SURFACE PROBLEMS AND REMEDIES

FLAKING PAINTED SURFACES (CEILING AND WALLS)



Description

Areas of a painted surface that have lifted and come away.

Possible causes

• Lack of surface adhesion
• Lack of surface preparation: a powdery loose surface, which can be old whitening, or size-bound distemper, or paint which has become powdery with age
• Too many old coats of paint causing a heavy build-up on the surface
• Dampness on the surface
• Lack of adhesion between coats of paint.

Remedy

Scrape off as much loose material as possible, wet, scrub and wash area. Sand down the edges of scraped area, apply filler to edges and sand when dry (to help hide edges). Apply a coat of sealer (oil-bound is the most effective, see page 47). Allow sealer to dry thoroughly before applying finishing coats. Alternatively, use a steam stripper to soften loose coating, and scrape off as much as possible, then wet, scrub and rinse the area. When dry, apply sealer coat (as above).

FLAKING TEXTURED PAINT SURFACES (CEILINGS AND WALLS)

Remedy

When this occurs the only real remedy is to remove the texture coating.

Porous granular type finishes Remove by softening the paint with a steam stripper, and scraping off.

Non-porous texture coatings Strip it off using a special propriety texture paint remover (liquid or gel). Great care should be taken to protect the eyes and adequate ventilation to the room must be provided. It is a good idea to wear protective gloves. Always follow the product information. It is usually best to apply the remover to small sections of surface at one time.
