Seamless Adhesive is a specially formulated, two-part 10:1 ratio universal solid surface seam adhesive. It offers excellent adhesion to a variety of solid surface sheet materials including cast acrylic, cast and densified polyester. Seamless is equally adept as a high-quality adhesive for other dissimilar materials such as natural stone, engineered stone, and wood-based products. The adhesive exhibits excellent performance in resisting water, impact, wear, scuff, boiling water, and high temperatures.
Either Seamless formulation offers excellent adhesion to a variety of solid surface sheet materials including cast acrylic, cast and densified polyester, as well as compatibility with many other materials including engineered stone, natural stone and wood products. Note: For materials other than solid surface, we recommend testing on a material sample before use to verify compatibility.

Accurately match the right Seamless color to your brand of solid surface material!
Seamless adhesives are subject to stringent laboratory color matching with all major solid surface manufacturers' materials. To accurately determine the right Seamless color for your particular solid surface material, refer to the color matching guides for each manufacturer listed below:
Note: Colors shown on a website do not always accurately represent the true color of a material. Use of these color compatibility guides is your best assurance that the Seamless color you select will be right for your material. Do NOT attempt to visually match a color shown on our website with your material Websites use limited color ranges and cannot ensure color match visually.
Seamless™ Accessories
Gruber Seamless™ Adhesives may be applied manually or with automated equipment. Automated application may be accomplished with a variety of 10:1 meter mix dispensers delivering both components to a static mixer. Pre-measured cartridges are also available, as well as the hand-held guns with which to dispense the adhesive. To assure maximum bond strength, surfaces must be mated within the specified working time. Use sufficient material to ensure the joint is completely filled when parts are mated and clamped. All adhesive application, part positioning, and fixturing should occur before the working time of the mix has expired. After indicated working time, parts must remain undisturbed until the fixture time is reached.
