Prevent Concrete & Drywall Repairs Showing Through the Finish Coat!
January 22, 2018
If you don’t take the proper steps to provide a uniform surface for the finish coat, this could lead to a costly error where the entire wall needs to be repainted, adding unnecessary hours to a job. A classic case of more haste, less speed. Avoid delays by doing it right first time!
Its common especially in residential renovations, both homes and rental properties, to have to fill unsightly holes that were once used to hang wall decorations. These need to be repaired when readying for a new tenant or reimagining rooms. Depending on the size of the hole, fillers such as caulk, putty and joint compounds are often used. When dry these materials have a different structure to the surrounding wall, being more or less porous. If improperly primed and painted, the patched area will ‘show through’ the final coat – a condition that is also referred to as ‘flashing’.
To prevent flashing
- After patching allow compounds and fillers to dry fully.
- Spot prime patched area with Super Grip Premium Problem-Solving Primer and allow to dry.
- Apply full coat of Super Grip Premium Problem-Solving Primer or Ulttima Concrete and Drywall Primer.
- Top coat with suitable, good quality finish. Recommend water-based acrylic paint, Ulttima Plus Emulsion.
- Lightly sand area or entire surface if gloss paint was used. Allow to dry.
- Apply a full coat of Troweltex Aqua Overglaze over entire wall corner-to-corner, to seal flashed areas and provide an even surface.
- Reapply top coat.
