Very suitable as a preliminary treatment under waxed, varnished or oiled finishes. For oiled finish see Bio Natural Wood Oil or Bio Teak Oil.
Do not apply coatings to unseasoned or wet timber. Wood should be well sanded, dry and cleaned of greasy, waxy and dirty contaminants using BIO Thinner.
Round off sharp edges. It is also good practice to prime back surfaces. Hardwoods and timbers rich in natural oils, waxes, acids and terpenes should be degreased using Bio Thinner because these substances may mix with the varnish and prolong its drying time.
Let dry for 24 hours. Imperfect coats may require complete stripping before applying BIO Products.
Brush thinly and evenly, working varnish well into the grain. Do not apply more oil than the surface can absorb. Maintain a wet edge when painting.
Remove excess oil with a dry lint free cloth after approx. 15-30 minutes. Test the absorbency of the surface before application: for very absorbent timber, work in small areas otherwise the oil might dry before you are able to wipe off the excess, causing an uneven patchy finish.
Low temperature and humid conditions prolong the drying time. Do not paint below 10C and/or above 80% humidity, in cold damp conditions, when condensation, rain, dew or frost are likely to occur, or hot days, in direct sunlight and on hot surfaces.
Provide adequate ventilation during application and drying. Maximum durability is reached after 21 days.
