Recommendations and advice for use of film-forming finishes.
The following recommendations (in the tabs below) are provided as a guide only to those finishing systems suitable for the specified applications.
Water based enamel paints (so called because they replace alkyd enamel) that provide tougher more durable paint films are now available.
These acrylic paints are harder films that don’t stick together making them ideally suited for application on window joinery, doors and frames that touch when closed.
Prepare and prime as in previous tabs, use the recommended primer/undercoat of the selected paint brand, but if in doubt chose acrylic primer/undercoat.
If the joinery has been despatched with one coat pre-primed, follow instructions as in "Exterior Mouldings" tab.
Apply two coats of Water Based Enamel at a coverage rate of 12-14sqm/litre.
Once again from two coats not thinned you should expect a dry film of 50-60 microns from a paint at volume solids greater than 35%.
Don’t brush out too far as this will lower the effective dry film required for good exterior durability.
