SURFACE PREPARATION
Ensure that all surfaces are clean, dry, sound and grease-free.
Note: When using a solvent, always provide adequate ventilation. Avoid heat, sparks and open flames. It is recommended that Geocel 480 is not applied to surfaces that are below 5°C.
MASKING
Areas adjacent to the joints should be masked with tape to prevent contamination of substrates and to ensure a neat sealant line. Furthermore, masking tape should be removed immediately after tooling.
PRIMING
A primer is not essential on most common construction substrates.
BACK-UP MATERIAL
Closed-cell polyethene backer rod is recommended where a back-up material is required. Backer rod is available from Geocel.
FINISHING
The joint should be ‘tooled’ within five minutes of application to ensure proper contacts between the sealant and the substrate.
CLEANING
Use a dampened cloth to remove uncured material. However, cured material can be carefully removed by abrasion or other mechanical means.
LIMITATIONS
Geocel 480 is not recommended for external applications.
