Poor gloss retention

Deterioration of the paint film, resulting in excessive or rapid loss of lustre of the topcoat.

Dirt Pickup

Accumulation of dirt, dust particles and/or other debris on the paint film; may resemble mildew.

Fading & poor colour retention

Premature and/or excessive lightening of the paint color, which often occurs on surfaces with a sunny exposure.

Blistering

Bubbles resulting from localised loss of adhesion and lifting of the paint film from the underlying surface.

Tannin staining

Brownish or tan discoloration on the paint surface due to migration of tannins from the substrate through the paint film.

Poor alkali resistance

Colour loss and overall deterioration of paint film on fresh masonry.

Surfactant leaching

Concentration of water-soluble ingredients on water-based paint, creating a blotchy, sometimes glossy appearance, often with a tan or brownish cast.

Peeling

Loss of paint due to poor adhesion. Where there is a primer and top coat, or multiple coats of paint, peeling may involve some or all coats.

Lapping

Appearance of a denser colour or higher gloss where wet and dry layers overlap during paint application.

Chalking

Formation of fine powder on the surface of the paint film during weathering, which can cause colour fading.

Wrinkling

A rough, crinkled paint surface occurring when paint forms a 'skin'.

Nail Head Rusting

Reddish-brown stains on the paint surface.

Mould

Black, gray or brown areas on the painted surface.

Efflorescence & mottling

Crusty, white salt deposits, leached from mortar or masonry as water passes through it.

Cracking/flaking

The splitting of a dry paint film through at least one coat, which will lead to complete failure of the paint.

Alligatoring

Patterned cracking in the surface of the paint film resembling the regular scales of an alligator
