(also referred to as Flaking of Paint/ Delamination)

Avoid this by: Ensuring that the surface is clean, dry and free from contamination and has been suitably prepared according to the paint specification. Oily woods, such as teak and iroko, should be degreased with a solvent prior to varnishing. Be sure to follow the overcoating intervals between coats of paint.

Avoid this by: The correct preparation of the surface. Always clean before sanding and remove sanding residue from the surface before applying the next coat of paint. Ensure that the surface is not contaminated during the curing phase.

Avoid this by: Ensuring that correct overcoating interval is followed to avoid solvent entrapment and other contamination. In immersed conditions the blistering could be osmosis.

Avoid this by: Ensuring that the painted surface has not been exposed to moisture or condensation during the latter stages of drying and that the solvent blend is correct. This phenomenon is often seen with amine cured epoxies.

Avoid this by: Thinning your paint to the correct viscosity and ensuring that it is adequately mixed before applying. For two-part paints use the mixed product within the pot life stated on the product datasheet.

Avoid this by: Ensuring that you have applied the correct amount of antifouling, as indicated on the product datasheet. Ensure that the antifouling strength of the product used is suitable for the waters in which the boat is moored and navigates.

Avoid this by: Ensuring that the end grain of your timber is sealed to avoid water penetration under the varnish layer. This will cause the underlying wood to darken.

Avoid this by: Thoroughly cleaning the surface and ensuring that is clear of wax, grease and perspiration (from your hands) prior to the application of the first coat of paint.
