10°C / 50°F or above 30°C / 86°F. An application
below/above these temperatures will result in decreased
product workability and cure times.
85% during application and during curing process.
The substrate temperature must be at least 3°C (5.5°F)
above measured dew point.
Humidity content of substrate must be < 4% at time of
application.
Do not apply on porous surfaces where a transfer of
humidity may occur during the application.
Applying this product on a substrate without a moisture
barrier may risk delamination due to hydrostatic pressure.
Freshly applied product must be protected against
moisture, condensation, and water for at least 48 hours.
Surface discoloration of product will occur upon prolonged
exposure to UV rays.
Exposure during the curing stage of the coating to the byproducts of propane combustion may cause discoloration
(amine blushing).

How EverFlow EF-135 Works
EF-135 cures through a chemical reaction between its two components.
Process Overview
- Mix Part A (resin) and Part B (hardener)
- Apply directly into cracks or joints
- Rapid curing begins immediately
- Material hardens into a solid structural repair
Because of its fast cure time, it must be applied quickly after mixing.
How to Apply EverFlow EF-135
Step 1: Surface Preparation
- Clean the crack thoroughly
- Remove dust, debris, and contaminants
- Ensure the surface is dry
Step 2: Mixing
- Mix components according to manufacturer ratio
- Use a low-speed mixer or hand mix
- Mix only what you can apply quickly
Step 3: Application
- Apply directly into the crack
- Use a trowel or putty knife
- Level the surface evenly
Step 4: Curing
- Allow product to cure (minutes)
- Grind or sand if needed
- Proceed with coating application
