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 applications such as wood decks and fences.

Michem® Wood Coating 44 helps produce wood coatings with excellent weatherability characteristics. This topical wood treatment imparts outstanding water beading, along with improved water and swell resistance for wood decks, fences, and garden sheds. It penetrates deep into wood substrates and is user-friendly. Its superior water-resistant properties improve surface aesthetics and color integrity. Michem® Wood Coating 44 produces a natural surface appearance and is particularly suitable for softwood as well as extending the look and use of outdoor wood furniture.

Michem® Wood Coating 50 provides excellent water resistance for topical wood coatings. This product works to prevent the swelling of wood in the presence of water as well as providing great water bead, and water repellence in exterior wood applications such as wood deck stains and sealants.
