Surface Preparation for DYNA-SEAL™ Elastomeric Caulk

Priming is not required on most surfaces, however, if adhesion to a particular substrate is in question, a test patch application is recommended. For best results all surfaces being caulked must be clean and structurally sound. All foreign materials such as dirt, dust, oils, grease, soot, loose paint, etc. should be removed. Do not use Xylol or MEK to clean joints or to remove surface coatings, unless the surface can be allowed to dry before application of the sealant. If the joint is wet with solvent, the sealant will not adhere properly. Contamination from curing agents and form release agents should be avoided.

Applying DYNA-SEAL™ Elastomeric Caulk

Joint Design: For optimum results, joints should be a minimum of 4 times greater than the anticipated movement. Minimum recommended joint size should be 1/4” x 1/4”. Maximum joint size should be 1/2” wide by 3/8” deep. Joint Backing: An open cell backer rod should be used to control joint depth. In shallow joints, a bond breaker tape should be installed to prevent three point contact. Application and Tooling: Apply with conventional equipment, filling the joint completely. When temperatures are below 40 degrees F, application will be easier if sealant is warmed. When temperature of the surface exceeds 140 degrees do not apply until the surface cools. A soap and water solution or a solvent such as Xylol may be used as a lubricant for tooling. Do not let tooling agents contaminate open joints. Painting: DYNA-SEAL™ elastomeric caulk may be painted after 24 hours at temperatures above 50℉. If using a relatively inflexible paint, allow sealant to dry for 3 days before painting. DYNA-SEAL™ elastomeric caulk may be coated with any latex and most oil based paints. Some paints may crack due to dynamic (moving) joints. See paint manufacturer’s specifications. Cleaning: Remove caulk material from tools before it cures by scraping and/or using solvents such as Acrylic Thinner, Xylol or MEK. Cured materials may be removed by cutting with sharp tools. Observe manufacturer’s precautions when using toxic or flammable solvents.

    I use many caulks and silicones. This is the one you keep in the truck for those jobs where you need something that holds onto many surfaces, even damp & cold, is paintable, and can fill in larger gaps. This gets the job done.

    I used it on sealing a crack in the foundation where water was coming in; no more leak. I even told my friends about it. I showed them what I did. I sprayed water where the crack was and no water came in. Amazing! I sealed around my vents and 1 hour later painted. The paint went right over it, no problem; you can’t even see where I sealed. It was easy to work with. It’s an awesome product, and it’s about time. Thanks.

    This product has better adhesiveness than 3 other sealants that I used at the same time in order to compare.

    I used this product to caulk a seam where the roof joins a wall. It worked very well and I especially like the clear color. It has great versatility; you can use it anywhere.

    The compatibility and adhesiveness of this product is unbelievable. It provides one stop shopping for all your caulking and sealing needs. Very reasonably priced and excellent quality. I would recommend this product to all handymen. Worked great on my chimney & roof and no black tar to deal with.

    I fixed a problem leak on my brother’s roof that his roofer hadn’t been able to fix- it was a 90º+ day!

    Being a general contractor I use many products of this type. I used this product in two different applications and it seemed to work well.
