How to use
Prepare the surface so it is clean and free from dust, grease, and loose material.
Cut cartridge tip, attach nozzle, and load into a caulking gun. Cut nozzle to the required bead size.
Apply a continuous bead, pressing firmly so the product contacts both sides of the joint. Tool with a soapy solution before skinning.
For neat edges, mask before applying and remove tape before skin forms.
Clean up
Uncured product cleans off with mineral turps.
Once cured, remove by scraping or sanding. A dedicated silicone and adhesive remover can assist.
