Surface Preparation
Kop-R-Lastic should only be applied to surfaces that are free from oil, grease, wax, dust, corrosion, moisture, or any material that may interfere with obtaining optimum adhesion.

Concrete and Masonry
Fresh concrete should be fully cured and dried. This may require as much as 3 or 4 weeks. If surfaces are dusty, they should be blown or brushed free and cleaned. Mold release agents or curing agents should be removed as they will prevent good adhesion. If the surface has been exposed to oil based caulking, remove all material and sandblast or cut surface back to remove area of oil penetration. No primer necessary.

Aluminum and other non-ferrous
Unless little movement will be encountered, remove any protective lacquer film with clean lacquer thinner. If the surface has previously been sealed or exposed to the air for a period, remove all previous compounds or surface oxidation via chemical treatment, solvent, or by sandblasting, wire brushing etc. No primer is necessary.

Steel
Remove all corrosion or coatings either by chemical treatment, solvent or by sandblasting, wire brushing etc. If chemical treatments are necessary, rinse thoroughly. No primer necessary.

Glass / Fiberglass
Wipe, if necessary, the surfaces to be sealed with clean, oil-free solvent and dry thoroughly. No primer necessary.

Wood
Remove all paint, other loose coatings. Sand to provide a good, clean surface. No primer necessary, not even on oily wood such as teak.

Joint Dimensions
KOP-R-LASTIC can be used in openings 0.32cm x 0.32 cm (1/8”x 1/8”) to approximately 1.27 cm x 1.27 cm (1/2” x 1/2”).

Back-Up Material
For good installation, when openings are greater than the desired depth, they should be packed with a supplementary material. For these purpose, backer rod joint filler is available and can be used.

Application Guide

1. For neatness of joint, adjacent surfaces should be masked with tape.
2. Apply KOP-R-LASTIC in the joint from the bottom up, filling completely and avoiding any entrapped air.
3. Tool the surface for appearance and insure adequate adhesion between the KOP-R-LASTIC and the joint sides. It is best to tool the surface with Toluol or Xylol.
4. As soon as application and tooling are completed, remove masking tape.

Clean Up
Complete before KOP-R-LASTIC cures with Toluol or Xylol.
