DRYWOOD COATINGS B.V. Drywood Coatings Eliminate WOOD JOINERY’S MOST COMMON FAILURE The wood window joint No Water ---- No problem

DRYWOOD COATINGS B.V. A Breakthrough Drywood Coatings announces the launch of a much welcomed tool to Joinery Manufacturers. Following continued International study on wood joinery failures Drywood Coatings have made a breakthrough on the protection of the Wood Joinery weak link ----- The Leaking Joint

DRYWOOD COATINGS B.V. Drywood Opti-Joint XP • Drywood addresses the weakest link, the joint • Specifically developed to keep Wood Joinery joints protected from moisture ingress. • Beside its gluing properties, Opti-Joint XP protects end grains and joint-lines from water uptake. • 100 % product (no water or organic solvent) • No dangerous / toxic substances (safe for worker and environment)

DRYWOOD COATINGS B.V. Main Advantages of Opti-Joint XP: • Stays flexible to absorb movements in the joint • Fills gaps up to 2 mm • Suitable for common (tropical) hard- and softwoods plus chemically or thermally modified wood. • Product fills capillaries without foaming • No long pressing times or high pressure required. • Overpaintable with common waterborne coatings

DRYWOOD COATINGS B.V. DECIDE BY VISUAL INSPECTION :- An open fitting requires the application of Opti-Joint XP. In case of a very wide fitting: apply Opti-Joint XP on both sides.

DRYWOOD COATINGS B.V. Application Options : - Opti-Joint XP by gun

DRYWOOD COATINGS B.V. Application to dowel-holes : - Take care when fitting the dowel.

DRYWOOD COATINGS B.V. Application of Opti-Joint XP by spray-gun.

DRYWOOD COATINGS B.V. Application of Opti-Joint XP with a roller-spatula which feeds from a pressure-vessel.

DRYWOOD COATINGS B.V. Application of Opti-Joint XP : - The manual way ,cover all surfaces.

DRYWOOD COATINGS B.V. Opti-Joint XP : - On profiled surfaces and in dowel-holes. Apply Opti-joint XP in dowel-holes of the rail.Followed by assembly of the window frame .

DRYWOOD COATINGS B.V. Assemble the parts with low pressure and short assembly times until Opti-joint XP flows out of joint. Do not increase pressure if no material flows out but apply more Opti-joint XP. Fix the joint of larger elements with a nail or screw.
