Know Plywood Grades
- Fully waterproof bond (glue) between the layers and designed for applications subject to permanent exposure to weather and moisture.
- Exposure 1. Fully waterproof bond but not for permanent exposure to weather or moisture.
- Exposure 2. Interior type with an intermediate bond. Intended for protected construction applications where slight moisture exposure can be expected.
- Interior applications only.
- Smooth, paintable surface. Repairs to the veneer like replacing knots with patches can be made, but no more than 18. This is the best plywood for cabinets.
- Solid surface. Minor splitting permitted.
- Tight knots and knotholes allowed. Can also have discoloration and sanding defects on the surface as long as it doesn’t impair strength.
- Larger knots and knotholes permitted.
