CRL Wood Sash Putty is formulated for primerless application to wood. It goes on smooth and evenly, and its off-white color blends with most unfinished wood surfaces.

Surfaces should be clean, dry and free of frost. When re-glazing, remove all old putty and bedding; using a 4500, PR9000 or AK40. If necessary, place glazing in hands and roll in to coils to warm and soften. Smooth glazing to an angle that sheets water with a putty knife using a 2BE118, 4701 or 2S114. Typical dry time before painting is four to six weeks depending on temperature and humidity. Putty must be painted after it has skinned over and attained a firm set. For best results, use a high quality oil-based paint.
