When combining wood and resin, such as when making serving boards, tables, or decorating wooden blanks, it is important to prevent air from escaping into the resin from the wood, ideally by sealing its surface.
Penetration prevents bubbles and absorption
However, when applying a primer, our goal is not only to prevent bubbles from penetrating the resin but also to seal the surface so that it does not absorb the resin into the mold, causing the level to drop and requiring us to mix and color more resin. It is very difficult to match the exact shade, which could lead to an unattractive operational seam. An important property of the primer is also to enhance the strength of the bond between the wood and the resin.
Art Epoxy Primer
The ideal tool for priming wood and other natural materials is the special Art Epoxy Primer, available in our offer. Apply the primer always to a clean and dust-free surface, ideally using a brush in a thin layer. If the primer soaks in due to the surface's absorbency and the surface is not well sealed at first glance, you can repeat the application several times. Once fully cured, you can continue working with the prepared wood as usual and combine it with resin.
The advantage of Art Epoxy Primer is that it is a water-based dispersion, meaning it can be diluted with water. This means that by diluting it, you get more coating material for less money. Another option for sealing the surface is to use regular resin. Due to its density, it does not soak in as much, and unlike Art Epoxy Primer, it does not help as much with the bonding of wood and resin.
Primer is essential when working with wood
Do not forget to use a primer, and do not skip it for time reasons. The goal is always to ensure that the final resin product is perfect and ideally free of bubbles; skipping this step could ruin all your efforts.
