Strong Bond 
Acrylic bonding agent and admixture
Strong Bond is an acrylic admixture and bonding agent designed to improve the adhesion and durability of concrete, masonry, stucco, terrazzo and Portland cement-sand mixes to horizontal and vertical concrete and other surfaces. May contribute to LEED credits.
- Improves the flexural strength, bond strength and impact resistance of mortars and concrete.
- Concrete and mortar fortified with STRONG BOND exhibit excellent resistance to cycles of freezing and thawing and to penetration of chloride ions.
- Minimizes cracks in concrete, stucco and plaster when used as an admixture
- Eliminates the need for separate air entraining agents
- VOC compliant. VOC content: <5g/l
Application
- Surface Preparation: Ensure substrates are mechanically abraded to remove unsound concrete, ensuring a dust-free surface with adequate profile for mechanical lock. The substrate should be saturated-surface-dry (SSD) without standing water.
- Mixing and Application: Vary mix designs to meet specific job requirements, adjusting sand, cement, and Strong Bond ratios to achieve the desired physical properties. For bond coats, a slurry consistency is recommended, ensuring thorough coverage and attention to detail.
- Admixture Dilution: Dilute Strong Bond up to 3:1 with water for general applications, with more concentrated mixtures offering increased durability.
Packaging
Available in 55-gallon drums, 5-gallon pails, and 1-gallon jugs, providing flexibility for project scales and requirements.
Shelf Life
Strong Bond has a shelf life of 1 year from the date of manufacture when stored properly and must not be allowed to freeze.
Test Data
- Sets initial bond within 50 minutes and achieves final set within 80 minutes at 70°F.
- Exhibits impressive compressive strength development over time, achieving up to 5500 psi at 28 days.
- Demonstrates high bond strength and excellent freeze-thaw resistance, indicating durability in challenging environments.
