Frequently Asked Questions

Concrete should not be wet to touch; a quick method to test substrate for surface dampness is to apply tape (duct or masking preferred). If the tape adheres to the substrate, the surface is dry enough to apply sealant. If there is no adhesion between the tape and the substrate, repeat the test in 30-minute increments. The concrete can be damp during application, but do not apply sealant where there is standing water in or close to the joints. Please note that a clean and sound substrate is always required when applying any sealant.

Dymonic 100 can be applied to green concrete 24 hours after the forms have been removed. All concrete sealers or curing agents need to be removed by grinding before applying sealant.

Increments of 20 cases. Lead time, upcharge and minimum order quantities on special colors are listed on current customer policy documents.

Dymonic 100 has been tested and confirmed by ATI to have +100% extension and -50% compressions per a modified ASTM C719 test.

All standard colors in cartridges will be available for sampling.

Curing of polyurethane sealants occurs at approximately 1/16” (1.66mm) depth per day at 75 °F (24 °C) and 50% RH. The cure time will increase as the temperature and/or humidity decreases. A good rule of thumb is an additional 24 hours of cure for every 10 °F (-12 °C) decrease in temperature.

The shelf life for Tremco polyurethanes is 6 to 24 months depending on type of sealant and/or packaging. Please contact Technical Service for specific shelf life of a product at 866-209-2404.
