Wood closed primer formula solves the outstanding problem of wood grain

Wood bulges and deforms or wood grain protuberant,It is a common problem in wood painting. We discussed the causes and solutions of this problem in this year's topic.In the article on wood grain protrusions - water-based paints, we recommend three technical solutions:

1. Use a saturated coating of 3-4% binder solids.

2. Use a quick-drying coating such as sinograce's SPECIAL RESIN POLYMER PF-136 waterborne acrylic primer primer transparent primer formulation

3. Use a hybrid system, water-based coating and solvent-based coating.

After the article was published, some readers wanted to know the formulation of solvent-based coatings for water-based paints. Special offers are as follows:
