To safeguard plywood in a concrete setting, a watertight seal is paramount, precluding unwanted consequences like swelling, delamination, or uneven wear. This objective can be attained by initially filling holes with exterior wood putty, subsequently applying Elmer’s Tite Bond II wood glue and Kilz primer, thereby establishing a resilient base for the seal. For added protection, consider coating the surface with waterproofing epoxy, varnish, or oil.
In doing so, while caulking may yield satisfactory results, applying glue via brush strokes can prove more efficient, rendering a neater finish.
