Wood Flooring Will Never Be More Secure!

W.W. Henry is pleased to announce a new generation wood adhesive, HENRY SureLock™ 1171, designed for installations of engineered wood and parquet. HENRY SureLock 1171 is a significant advancement in wood floor adhesive technology that delivers an optimum balance of installation and performance characteristics.

HENRY SureLock 1171 will set new standards for the expectations of adhesives used for engineered wood and parquet floors. Incorporating Henry’s new SureLock technology, HENRY 1171 delivers higher ultimate bond strength and increased resistance to subfloor moisture, while maintaining the flexibility needed for long-term installation integrity. But what do these extraordinary features mean to the installation professional?

Developed With No Compromise
Historically, early generations of latex-based adhesives have had good initial grab while sacrificing bond strength. Conversely, adhesives with higher bond strength sometimes sacrificed initial grab. HENRY SureLock 1171 combines the benefit of strong initial grab with higher early bond strength development and ultimate bond.

HENRY SureLock 1171’s aggressive early grab and rebond holds the wood floor in place during the installation. A key characteristic of the new SureLock technology is the early strength development. The adhesive develops strength quickly in the first 24 hours, helping to minimize end lifting and hollow spots.

Easy to Use - With The Optimal Working Time For Wood Installations
Many wood adhesives can be difficult to use. HENRY SureLock 1171 trowels nicely, and is easy to clean up afterwards. Wood can be set into HENRY SureLock 1171 immediately after troweling, but works best with a few minutes of open time. W.W. Henry has achieved the perfect balance between working time and bond development, giving the installer an ideal timeline for installing wood. The optimal recommended maximum working time is approximately 30 minutes, depending on temperature and humidity.

Higher Ultimate Bond Strength & Flexibility
HENRY SureLock 1171 delivers higher bond strength combined with greater flexibility and elongation versus prior generations of latex-based wood adhesives. The bond strength of the adhesive required to adhere engineered wood has always been a question. Higher bond strength, on its own, does not tell the whole story, and too much or too little can cause problems.

Some adhesive technologies provide extremely high bond strength, but lack flexibility. Subfloor movement can then cause either the wood or adhesive to fracture. These adhesives are also very difficult to remove. On the other side of the spectrum, some latex-based adhesives have excellent flexibility, but lower bond strength.

HENRY SureLock 1171 has higher bond strength, but retains elongation and flexibility characteristics. This helps it to withstand seasonal and dimensional changes within the wood. The contractor, installer and floor owner can feel confident in knowing HENRY SureLock 1171 will keep the wood installation secure.

Enhanced Moisture & Alkali Resistance
The growing popularity of wood has increased the demand for installing wood directly over concrete, driving an increased need for adhesives that will resist the influence and impact of subfloor moisture. HENRY SureLock 1171 was developed to withstand higher levels of moisture.

So, how much moisture in the subfloor will HENRY SureLock 1171 withstand? More than most wood flooring structures can handle! Testing has confirmed that the adhesive will continue to bond even as wood manufacturer guidelines for moisture is exceeded and damage starts to appear in the wood. While W.W. Henry continues to support the wood manufacturers recommendations for moisture limits, isn't it reassuring to know that HENRY SureLock 1171 will continue to perform even when the wood flooring capabilities are exceeded?

Solvent-Free & Low Odor
W.W. Henry’s commitment to lowering the impact of adhesives on users is evident in HENRY SureLock 1171. This low VOC, solvent-free and low odor adhesive is a member of Henry’s Next Generation line of environmentally preferred products.

SystemOne™ - The Installation System Approach
The two biggest obstacles to successful wood installations are correct subfloor preparation and moisture in the subfloor. Who better than Ardex to help the contractor and installer with doing the job right the first time? HENRY SureLock 1171 is a member of the Ardex Engineered Cements and W.W. Henry SystemOne™ family of products.

HENRY’s Best 10-Year Warranty HENRY SureLock 1171 comes with HENRY’s Best 10-Year Warranty, stating that 1171 will not break down or lose its cohesive strength due to a manufacturing or formulation defect for 10 years from the date of installation.
