APPLICATION AND USE

Preparation PREVIOUSLY VARNISHED WOOD:

In Good Condition: Clean with thinners. Sand smooth with 280-320 grade paper. Remove sanding dust with thinners.

In Poor Condition: Remove all previous coatings.

Apply a minimum of 3-5 coats. Sand every 2-3 coats, using 320-400 grade paper.* Remove sanding dust with a dust wipe.

BARE WOOD: Sand smooth with 80-180 grade paper and then 280 grade paper. Remove sanding dust by brushing, dusting and wiping. If wiping with solvent then allow to dry completely before applying the first coat.

OILY WOODS e.g. Teak: Must be adequately degreased (Brushing Liquid 333 is recommended) and prepared prior to application of Compass. Ensure the surface is completely dry before applying the first coat. Prime, if required, with Clear Wood Sealer.

Brush/Roller: If Clear Wood Sealer has been omitted, thin the first coat 30 percent with Brushing Liquid 333. Subsequent coats can be thinned up to 15 percent dependent upon ambient temperature, application conditions and personal preference. Apply a further 3-5 coats (brush)/ 4-6 coats (roller), until satisfactory finish is achieved. Sand every 2-3 coats, using 320-400 grade paper.* Remove sanding dust with a dust wipe.

* Initial aesthetics may be further improved by sanding between every coat.

Method 

Pour the amount you expect to use in a separate container. Avoid using direct from the can. Strain it through a paint strainer to ensure there is no contamination. Do not apply too thickly.

Hints

Mixing Stir thoroughly before use.
Thinner Brush - Brushing Liquid 333. Spray - Special Thinner 216.
Thinning Thin the first coat by 30 percent using recommended thinner. Subsequent coats can be thinned up to 15 percent dependent upon ambient temperature, application conditions and personal preference to allow best finish.
Cleaner Brushing Liquid 333
Conventional Spray Pressure Pot: 1-2 bar 14.5-29 psi (gun pressure), 8-10 psi (air pressure) Tip Size: 1.2-1.4 mm/ 47-54 thou. Thin 20-25 percent with Special Thinner 216.

Brush

Always use a clean brush that is kept specifically for varnishing. Clean brushes before use.

Roller

If rolling, use a thin nap roller and "tip-off" with a clean natural bristle brush or pad otherwise air bubbles may become trapped in the film.

Other Spray pressures listed are recommendations only. The applicator may use any settings which yield the best results for the individual spraying technique and current weather conditions. Avoid using direct from the can. Pour the amount you expect to use in a separate container. When applying Compass by brush or roller, it may be necessary to adjust the number of coats applied to ensure the total specified system dry film thickness is achieved.

Some Important Points

Never leave bare wood exposed for long periods of time as it will absorb moisture. Do not use straight from can otherwise contents will age prematurely. Failure to follow proper dry times carefully will cause improper drying, wrinkling and loss of adhesion. Avoid painting in direct sunlight. Use above the waterline only. Only use recommended thinners.

If maximum overcoating times are exceeded, sand with 280-320 grade paper.

Product temperature should be minimum 15 degrees C/60 degrees F and maximum 30 degrees C/86 degrees F.
Ambient temperature should be minimum 5 degrees C/41 degrees F and maximum 35 degrees C/95 degrees F.
