– Sealing and glazing of windows, doors and skylights
– Conventional glazing and storefronts
– HVAC, plumbing, roofing
– Sealing trucks, trailers and RVs
– Marine applications
– Appliance assembly
– Glass, tile, fiberglass, plastic, ceramic, wood and painted metals
In all cases, make sure the joint design is correct. Proper joint design minimizes stresses on the sealant. Use masking tape if desired for areas adjacent to the joint to be sealed to prevent surface contamination. Apply sealant to dry, clean surfaces. Do not break cartridge seal until just before use. Surfaces should be dried before the sealant is applied. Tooling and finishing Tool joint, if necessary, and remove masking tape. Tooling should be completed in one continuous stroke. Tool immediately after sealant is applied and before a skin begins to form. Dry tool – do not use soap, water or oil as a tooling aid. Remove masking tape immediately after tooling is completed. Complete tooling within 5 minutes of sealant application.
Uncured Sikasil GP may be removed from tools and equipment with solvents such as isopropyl alcohol or xylene if cleaned before sealant has begun to cure. Strictly follow solvent manufacturer’s instructions for use and warning statements. Once cured, the material can only be removed mechanically. Hands and exposed skin should be washed with soap and water immediately after use. Do not use solvents on skin!
The substrate must be clean, dry, frost free, sound and free of any oils, greases or incompatible sealers, paints or coatings that may interfere with adhesion.
Porous substrates: Clean by mechanical methods to expose a sound surface free of contamination.
For cleaning non-porous substrates, use two cloth cleaning method using xylene, isopropyl alcohol or an approved, clean, pure non-diluted industrial grade solvent. Allow solvent to evaporate completely prior to sealant application. Strictly follow solvent manufacturer’s warnings and instructions for use.
