Applications & Uses

- Application Area
- Use
KEMPEROL®AC SPEED FR membrane is suitable for exterior roofing and waterproofing applications including green, white, and blue roofs, plazas, balconies, terraces, park decks, and flashings. The membrane achieves Class A fire rating as part of an assembly in accordance with ASTM E 108 / UL 790.
- Limitations
KEMPEROL® AC Speed FR membrane may be applied when the ambient temperature is between 23°F (-5°C) and a maximum of 95°F (35°C). The substrate temperature must be a minimum of 5 degrees above the dew point.
Note: Extra caution should be taken in below freezing temperatures. The viscosity increases with falling temperature. Ensure sufficient positive airflow over freshly applied AC Speed FR material during entire curing period to facilitate complete cure.
- Yield
KEMPEROL® 120 Fleece: 60 ft2 (5.6 m2) per 15 kg work pack.
Note: All yields are approximate and may vary depending upon smoothness and absorbency of substrate.
- Surface Preparation
All surfaces must be free from gross irregularities, loose, unsound or foreign material such as dirt, ice, snow, water, grease, oil, release agents, lacquers, or any other condition that would be detrimental to adhesion of the primer and membrane. This requires careful preparation of existing horizontal and vertical substrates; cracks are filled, expansion joints are prepared, flashings are removed or modified, and termination points are determined. Substrates and penetrations are prepared to rigorous industry standards, and may require scarifying, sandblasting or grinding in some cases to achieve a suitable substrate.
- Priming
After substrate preparation, temporary watertightness can be achieved with the application of KEMPERTEC® AC Primer and Joint Sealant, and proper tie offs. KEMPERTEC® AC Primer may be brushed or rolled onto any clean and prepared surface. Allow primer to cure completely prior to application of the KEMPEROL® membrane.
- Mixing of Resin
Note: Prior to opening the containers of KEMPEROL® AC SPEED FR, wear appropriate safety glasses and protect hands and wrists by wearing gloves.
Step 1: Mix resin Component A with a spiral KEMPEROL® agitator, until the liquid is a uniform color, with no light or dark streaks present.
Step 2: Add the Catalyst Powder, Component B, to resin Component A and mix with the same agitator for 2 minutes or until the powder is completely mixed throughout the liquid resin. The amount of Catalyst Powder must be adjusted according to the temperature (see table).
Note: KEMPEROL® AC SPEED FR is extremely fast curing. Excessive mixing time reduces the available working time for the resin.
- Application
Step 1: After the Resin is mixed, using a KEMPEROL® roller nap or brush apply 1/2 of the resin liberally and evenly onto the surface in even stroke.
Step 2: Roll the KEMPEROL® Fleece directly into the resin, making sure the smooth side is facing up (natural unrolling procedure), avoiding folds and wrinkles. Use the roller or brush to work the resin into the fleece, saturating from the bottom up.
Step 3: Apply the remaining 1/2 of the resin to the top of fleece to complete the saturation. Rolling the final coat of resin onto the fleece should result in a glossy appearance. The fleece can only hold so much resin and all excess should be rolled forward to the unsaturated portion of the fleece. The correct amount of resin will completely saturate the fleece and no dry spots should be visible. Work wet membrane to avoid any blisters, openings, or lifting at corners, junctions, and transitions. Always assure full resin saturation of fleece.
- Surfacing
KEMPEROL® AC SPEED FR Membrane accepts KEMPERDUR® AC Finish in a smooth or aggregate finish for esthetic or mechanical wear. Additionally, KEMPERDUR® AC Traffic Coating system with an aggregate finish is available for pedestrian and vehicular traffic. KEMPEROL® AC Speed FR membrane must be fully cured prior to the application of a coating.
