Drywall & Plaster Repair

What this certification means

Drywall & Plaster Repair covers the single most requested handyman job in the country. It proves you can cut, hang, tape, mud, texture, and blend a repair so the customer cannot find it once the paint dries.

• Joint compound families — taping, topping, all-purpose, and setting-type hot mud
• Coat sequence, feathering, and sanding without gouging
• Corner bead repair: metal, vinyl, and paper-faced
• Texture matching — knockdown, orange peel, skip trowel, smooth level 5
• Plaster and lath repair in older homes
