How Do I Paint Accoya?
Assess elevation aspect, take into account direct sunlight, colour choice, drying times.
Colour choice will have a direct effect on the thermal dynamic of the timber, Accoya although durable will still bleed resin and tannin, if a dark colour is applied to an elevation which is exposed to sunlight for long periods the heating of the surface will cause a resin migration which could result in blistering. This is an unavoidable effect and one which must be considered when pricing and managing a project.
- Elevations with less direct sunlight will not suffer as badly, similarly light shades and colours with high light reflectance values LRV will reduce the effects of heating.
- Ensure surface is clean and free from mould, dirt, grease and other forms of contamination.
- Treat nail heads with appropriate primer to avoid rust staining
- KNOTS: knotting compounds will help in the prevention of staining but will not prevent the excretion of resin
Wash/ brush down all surfaces as necessary, remove all mould and biological contamination using appropriate cleaning agent Tikkurila Mould Removal Solution or similar.
Apply one coat of Ultra Primer to all surfaces.
Allow minimum 2 hours before overcoating.
