Overview
Production joint work wants a bigger tube. KST058411 is the 29 oz black cartridge of the Uniflex solvent-based tripolymer, six to the case, and it is the size ordered when black sealant is going down by the hundred feet rather than the detail.
The material matches the 10.3 oz KST058410 exactly, including the substrate list that reaches from coated metal (Kynar) and steel through brick, concrete, glass, vinyl, tile and wood to asphalt, application listed from 0 F to 140 F, service from -40 F to 180 F, tack free at 2 hours and cure at 4 to 6 days. The practical points are the gun, which has to be a barrel gun sized for 29 oz, and the case count: six cartridges rather than 24. White and clear come in the same size as KST058401 and KST058451.
Application
- Prepare the whole run before you start gunning. Clean, dry, sound joints, with old sealant raked out and dust and oil removed.
- Prime by substrate where the system requires it: concrete primer on cured concrete, metal primer on steel, the stated preparation elsewhere.
- Detail work comes before the field coats, so a long finished run is not disturbed by coating operations later.
- Gun and tool in sections. The bead is listed tack free in about two hours, and a big cartridge makes it easy to outrun the tooling.
- Follow the manufacturer’s product data sheet for joint design, bead size, cure and anything that may be applied over the sealant.
Ordering
KST058411 is sold by the 29 oz cartridge and by the case of six. Stocked cases ship in 1 to 3 business days; if the color or size is off the shelf it is ordered in on a 1 to 2 week lead. The product is solvent-based and ships as regulated freight, quoted with the order. Send part numbers, quantities, the site ZIP and your dates through the quote form. Every price is quoted per project.
Where it's used
-
Long asphalt and bituminous joints
Extended termination and lap detailing on asphalt surfaces and bituminous roofs, where asphalt is on the maker's substrate list.
-
Coping and parapet runs
Continuous joints along brick, block and concrete copings on older buildings, where a dark bead suits the weathered surface.
-
Dark metal panel lines
Long laps, ridge and eave trim on bronze, brown and black coated metal (Kynar) and steel roofs.
-
Tile ridge and hip lines
Continuous ridge and hip joints on tile roofs, where the run is long enough that reloading small tubes dominates the labor.
-
Deck and curb joints
Joints across concrete decks and around large curbs, worked into a porous surface in one continuous pass.

Questions
- Is this the same sealant as KST058410?
- Yes, in a bigger tube. Same black solvent-based tripolymer, same substrate list, same 0 F to 140 F application range, same stated cure. The cartridge is 29 oz and the case holds six.
- What gun does it take?
- A barrel gun sized for a 29 oz cartridge. A standard cartridge gun will not accept it, which is the most common surprise when a crew orders the large size for the first time.
- Does the bigger tube change the cure?
- No. Tack free is listed at 2 hours and cure at 4 to 6 days regardless of cartridge size. Bead depth and conditions are what move real cure times, and the data sheet covers that.
- How do I compare price between sizes?
- By total ounces per case. Six 29 oz cartridges is 174 oz; 24 of the 10.3 oz size is about 247 oz. Send both part numbers on the request and the quote prices each.
- How does it ship?
- As regulated freight, since the product is solvent-based, quoted with the order. Stocked cases ship in 1 to 3 business days.
