Description
ForzaBOND™ OA75 is a hardwood and bamboo adhesive and moisture control membrane all in one. This adhesive formulation maintains long term durability and moisture control properties, and it is easy to spread and clean off of prefinished flooring before and after cure. This adhesive has low VOC’s (as measured per EPA Method 24) and does NOT contain any water.
Applications
It may be used to adhere all engineered, solid, bamboo, cork, and parquet.
It may be used over all properly prepared substrates common to hardwood flooring installations including; concrete, plywood, OSB, well bonded vinyl/VCT and ceramic tile, cement backer board, gypsum underlayments (dry, above grade), cement patch/underlayments, radiant-heat flooring, and properly prepared terrazzo.
Benefits
- Easy spread & clean
- Subfloor moisture protection
- Low odor & VOC
How to Use
- The installation begins with a starter row secured to the subfloor; the starter row provides a stationary point to push against so flooring doesn’t move during installation.
- Once the starter row is secured, apply adhesive/membrane to substrate using the appropriate trowel. See the chart on last page for proper trowel selection.
- Flooring is to be installed using a “Wet-Lay” method of installation.
- For a “Wet-Lay” type of installation, spread the adhesive and begin to install the flooring immediately.
- Periodically lift boards immediately after installation to ensure proper slab coverage and transfer to the back of the flooring. If a thin skin forms on the adhesive on the slab prior to installation of the flooring, it may be possible to re-trowel the adhesive and obtain proper coverage and transfer. Re-trowel 90° to the ridges, and if no sign of the original trowel marks remains, install additional flooring and check coverage and transfer.
- Adhesive that has cured too much prior to installation of the flooring must be mechanically removed and fresh adhesive applied.
- Although it is relatively easy to remove OA75 adhesive from the face of prefinished hardwood even after cure, it is recommended to clean with a non-abrasive towel as you work prior to cure.
- After a few rows have been installed, and as you move across the room, tape the boards together using removable 3M #2080 Blue tape to prevent boards from sliding and to secure close-fitting joints.
- Flooring that is not flat should be tacked, weighted, or rolled to ensure proper contact between the flooring and substrate.
Plywood Over Concrete: - Score 4′ x 4′ or 2′ x 8′ sheets of 3/4″ exterior-grade plywood on the backside every 8″ to 10″ by using a circular saw and cutting onehalf the thickness of the plywood; “scoring or kerfing” takes the tension out of the plywood and helps to prevent possible warping or curling.
- Using a recommended trowel, apply adhesive/membrane to substrate and then set plywood into the wet adhesive/membrane.
- For moisture protection, ensure 100% coverage and transfer.
- Allow the adhesive/membrane to fully cure before nailing or using OA75 adhesive/ membrane to install flooring.
- Make sure that nails do not penetrate through the OA75 membrane.
