Answer This Question
A: Thank you for the question. OSI QUAD MAX Sealant is not recommended for the application described. This product is not designed for use in traffic-bearing applications, such as on walkways. This is not to say you cannot try, but understand that there are no guarantees the application will provide any type of permanency.

Q:Will a new application of this caulk bond with an existing cured bead of the same caulk?

Answer This Question
A: Thank you for the question. The answer is yes, OSI QUAD MAX Sealant can be reapplied over itself, assuming the original application is not old and the surface is clean. When replacing old or damaged sealant, we always recommend removing any existing sealant before application of new sealant.
by|Aug 28, 2023
A: Yes it will.
Perfect solution would be to remove the old bead and recaulk that way it is better.

A: Thank you for the question. OSI QUAD MAX is designed for use in the home construction industry. It has not been tested for automotive or vehicular applications, so it is not possible to know what kind of results you could expect. You're welcome to try, but keep in mind this intended use is not guaranteed.

Tough Stuff
Builder used it on our house to chalk the concrete siding - I used it same way on the matching She-Shed. Really tough stuff - would have no problem using in place of construction adhesive its bond is so strong. Using it now for another shed.

OSI is the only product to use for exterior siding, windows and doors. Excellent grab, no sag, bonds to most clean surfaces and allows for up to 1/4-inch expansion and contraction. Great selection of colors on the shelf for common use and a huge selection of custom colors from OSI. Far superior to other exterior caulking sealers on the market.

Excellent for Energy Efficiency Projects
[This review was collected as part of a promotion.] This product is easy to use, strongly bonds to all types of siding and windows products! After using OSI Quad Max, I will not use any other caulking products. I used this product on a siding installation during cold, wet weather and had such great results. I was very pleased with the smooth finish.

Great wet application
[This review was collected as part of a promotion.] I needed a product that I could apply in the rain. Quad Max worked great. We sealed a leak along a masonary wall where it met a metal window frame in a light rain. The window was leaking and it stopped. Thanks OSI

Very easy to use, it applied smoothly and consistent. I have a sunroom that had windows covering two sides of the room. They were old single pane, wooden and leaked. I replaced them with 1 picture window on each wall. I closed the areas on either side of the windows and covered it with siding. The White No.001 QUAD Advanced Formula Window Door and Siding Sealant VOC was used to seal the J-channel to the existing structure. It met all my expectations.
