QUAD MAX siding & window sealant is designed for sealing around interior/exterior windows, doors and siding. It bonds to a wide variety of materials without need for a primer, including fiber cement, cedar, brick, stone, coated aluminum, fiberglass, vinyl, PVC, stucco, EIFS, wood, glass, and flashing tapes and Kynar® coatings.

This Quad Max caulk matches James Hardie fiber cement siding prefinished siding colors to take the guesswork out of color matching. It offers long-term durability against the harmful effects of sun exposure, resists bubbling and has no shrinkage. Proven to stick on wet and cold surfaces, it is easy to use in all temperatures and has a fast 24-hour curing time.

Quad Max caulk comes in 9.5 ounce tubes and is sold 12 tubes per case. Where lap meets trim, match caulk to the color of the siding. One tube will cover approximately 20 linear feet with a 3/16 inch gap.

Note: Do not tool or smear/feather on prefinished colored siding and trim, as this will reduce any sealant's ability to withstand UV exposure and joint movement. Do not use as a nail hole filler or in touch-up applications on prefinished exterior building materials. Follow manufacturer’s instructions for nail hole filling. Not recommended for field joint/butt joint applications on pre-finished exterior claddings and trim materials.q
