APPLICATION INSTRUCTIONS
- SURFACE PREPARATION
Substrate surface should be thoroughly cleaned with a suitable solvent such as
alcohol, xylene, or methyl ethyle ketone (MEK). Do not use soap, detergent or water.
Wipe the surface dry. Sealant will not properly adhere to a wet substrate.
- MASKING
To obtain a neat sealant line, use masking tape to cover areas adjacent to any joints
before priming.
- PRIMER
A preliminary adhesion test of sealant on the substrate is recommended to ascertain
proper adhesion. For difficult-to-bond substrates, use of a primer (TOSPRIME C,D or
E) is suggested. Please refer to the chart on page 3 for proper primer selection. Allow
primer to dry thoroughly before proceeding.
- BACK-UP MATERIAL
Do not apply sealant in direct contact with organic rubber such as chloroprene or EPT
etc. Rubber closed to into back-up materials may stain the silicone sealant.
- APPLYING AND TOOLING SEALANT
Cut nozzle to desired bead size, break the membrane film completely and extrude
sealant in the joint. Tool immediately, within 5 minutes of application, with a spatula to
spread the sealant against the back-up material and joint surfaces. Remove masking
tape immediately after tooling. Sealant will begin to skin on the exposed surface in
about 10 minutes and cure will progress inward.
