EpoxyPro EP3020 High Build Waterproofing & Priming Epoxy Resin 2:1

EP3020 is a mid-viscosity, solvent-free, two-part epoxy resin system designed for waterproofing, priming, and structural sealing applications. Formulated to provide excellent adhesion, moisture resistance, durability, and flexibility, it is ideal for concrete, masonry, timber, stone, and composite substrates where a thicker film build is required. When cured, EP3020 produces a durable clear/amber finish with good flexibility to accommodate minor substrate movement and thermal expansion.

Unlike low-viscosity penetrating systems, EP3020 can be used as both a waterproofing membrane and a high-build primer. Its higher viscosity helps seal porous surfaces, reduce substrate absorption, and create a durable foundation for subsequent coating systems.

Key Applications

• Waterproofing concrete, masonry, stone, and timber
• High-build epoxy primer for porous substrates
• Crack filling and surface defect remediation
• Retaining walls, balconies, wet areas, and planter boxes
• Protective barrier coatings and maintenance applications
• Marine and industrial waterproofing projects

Technical Highlights

• Mix Ratio: 2 Parts Resin: 1 Part Hardener (by volume)
• Mid to High Viscosity (13,700cP)
• Light amber appearance when cured
• Good flexibility for improved crack resistance and substrate movement
• Excellent adhesion to concrete, timber, masonry, stone, and composites
• High-build waterproofing and sealing properties
• Suitable as both a primer and waterproofing coat
• Excellent moisture and chemical resistance
• Durable, long-lasting protective barrier

Why Choose EP3020?

• Waterproofs and primes in a single system
• Higher build than penetrating epoxy primers
• Good flexibility to accommodate minor movement and reduce cracking
• Helps seal porous surfaces and reduce pin-holing
• Excellent gap-filling and surface sealing properties
• Suitable for commercial, industrial, marine, and residential applications

Perfect For

Waterproofing, priming, concrete sealing, retaining walls, balconies, wet areas, masonry protection, marine maintenance, industrial coating applications, and substrates requiring a durable waterproof barrier with good flexibility.
