DESCRIPTION:
Exfoliation of a of dry paint film in at least one layer as a result of aging which ultimately will lead to complete removal of the paint. In early phases the problem appears as hairline cracks.
CAUSES:
- Application of the paint under wind conditions, cold time
- Over thinning, over leveling of paint
- Inappropriate surface preparation or application of paint on bare wood without pre-priming
- Excessive hardening and brittleness of the alkyd paint as the painted layers successively aged
SOLUTION:
The environmental conditions noted on the product label/ technical data sheet must be observed. Thinning of the product is according to the instructions on the product label. Over thinning affects the product's properties and its resistance over time. Inappropriate surface preparation and application of the product may also influence exfoliation. The solution to be adopted is the removal of paint layers that detach using a spatula or a wire brush. If multi-layer exfoliation occurs, remove the coat to the paint support.
For wood surfaces use prior to re-painting LAZUR wood protection primer 2in1 which penetrates deep into the wood, thus ensuring good adhesion to both the substrate and the finishing layers.
