Preparation

Always ensure the surface to be treated is clean, dry and free from any dust, algae, fungi or moss.

For New Timber:

Resinous deposits should be removed with a scraper.
Degrease the surface with a lint free cloth and suitable solvent, allow to evaporate fully before applying Sikkens.
For previously painted or worn wood use a fine sandpaper of 240 grit work in the direction of to abrade the surface the grain remove any loose paint.
Dust down entire surface.
Fill any cracks, holes or chips, always use a filler designed for timber.

Application

Before applying stir the product thoroughly and test a small area to ensure colour and adhesion. Colours can vary dependant on surface to be treated.

Do not apply when there is the risk of rain or when temperatures are below 8°C or above 25°C.
Protect from frost and rain until dry.
Always ensure product is fully mixed before and during application to ensure consistency in colour and sheen.
Do not thin.
For best results use a good quality, synthetic-fibre brush designed for the application of water borne products.
The product should be applied in a full flowing coat, laying off in the direction of the grain, using the minimum number of brushstrokes necessary to produce an acceptable finish.
Avoid over brushing.
Apply 2-3 coats.
Allow 5 hours between coats.
This initial coat should satisfy the porosity/absorption of the timber. Carefully denib the first coat using a fine grade nylon abrasive pad or a fine grade (P240 or finer) wet or dry silicon carbide abrasive paper, remove all dust.
On new wood were possible the first coat should be applied all round prior to fixing.
Pay special attention to areas of exposed grain e.g tops and bottoms of doors.
