| Skin time | Application text: 10 to 30 minutes. Property table: 30 minutes. | Application text and property table: 5 minutes. | Application text: 75 °F (23.9 °C), 50% RH. Skin-time tables: ASTM C679, with no temperature or humidity stated on those rows. |
| Tack-free time | 5 to 10 minutes | Less than 1 hour | Clear/translucent table: 73.4 °F (23 °C), 50% RH. Colours table: ASTM C679; no temperature or humidity stated on that row. |
| Surface preparation | Sound, clean and dry surfaces. | Description allows wet/damp surfaces; preparation instructions require sound, clean and dry surfaces. | Each sheet, Product Description and Substrate Prep. Confirm the colours sheet’s conflicting instructions with Tremco before applying to a damp surface. |
| Exclusions | No continuous underwater use, below-grade applications or surface defects. No butt joints under 1/4 inch wide or joints over 1/2 inch wide by 1/2 inch deep. | Same exclusions and joint-size limits. | Both sheets, Limitations. Use foam backer rod when depth exceeds 1/2 inch; recommended bead size is 1/4 to 3/8 inch. |
Skin time and tack-free time describe the surface; neither gives a full-cure time. The clear/translucent table lists tack-free time before its skin time, and the colours sheet gives conflicting damp-surface instructions. These published differences remain unresolved. Ask Tremco to confirm them for the version and job before relying on them.

What is TremPro 830 Plus used for?
Siding trim, flashings, fascia, J-trim, F-channel and crown moulding; wood, PVC and aluminum window and door perimeters; and face bedding, cap beads, mitre joints and mulling in window profiles. For a joint that needs a different movement rating, compare Tremco’s Dymonic 100 using its own sheet.
How fast does TremPro 830 Plus skin over?
The clear/translucent sheet gives 10 to 30 minutes in its application text at 75 °F (23.9 °C), 50% RH, and 30 minutes under ASTM C679 in its property table. The colours sheet gives 5 minutes. See the table above for the separate tack-free values and conditions. Skin time is separate from full cure.
How cold can you apply TremPro 830 Plus?
Tremco puts the application range at 20 °F to 120 °F and says the sealant can be applied down to 20 °F where the general Tremco rule is 40 °F or above. Tremco prints that range in its limitations, which is where you will find it below.
What joint size does TremPro 830 Plus take?
Tremco rules out butt joints under 1/4 inch wide and joints over 1/2 inch wide by 1/2 inch deep, and asks for foam backer rod where the depth passes 1/2 inch. The recommended bead is 1/4 to 3/8 inch, laid convex so the sealant touches both faces. Tremco says a flat or concave bead after cure is normal shrinkage.
Is Tremco 830 the same as TremPro 830 Plus?
No. Tremco 830 is the earlier product in the same family, also a one-part thermoplastic elastomer for glazing and siding. Cranco carries both, and Tremco 830's own page carries its specifications. Call the branch for what it has.
