Concrete Glue

Re-emulsifiable bonding agent

Concrete Glue is a versatile, re-emulsifiable polyvinyl acetate (PVA) emulsion used as an admixture and bonding agent. It is designed to bond new concrete, underlayments, masonry, stucco, terrazzo, and Portland cement/sand mixes to both horizontal and vertical concrete surfaces. It is suitable for interior and exterior use, except in conditions of constant moisture, hydrostatic pressure, or continuous water saturation.

  • Re-emulsifiable/Rewettable: Ensures strong re-bonding capabilities.
  • Superior Adhesive Strength: Provides excellent bonding for various substrates.
  • Enhanced Durability: Increases durability, adhesion, and curing when used as an admixture.
  • Flexible Application Timing: Allows for delays between primer application and subsequent topping or underlayment without losing effectiveness.
  • VOC Compliant: Has an actual VOC content of 0 grams per liter.

Application

Concrete Glue is primarily used as a primer/bonding agent for underlayments, plaster, and stucco. It is also effective as a bonding admixture for cement-based mortars and stucco, enhancing their adhesion and durability.

Preparation and Application

  • Surface Preparation: Surfaces must be clean, structurally sound, and free of contaminants. Pre-dampen surfaces before application.
  • Application Method: Apply using a brush, broom, or sprayer. Ensure even coverage of 150-250 square feet per gallon, depending on surface porosity. The product remains tacky when dry, and care should be taken to avoid dirt accumulation.
  • Drying Time: Typically 2-3 hours at 70°F, though poor ventilation can extend this time.

Mixing and Use as an Admixture

  • Replace half of the mixing water with Concrete Glue when preparing cement-based mortars or stucco to enhance their properties.

Packaging

  • Available in 55-gallon drums, 5-gallon pails, and 1-gallon jugs (sold in cases of four).

Shelf Life

  • Store in a cool, dry place away from direct sunlight.
  • When stored properly in its original tightly closed container, Concrete Glue has a shelf life of 1 year.

Standards

  • ASTM C1059 – Latex Agents for Bonding Fresh to Hardened Concrete, Type I
  • ASTM C932 – Surface-Applied Bonding Compounds for Exterior Plastering
