Technical data sheet

Surface preparation

The substrate must be dry, firm, and free of dust and grease. Using a V-joint filler is no substitution of good joinery praxis with fully gluing of corner joints. Pretreatment is required for wood substrates not meeting Durability Class 3, EN 350:2016. Teknos has a range of preservative products meeting the requirements of EN 599-1, please contact Teknos for further guidance.

Application

The V-joint can be smoothed with water and a suitable tool (e.g., jointing trowel). Remove excess smoothing agent and be sure that excessive water/humidity is complete removed. Recommended application thickness is maximum 2 mm.

Application conditions

Optimum temperature for products and surroundings: +15°C - +40°C Optimum relative air humidity: below 80% Upon ongoing contact to moisture, the joint will get slightly haze. This effect is reversible and disappears once the joint becomes fully dry again. Good ventilation must be provided during application and curing.

Storage

The storage stability is 9 months. Storage temperature +5°C -+35°C at 50% RH.
