Pure Acrylic Caulking (Paintable) - Flexseal GA777

Joint Surface Preparation:

• Ensure that the surfaces you're caulking are clean, dry, and free from any dust, grease, oils, or other contaminants.

Joint Backing:

In cases where needed, you should use an appropriate joint backing rod, like closed cell polyethylene foam. This helps achieve the correct joint depth for your caulking.

Application:

Flexseal GA777 comes in cartridges and can be applied using a skeleton gun. Here's how:

• Cut off the top of the cartridge.
• Cut the nozzle to the desired size.
• Attach the nozzle to the cartridge.
• Firmly extrude the sealant against the surfaces you're caulking to ensure it makes full contact.
• Tool the sealant into the joint by pressing and smoothing it. Do this within 10 minutes after applying the sealant. This helps compact it and achieve a good surface finish.

Helpful Tip:

• For clean and uniform joint sides, it's a good idea to use masking tape on each side of the joint before caulking. Once you've finished tooling the sealant, remove the masking tape immediately.

Now, you're ready to apply your acrylic caulking to seal joints effectively.
