Acrylic paint base (primer/sealer)

Water-soluble surface treatment agent

Stain-resistant sealer

The tar-stopping sealer is a water-based, transparent primer that is applied to the surface of wood to prevent tar and scum from seeping out. This prevents discoloration of the work caused by tar. The recommended amount to use is about 100ml per 1m2.

Metal and glass primer

This primer is used on materials that do not absorb moisture, such as metal, glass, ceramics, and plastic. Using this primer improves the adhesion of acrylic paints. The recommended amount to use is about 50ml per 1m2.

Primer for absorbent materials

The absorbent primer is suitable for absorbent materials with brittle and powdery surfaces, such as calcium silicate board and plasterboard. By using this primer before painting, it hardens and strengthens the material, reduces the absorption of acrylic paint, and improves adhesion. The recommended amount to use is about 300ml (1 coat) to 500ml (2 coats) per 1m2.
