Insl-X Max Block Primer

Insl-X® Max Block™ is the next generation of water-based primers, formulated to provide advanced stain blocking properties when compared with other typical water-based primers. Years of testing on multiple substrates in both interior and exterior environments have resulted in a product with proven effectiveness across multiple types of stains and tannin bleeding type woods such as redwood and cedar—providing a lower-VOC option in lieu of an alkyd-based stain blocking primer.
