Michem Wood Coating

Michem® Wood Coating products are low-VOC and set the water resistance standard for waterborne deck stains and sealants. They can be added to sealants or used alone. Providing great versatility for exterior wood protection, each solution in Michelman’s line of topical wood treatment additives passes the ASTMD-4446 standard for swell resistance.

Setting the Water Resistance Standard for Exterior Wood Protection

Michem® Wood Coating 70LV is the most hydrophobic of Michelman’s solutions, while Michem® Wood Coating 75 offers outstanding re-coatability for improved wet out. Both Michem® Wood Coating 70LV and Michem® Wood Coating 75 reduce water uptake and provide swell resistance to help control cracking and splintering on exterior wood application such as wood decks and fences.
