Drywood Opti-Joint XP
DRYWOOD COATINGS B.V.
- 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)
SLIDE 5
Main Advantages of Opti-Joint XP:
DRYWOOD COATINGS B.V.
- 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

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.
