Drywall Basics
Drywall repair is a graduated skill — small nail holes require only minutes and basic materials; large damaged areas require structural backing, proper compound technique, and feathering to blend seamlessly with surrounding surfaces.
Small nail holes (3-6mm) can be filled with lightweight spackling compound applied with a putty knife, smoothed flush, allowed to dry, sanded lightly, and primed before painting. The entire process takes 15 minutes plus drying time.
Installation Process
Larger holes (50-100mm) require backing support before filling. The California patch technique uses a piece of drywall with paper facing extending 50mm beyond the patch, scored and snapped, then adhered with the paper facing providing structure for compound application.
Cut-patch repair for holes 100mm and larger involves cutting a clean rectangular hole, installing wood backing (horizontal cleats inside the wall at the top and bottom of the opening), and installing a matching drywall patch fastened to the backing.
Finishing for a Flawless Result
Compound application technique determines whether patches blend visibly or not. The key is feathering — extending each successive compound coat further than the last. A properly feathered patch is invisible under paint because the transition is gradual rather than abrupt.
Texture matching is the most challenging element of drywall repair in textured rooms. Spray texture, skip trowel, knockdown, and orange peel textures each require specific tools and technique to match. Practice on cardboard before applying to the wall.
Priming repaired areas before painting is non-negotiable. Joint compound absorbs paint differently than surrounding wall surfaces — painting without priming produces a flat, different-looking area that makes repairs visible even under good colour coverage.
