- Composition & Materials
A monolithic membrane is created in the field by applying the KEMPEROL® 1K-LF Flashing singlecomponent, cold liquid-applied silane based moisture-cure resin with KEMPEROL® premium polyester reinforcing fleece. Membrane must be applied using premium fleece (available with a 13 inch nominal width).

- Cure Method
- Use
KEMPEROL® 1K-LF Flashing membrane is suitable for flashing and repair in both interior and exterior applications including roofs, plazas, planters, foundations, mechanical rooms and other waterproofing applications.
- Limitations
KEMPEROL® 1K-LF Flashing may be applied when the ambient temperature is 41°F (5°C) and rising, and the substrate temperature is a minimum of 5 degrees above the dew point. The maximum application temperature is approximately 104°F (40°C).
Note: Viscosity increases with falling temperature.
- Yield
KEMPEROL® Premium 165 Fleece: 25 ft2 (2.32 m2) per 6.5 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 the adhesion of the membrane. This requires careful cleaning and preparation of existing surfaces. Existing membranes should first be cleaned with a solvent cleaner, such as KEMPERTEC® Klean or MEK, and abraded with a 60 grit sand paper. Concrete and metal surfaces should be thoroughly cleaned and abraded with a hand grinder.
- Priming
After surface preparation, the following substrates do not require priming; Existing cold fluidapplied membranes, Modified Bitumen membranes, PVC single-ply membranes, concrete, brick, CMU, wood and metal. For all other surfaces please refer to the Kemper System Substrate Primer Selection Table, found in the Technical Manual.
Note: Prior to opening the containers of KEMPEROL® 1K-LF Flashing Resin, wear appropriate safety glasses and protect hands and wrists by wearing gauntlet-type neoprene gloves.
- Mixing of Resin
Mix resin with a spiral agitator until the liquid is a uniform color.
- 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. Covering one working area at a time.
Step 2: Roll the KEMPEROL® Premium 165 Fleece directly into the Resin, making sure the perforations are facing upward (natural unrolling procedure), avoiding folds and wrinkles. Use the roller or brush to work the resin into the fleece, saturating from the bottom up. The appearance of the fleece should be saturated with no white spots. White spots are indications of unsaturated fleece or the lack of adhesion. It is important to correct these areas before proceeding.
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 with no dry fleece visible. Work wet membrane to avoid any blisters, openings, or lifting at corners, junctions, and transitions. Always assure full resin saturation of fleece.
Note: On flashing applications use the 13.8” fleece with 6” of the reinforcement fleece on the horizontal surface.
- Surfacing
KEMPEROL® 1K-LF Flashing membrane may be recoated after a minimum of 24 hours. Ensure the membrane is fully cured before recoating

Storage & Handling
- Storage
Always store in cool and dry location. Do not store in direct sunlight or in temperatures below 41°F (5°C) or above 80°F (27°C). Approximate shelf life 12 months with proper storage.
For best use, 24 hours before application, the material is to be acclimated at temperatures between 65-70°F (18-21°C).
- Disposal
Cured KEMPEROL® 1K-LF Flashing resin may be disposed of in standard landfills. This is accomplished by thoroughly mixing the product with 1/4 cup (60ml) of water and waiting until fully cured. Uncured KEMPEROL®1K-LF Flashing resin must be handled in accordance with local, state and federal regulations. Do not throw uncured resin away.
