Whitening

 

Whitening

Causes

  1. Substrate affected by dew, rain or humidity during the drying time. In such conditions,solid colour coatings become flat, and transparent coatings become whitish or greyish.
  2. Prolonged presence of water on water-based varnish.
  3. High humidity during application or drying of clear water-based sealant.

Solutions

  1. Sand affected areas and apply a new coat. If the surface is badly damaged, remove the coating and start over again.
  2. In the case of a minor problem, sand the surface lightly and apply a new coat. If the problem is major, sand the surface and start over again.
  3. Allow the sealant to dry: it should recover its clarity.
  • Let the product dry for 2 to 3 hours before any sign of rain or dew. Comply with the application temperature as well as the humidity rate recommended for this product.
  • Use a solvent-based varnish on tables used for eating.
