APPLICATION
• Thoroughly clean the rebate by removing any dust, grease, or loose debris. Ensure that the timber is dry by wiping off any moisture with a clean paper towel or absorbent material.
• Inspect the primer’s condition on the frame, paying close attention to the rebate. If any section is inadequately primed or significantly weathered, reapply primer before proceeding with glazing. Applying a single coat of BS5358:1986-compliant primer on new softwood will enable adequate oil absorption into the frame.
• Begin by applying putty to the rebate and placing setting blocks.
• Position the pane on the setting blocks, ensuring it is centered, and press it into the putty to achieve a back bedding of 1 – 2mm consistently. Secure the pane mechanically using metal sprigs or clips.
• Use location blocks, especially in side-hung opening windows, to hold the glass securely in its place.
• Apply additional fronting putty, using a knife at an angle and finishing approximately 2 mm below the sightline. Seal the putty to the glass by brushing it gently with a soft brush. Knife off the back bedding, sloping it away from the glass.
• Maintain the correct fillet size for optimal setting: a maximum of 15mm in height and 25mm in width, and a minimum of 8mm in height and 10mm in width.
LIMITATION
• Avoid direct usage on laminated glass; reach out to our Technical Department for guidance.
• Refrain from using paints containing potent solvents like xylene.
• Contact our Technical Department before using on insulated glass units.
• Incompatible when the frame/product will undergo staining or coating with a microporous paint (refer to Colourglaze putty).
• Not intended for bead glazing of single glass; consult the Butyl 66 data sheet.
• Verify compatibility of all components within the glazing system.
