Seaming Adhesive

Seaming Adhesive

Epoxy Modified Methacrylate Adhesive for all surfacing materials

  • Laminating / Seaming / V-Groove systems
  • Automates Adhesive Application
  • Provides the Strength of Epoxy, the Speed and Color stability of Acrylic
  • Reduce Waste, Eliminate Hand Mixing and Tinting
  • Create invisible seams and laminations
  • Polish to match the gloss of surrounding material
  • Color Selector cross-reference charts available for all major brands.
  • Standard formulations develop handling strength in as little as 20 minutes.

This Epoxy Modified Acrylic reduces labor by eliminating hand mixing and is designed to produce strong, fast curing, and invisible seams.

Seaming Stone and Quartz with Altima Adhesive

Seam Preparation

  • Clean seam with Polish Acetone or Alcohol to remove dust from the seam. (Joint must be clean and dry for best results).
  • Apply masking tape on each side of the seam, back about 1/16 inch from the joint. (Build up 2 to 3 layers of tape).


  • Attach mixing tip to cartridge and dispense.
  • (Refer to individual cartridge instructions) Discard the first 5-10 ml to ensure Activator is present in mixture.
  • Apply a bead to the surfaces to be bonded. Clamp the surfaces together making sure to leave some adhesive in the joint. A gap of 1 mm or more will provide improved flexural and impact strength.
  • After the joint is clamped together, wipe off excess adhesive with a razor blade or squeegee using the masking tape as a gauge to slightly over fill the seam. Work the adhesive back and forth over the masking tape to make sure that the joint and any chips are filled.
  • Remove tape as soon as possible
  • The open time for the adhesive is approximately 10 to 15 minutes at normal room temperature. After the bead has cured (approx 30+ minutes) it can be scraped flush with a razor blade. Scraping the joint before it has cured will increase the effect of shrinkage in the joint and may leave the seam lower than the surrounding surface.
  • Application of an abrasive polishing compound (by hand or with a rotary polisher) after scraping will enhance the color and slightly smooth the adhesive. Top coating is not required.

Refer to MSDS for safety and handling information.

Always wear disposable gloves and eye protection when working with adhesives or polishing compounds.
