Application

Before application, you will need to ensure that the substrate is dry, firm, and free of all 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. Please contact the Promain Technical Team for further guidance.

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 completely removed. The recommended application thickness is a maximum 2mm.
