High-Performance Elastomeric Sealant

Sashco Big Stretch is a water-based acrylic elastomeric caulk designed to seal doors, windows, siding and mortar joints. It spans gaps up to 2 In. wide and adheres to most interior or exterior surfaces. The 10.5 Oz. cartridge delivers 26 LFT per 1/4 In. bead for efficient coverage.

Suitable For Flexible Sealing Tasks

This sealant suits projects requiring permanent flexibility and moisture resistance across a service range of -30 F to 250 F. It is paintable and stainable after 4 Hrs. Builders needing a heat-resistant formula or a smaller gap-filling capacity should look at alternative products.

Sustained Performance Under Load

The formulation remains permanently flexible through seasonal movement without cracking. It resists mold and mildew growth over a lifetime of exposure. Tools clean with water while the product is wet, and the seal maintains adhesion through repeated expansion and contraction cycles.

Questions about this item

What type of caulking gun do I need for the 10.5 oz cartridge?

A standard 10.5 oz caulking gun fits this cartridge; no special gun is required.

Can I apply Big Stretch over old silicone caulk that I plan to leave in place?

No, silicone prevents adhesion; remove old silicone completely before applying this water-based elastomeric sealant.

How do I confirm the sealant has cured properly after the 4 to 5 day period?

The bead stays permanently flexible, resists moisture and mold, and can be painted or stained without cracking.
