MISTAKES EASILY AVOIDABLE

Speckled appearance of transparent stain

Finish applied on moist or frozen wood, or during wet weather.

Wipe clean and let dry thoroughly - refinish with same stain, or if extremely spotted, apply opaque SAICOS HOUSE&GARDEN- COLOUR or SAICOS BEL AIR.

Water marks on finished surface

Wood surface not properly saturated, or calcium residues.

Re-finish surface, pre-sand if necessary, if applied thoroughly and evenly, water marks are not possible with SAICOS finishes, wipe off chalk marks.

Reduced durability

Old varnish not properly removed, wood with specific ingredients (like Canadian Red Cedar), not suffifiently weathered before applying finish, other causes s. “A“ above.

Examine wood condition, protect finish with additional coat of SAICOS CLEAR OIL FINISH, hardwoods rich in substances must be weathered 3 weeks before treatment.

Less coverage

Raw, unprocessed or stratiated wood surface (consumption approx. 30 % higher), wood surface unusually absorbing (f. i. extremely dry soft wood).

Raw, much absorbing wood pre-treat with SAICOS CLEAR OIL FINISH - equalizes absorbing ability, (note: higher absorbance prolongs durability of finish and is not negative).

Delayed drying

Finish applied too thickly, bad ventilation after application, moisture content of wood too high (max. 20 %).

Wipe off surplus material, ensure good ventilation.

“Wrong“ colour shade

Natural colour of wood surface not taken into account. Transparent colour shades are influenced by wood colour).

Applied too thickly.

Stain insuffiently stirred.

Try colour shade out before application. Light transparent colours only apply on light wood (for light colours on dark wood choose light opaque shade of SAICOS HOUSE & GARDEN-COLOUR), or apply one more coat of transparent light shade. Stir well before application.

Odour

Normal: light scent of natural vegetable oils and waxes until finish is dried.

Not detrimental to health, ensure good ventilation after drying, all SAICOS wood finishes are odourless when dried.

Flaking / Peeling

Previous varnish finish not thoroughly removed (therefore no penetration of new finish). Applied on wet or frozen wood. Fungal growth on the wood. Insufficient constructive wood protection (lacking back airing).

Sand down wet wood surface, let dry. Apply SAICOS WOOD IMPREGNATION against fungal attacks. Re-finish, consider constructive wood protection (back airing) when installing the wood.

Discoloration of finish (green/brownish)

Attack of green or brown algae, moss.

Clean wood surface with SAICOS GREEN-EX (self-acting, does not impair colour - biologically degradable, solvent- free, formaldehyde-free). Apply new coat when completely dry, if necessary.

Washing out

Painted on wet wood or finish not dried before rain. Ingredient-rich wood (Canad. Western Red Cedar) should be weathered 2 - 3 months before treatment, applies also to pressure impregnated wood.

Clean spotted surface and re-treat. Remove resin stains with SAICOS BRUSH CLEANER. Re-treat if necessary.

Adhesion problems on exotic hardwoods

Hardwood floors not pre-treated with the extra penetrating COLOR WAX EXTRA THIN (s. directions of use).

Sand down (if necessary, remove finish with SAICOS MAGIC CLEANSER). - When dry and clean, pre-treat with SAICOS COLOR WAX EXTRA THIN, finish with SAICOS HARDWAX-OIL Classic or Premium (quick drying).
