EPDM Liquid Rubber adheres well to all types of wood.  If the rubber is applied directly to the wood, however, its appearance will not be uniform because of the differing porosities of the surface.  This condition can be avoided by first priming the wood with an oil based primer or Pro Guard's Proflex Primer®.  Some applications where EPDM Liquid Rubber works well on wood are:  Railings, Fence Posts, Planters, and Window Boxes.

Plywood Roof Decking

EPDM Liquid Rubber may be used on plywood roof decking as a moisture barrier to protect the wood but should not be used as the primary waterproofing for the roof.  The many joints and potential for warping make this an impractical use of the product.  Shingles, Metal or Roofing Membranes are appropriate roofing materials.  Do not use EPDM Liquid Rubber direct to plywood on any roof, whether flat or sloped, over a heated living space.  Liquid Rubber may be applied direct to primed plywood (oil based primer) on small utility and garden sheds and garages which are not insulated or heated and the roof has a slope of 30° or more.  The joints between panels must also have a bridging seal such as Butyl Tape
