- Surface Preparation
HELMIBOND 6512 can be used on porous and non-porous surfaces free of moisture. Surface to be covered must be dry, clean and smooth. Any foreign materials present such as paint, grease, oil, pen markings, adhesive residues, etc. that may prevent a proper bond or migrate to the surface causing a stain must be removed. Adhesive can be used on all grades of concrete on, above or below grade in the absence of moisture. Installation of a 10 mil (0.010") or greater effective moisture retarder is recommended directly under all on and below grade concrete floors with its integrity insured. Concrete shall be prepared according to the recommendations outlined in ASTM F710 (Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring). Concrete floors shall be free from crazing dusting, spalling and any curing or sealing compounds. Concrete floors shall be tested for moisture according to the latest revision of ASTM F2170 (Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using in situ Probes) and ASTM F1869 (Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride). Wood floors must be double construction with a 1" minimum thickness, structurally sound, securely fastened and free from deflection/spring. Top layer of wood shall be underlayment grade plywood. Cracks and uneven surfaces must be filled with an approved cement-based patching compound.
- Application
Roller Application: Pour adhesive from container into a disposable paint tray. Apply a smooth even coat of adhesive to the substrate using a 3/8” nap roller. Keep roller wet throughout the application process. Do not allow adhesive to puddle. Replace rollers regularly and between applications to avoid adhesive drying on roller. Once applied, the adhesive must be allowed to dry to the touch and not transfer to finger. Dry time will take approximately 15 – 20 minutes depending upon substrate porosity, room temperature and humidity. Position flooring within 3-hours after the adhesive has dried to the touch. Once flooring is installed, immediately roll flooring in both directions with a 100 lb three-section roller. If the adhesive remains uncovered longer than the recommended 3-hours, a loss of bond strength may result. The installer should not apply more adhesive than can be covered with flooring within the 3-hour time frame.
Trowel Application: Apply adhesive with a 1/32” x 1/16” x 1/32” U-notch trowel. Spread adhesive evenly holding the trowel at a 60° angle. Replace trowels with worn notches. Do not re-notch worn notches. Once applied, the adhesive must be allowed to dry to the touch. Dry time will be dependent upon substrate porosity, room temperature and humidity. Position flooring within 4 hours after the adhesive has dried to dry to the touch.
Immediately roll flooring in both directions with a 100 lb three-section roller. If the adhesive remains uncovered longer than the recommended 4-hours, a loss of bond strength may result. The installer should not to spread more adhesive than can be covered with flooring within the 4-hour time frame. Post Installation Do not wash or begin maintenance procedures on the floor for a minimum of 5-days after installation to allow the adhesive to properly cure
- Clean-up
Remove wet adhesive immediately with a clean cloth dampened with mineral spirits, isopropanol or acetone. Cured adhesive is very difficult to remove. Do not apply solvents directly to flooring. Use caution when handling flammable solvents.
