We do not recommend using universal thinners. The use of a thinner with an unknown composition may result in loss of adhesion, lack of proper flow of paint and varnish defects.

Do not add more hardener, because after the base has cured, the remaining hardener will react with subsequent layers, which will be applied to the surface and cause defects. For the product to work properly, please follow the proportions given by the manufacturer.

Yes, you can mix Sea-Line polyurethane paints. The only difference are the pigments of polyurethane paints that determine the color of the paint. But remember to keep the right proportions of base, hardener and thinner.
