High-performance elastomeric sealant

Sashco Big Stretch 10016 is a professional-grade caulk designed to move with a building as it expands and contracts. The 10.5oz cartridge delivers extreme elasticity that prevents cracking over time, creating a permanent weatherproof seal on windows, doors and siding. Superior adhesion works on a variety of surfaces and the formula remains freeze-thaw stable through 10 cycles.

Suitable for interior and exterior gaps

This sealant suits homeowners and tradespeople who need a paintable, water-clean-up caulk that sticks to itself and handles structural movement. The unique stop-flow plunger pulls product back into the cartridge to eliminate waste during application. Buyers who need a rigid, non-flexible filler or a product for constant water immersion should look at a different type of sealant.

10.5oz cartridge with stop-flow plunger

The 10.5oz size and integrated stop-flow plunger are the key specifications that determine whether this pack fits the project scope and preferred application method. Each pack contains six cartridges, providing enough material for multiple joints or a whole-house job. No other capacity or dispensing mechanism is available for this model.

Questions about this item

How do I load the 10.5oz cartridge and avoid the common mistake of not releasing the stop-flow plunger?

Cut the tip, puncture the inner seal, place the cartridge in a caulking gun, and pull the trigger once to disengage the unique stop-flow plunger so the sealant flows instead of retracting.

Will I need to replace the 10.5oz tubes if they freeze on the job site during winter?

No, the sealant is freeze-thaw stable through 10 cycles, so tubes that have frozen can still be used after thawing without replacement.

At what point will the sealant stop stretching and crack under repeated seasonal movement?

The extreme elasticity is designed to move with the home and won't crack over time, creating a permanent weatherproof seal that lasts the life of the joint.
