sash brush to paint a 75–100 mm band along all edges, corners, and areas the roller can't reach. Cutting in first means your roller coat can overlap without worrying about edges.
Roll the Walls
Load a 9-inch roller with a medium-nap sleeve. Apply paint in a W or M pattern and then fill without lifting the roller to avoid stipple marks. Maintain a wet edge at all times.
Second Coat, Clean Up, and Reinstall
Once the first coat is dry, apply a second coat using the same cut-in then roll technique. Remove tape while the final coat is still slightly tacky for the cleanest edge. Clean brushes and rollers promptly.
