BioCoat™ SWaE250
Water-Based Epoxy Primer | Two-Component
BioCoat SWaE250 is a bio-based, water-based, two-component epoxy primer engineered to provide strong adhesion and reliable surface preparation across a wide range of substrates. Designed for ease of use and professional performance, it delivers excellent bonding strength on concrete, ceramic, wood, and metal, making it a versatile primer for multi-surface coating systems.
With low VOCs and no odor, BioCoat SWaE250 supports improved indoor air quality and is well suited for occupied or compliance-driven environments. Its fast dry time and water-reducible formulation help streamline application while maintaining the durability expected from industrial epoxy primers.
Designed for Reliable System Performance
BioCoat SWaE250 creates a durable, uniform base layer that enhances adhesion between substrates and subsequent epoxy or polyurethane coatings. Its low-viscosity, water-based system allows for easy application and penetration, supporting consistent coverage and long-term performance in flooring and protective coating systems.

Directions For Use
Surface Preparation:
- For high strength structural coatings, remove surface contaminants such as paint, oxide films, oils, dust, mold release agents and all other surface contaminants.
- Use gloves to minimize skin contact.
Mixing Instructions for a 5-Gallon Kit:
- Full cure in 5 days.
- Mix Part A well prior to use. Use a paint stick or a drill mixer.
- Add all of Part B to Part A. Mix 5 minutes using a drill mixer.
- Add the required amount of water to Part A (as per label instructions).
- Mix for 5 minutes using a drill mixer.
- Add the entire content of the Accelerator to Part A if a faster dry is desired.
- Mix for 5 minutes using a drill mixer.
- Apply with brush, roller or sprayer to substrate.
- Apply coating at 5 wet mil to 6 wet mil thickness
- Coating will be dry to touch in 3-4 hours when using the included Accelerator.
