CRL Off-White Wood Sash Putty 1 Gallon — Paintable Window Glazing

• High-quality formulation for face glazing of wood sash
• Goes on smooth and evenly

CRL Wood Sash Putty (SKU: 500GL) is an off-white glazing putty formulated for face glazing and re-glazing of wood windows and sash. It applies smoothly and evenly, blending with most unfinished wood surfaces for a clean, professional finish. Ideal for traditional wood window repair and restoration projects.

Surfaces should be clean, dry, and frost-free. For best results, prime wood first with an oil-based primer. When re-glazing, remove all old putty and bedding. If necessary, warm and soften the putty by rolling it into coils before application. Shape glazing to an angle that sheds water. 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 reached a firm set; use a high-quality oil-based paint for best durability. Packaged in factory-sealed plastic containers to preserve freshness and shelf life. Available in five retail-ready sizes.
