PG1 Replacing failed glazing sealant (exterior and interior)

PG1.1 Remove cracked/detached sealant from the entire lower surface and a minimum of 300 mm on both vertical sides. Use a utility knife. Remove sealant residue.

PG1.2 Prep work on wooden subsurface

• Check the quality of the wood in and around the rebate as well as the window, door and frame. Remove soft wood by sanding. In the event of other damage, follow the curative procedures.
• Check if the sealant joint meets the required dimensions (4 mm wide, 6 mm deep).
• If necessary, rout out the existing rebate to the required dimensions. Set the sealant cutter according to the operating information and corresponding instruction.
• Measure wood moisture (≤ 18%) with the EASY-Q™ wood conditioner CS1. If the moisture content of the wood is too high, let it dry naturally in the air.
• Sand the rebate and carefully remove dirt and wood residues.

Prep work on metal subsurface

• The contact surfaces for DRY SEAL™ MP must be free of dirt and moisture. Check the metal contact surface for oxidation residues. If this occurs, sand the metal lightly and remove dirt and dust.

PG1.3 Clean the glass surface with a glass cleaner. Remove old sealant residue carefully.

PG1.4 Apply the DRY SEAL™ MP with a small excess in the rebate. Make sure that there is optimal contact with the wood and glass, or metal and glass, and that air inclusion is prevented. finish the sealant fillet with an EASY-Q™ Sealant Applicator or modelling knife in a smooth motion. Ensure that water can easily drain off the seal and not pool or collect.

PG1.5 After curing, remove any sealant residue from the glass surface, using a glass scraper.

If ‘DRY SEAL™ MP seam’ is to be painted:

PG1.6 Prime the DRY SEAL™ MP with water-based primer after a minimum of 2 hours and a maximum of 30 days. If painted after 30 days, lightly sand the top layer of DRY SEAL™ MP.

PG1.7 Treat according to painting advice.
