- Substrate and ambient temperatures MUST be between 50F-95F (10C-35C).
- DO NOT apply in rain, or if rain is expected within 6 hours.
- Verify substrate is free of bond-inhibiting or bond breaking materials such as curing compounds and dust. We recommend to power wash solely with water and no chemical additives.
- Repair all cracks and seal surface from running water and contaminants prior to application.
- Do not apply over unprimed galvanized steel.
- Contact Technical Services Department (1-866-607-6826) for applications where the product will be exposed to chlorinated water.
- All substrates/surfaces must be structurally sound, dry, solid, and stable. The surface shall be clean of dirt, oil, and grease and free of loose impediments.
- Power wash with water solely and no chemical additives is recommended.
- The surface must be dry (NOT WET).
- Mechanically clean the area to be sealed (use stiff wire brush or equivalent)
- Rubberseal Roll On must be thoroughly mixed using a paddle mixer at a SLOW(approximately 100rpm) speed.
- Caution: Mixing at medium or high speed may cause separation of the polymer, creating small chunks of material in the product.
- Rubberseal Roll On must be mixed for 5 minutes prior to installation, until material is entirely homogeneous.
- If material sits more than 3 hours, remix for 5 minutes.
- Do NOT add water, solvents, or any other materials to the product.
- Rubberseal trowel on does not need to be mixed prior application.
Step 3 – Product Application
- Rubberseal Roll On may be applied using a standard 3/8” (8mm) nap roller with standard cage in small areas or a brush.
- Roll material onto substrate/surface and spread evenly to achieve a thorough depth and film consistency of at least 15 mil WFT (wet film thickness) on the first coat.
- Remaining coats may be applied as soon as the previous application has dried from the brown shade, to the black (typically 60 minutes at 70F (21C) and depending on the application.
- Total amount of coats, depends on the application. We recommend applying at least 40 mils thickness in all applications, each coat gives you approx 5 mils thickness. As thicker is the application, membrane last longer.
Step 4 – Curing
- The product will cure for flood testing in 24 hours and will be fully cured in 72 hours at 70F (21C).
- Equipment may be cleaned using water or mineral spirits.
- Use Baby Oil or WD-40 to clean Rubberseal off your hands or other material.
- Use Rubber Gloves to put on Geotextile
For Repairing an existing Application:
Step 1: Repeat steps 1 and 2 of the general application process and overlap the damaged area that has been trimmed and cleaned.
Step 2: Apply a patch of Rubberseal Geotextile Fabric Roll or suitable geotextile for reinforcement over the repair area. Use Rubber Gloves to apply the Geotextile.
Step 3: Prior to application of coats on top of existing Rubberseal™ coatings, clean by rinsing thoroughly with fresh water.
Step 4: You can proceed with the application using a standard 3/8” (8mm) nap roller with standard cage in small areas or a brush.
Step 5:Curing time is minimun 72 hours at 70F (21C)
Step 6: Cleaning equipment using water or mineral spirits. Clean your hands with baby oil or WD-40
For Reinforcing or repair surface:
When addressing out of plane areas, cracks, joints, or where requiring reinforcement or repair, utilize a geotextile such as Rubberseal Geotextile Fabric Roll 50’x10″ (Available in our store). Contact Technical Services to determine the suitable geotextile for the specific jobsite requirement.
Application using Rubberseal Geotextile:
Step 1: Saturate the Rubberseal Geotextile Fabric Roll grade and place the material.
Step 2: Wait about 2 hours until dry, and apply topcoat.
Step 3: Alternately apply a 20 mil coat of Rubberseal™ roll grade and immediately place the fabric and roll lightly, to ensure full contact between the geotextile and the initial coat of
Rubberseal™ or the concrete.
Step 4: Wait about 2 hours and apply the final build of Rubberseal™ Roll Grade.
