Tremco 830
Tremco 830 is a one-part, thermoplastic elastomer that provides high-performance, flexible seal in glazing and siding applications.
Tremco 830 is a thermoplastic sealant from Tremco. Tremco lists it for glazing (face bedding, cap beads, miter joints), siding, window. Tremco recommends a surface temperature of at least 40 °F (5 °C); colder application requires its cold-weather guidance. Cranco carries it, and which counter has it on the day changes, so ask at the counter.
Tremco 830 is a one-part thermoplastic elastomer for glazing and siding. In glazing it goes on face bedding, cap beads and mitre joints in window profiles; in siding it goes on sill trim, flashings, fascia, J-trim, F-channel and crown moulding, and around the perimeters of wood, PVC and aluminium residential windows and doors.
Tremco makes it in 20 colours matched to popular siding and window tints, and it takes latex paint. Cranco carries Tremco at Concord, Barrie and Mississauga. Call the branch to confirm the colour and size in stock, and the price.

Can you paint Tremco 830?
Yes. Tremco specifies latex paint but does not publish a paint-ready interval, and its skin and tack-free figures conflict. Confirm the waiting time with Tremco before scheduling painting.

How fast does Tremco 830 set?
Tremco’s linked data sheet disagrees on skin and tack-free times. Its table lists 30 minutes for skin formation and 5–10 minutes tack-free; its cure paragraph gives 5–10 minutes for skin formation and 30 minutes tack-free. Ask Tremco to resolve the timing before scheduling work that depends on either stage. The sheet also states that colder temperatures lengthen drying time.
What colours and sizes does Tremco 830 come in?
Twenty, shown on the colour chart below: clear, polar white, arctic white, ivory, linen, gray stone, slate gray, pearl gray, clay, sandalwood, translucent, white, buff, prestige beige, colonial red, forest green, timbertone, chocolate brown, dark brown and black. Tremco matches them to popular siding and window tints. It comes in 300 mL cartridges and 600 mL sausages.
How cold can you apply Tremco 830?
Tremco recommends surface temperatures of 40 °F, 5 °C, or above at the time the sealant goes on. Its cure baseline is 72 °F, and it adds one day of dry time for every 20 °F below that, so a 52 °F morning already costs a day.
Where should you not use Tremco 830?
Tremco keeps it off damp or contaminated surfaces, and away from contact with polystyrene, insulated glass seals and laminated glass. No sealant in this catalogue is cleared as an insulated glass sealant; TremGlaze U1600's sheet rules that use out in the same words.
