Prep walls, floors, and ceilings for painting and repairs with surface preparation materials from Reno Depot. Protect switch plates and baseboards from paint and leave clean edges behind with the help of masking tape and paper. If a wall has holes, make it flat and even before painting with an application of spackle. Make other quick and easy surface repairs using wood filler and repair kits that match the natural colour of the existing wood. Sand down these compounds when dry and then paint with confidence.
