When laying a new teak deck, COELAN boat coating should be applied immediately in order to preserve it. The coat also ensures that the teak deck lasts long. COELAN can also be used to renew and restore older teak decks.
Before applying the coat, clean the deck's surface by removing the old paint or vanish. This is by moving a brush that is soft across the grain. After that, gently sand the deck with sandpaper that has #80 as the grain size to get the best surface preparation. Remove the sanding dust with a vacuum cleaning machine to leave the surface clean. Avoid using solvents.
Renovating the deck is essential before any COLEAN Boat Coating is applied. The repair should be on joints that are torn and planks that are severely cracked and damaged by water. Remove all the deck fittings near the working area before you start any work or sanding of the deck.
Measuring moisture content in the wood is also vital. This will help to know if water has gone through sub - deck, the middle of deck planking, and the support beams. You should measure the water content by use of moisture meter. If that is not available, then check the moisture by drilling a hole measuring 8 mm – to - 12 mm or 5/16 inches to ½ inch in diameter in the centre part of the plank of the deck. Roll a small paper towel and put it inside the hole. In case it becomes wet, then there is moisture in the wood. The basis of the leakage should be found and repaired. Make sure the deck wood and the underlying surface is completely dry before applying coating or primer.
Check and repair all deck joints, cracks, and deck planks that are adjacent and loose or broken bungs. Remove the compound used for joint sealing that is loose and clean bonding surface by a sharp item such as a scraper, knife, or chisel. Vacuum the loose material and reseal the joints. Do not reseal using sealant that is silicone based.
Apply several coats of COELAN Boat primer on the wooden surface until the pores on the wood are sealed. Apply two coats to planks and a number of coats to the end part of wood while observing the drying times. Fill the small cracks with polyurethane (PUR) based joint compound.
Apply 5-6 layers of COELAN Boat Coating to horizontal surfaces. Vertical surfaces should get 8 – 10 coats of COELAN Boat Coating, which has been thinned with COELAN Thinner.
Apply the coats evenly with brushes or rollers that have been well prepared.
