Managing water ingress, subterranean dampness, and surface porosity across concrete slabs, retaining walls, and timber structures requires more than standard off-the-shelf sealers. In humid, moisture-heavy environments like South East Queensland and across coastal Australia, selecting the correct epoxy viscosity and curing system is critical to prevent coating failure.
The EpoxyPro EP30 Series is a premium, Australian-owned, 2:1 solvent-free epoxy waterproofing and priming system engineered to handle demanding residential, trade, marine, and civil applications. Whether you need deep slab saturation, vertical wall bridging, or a coating that bonds directly to damp concrete, there is a dedicated EP30 formulation designed for the task.
Quick Comparison: Which EP30 Formula Do You Need?
| Formula | Specialty Focus | Viscosity | Primary Substrates & Applications |
|---|---|---|---|
| EP3010 | Deep Penetration & Sealing | Low (~809 cP) | Porous concrete slabs, basements, balconies, decks, timber & stone priming. |
| EP3020 | High-Build Vertical Membrane | Mid-High (~13,700 cP) | Retaining walls, planter boxes, crack filling, high-build floor priming. |
| EP3030 | Wet & Damp Surface Bonding | Low (~1,150 cP) | Damp basements, wet retaining walls, water tanks, sumps, damp concrete repairs[. |
1. EpoxyPro EP3010 — Deep Penetrating Sealer & Primer
EP3010 is an ultra-clear, low-viscosity system (~809 cP) designed specifically to soak deep into porous substrates rather than just sitting on top. It fills micro-capillaries within concrete, masonry, and timber to create an impenetrable, self-priming moisture barrier.
- Ultra-Low Viscosity: Maximum penetration into porous slabs and masonry.
- Multi-Substrate Versatility: Excellent adhesion to concrete, timber, stone, and GRP products.
- Self-Priming: Eliminates the need for separate priming coats before top-coating.
2. EpoxyPro EP3020 — High Build Vertical Waterproofing & Primer
When working on vertical surfaces like retaining walls, planter boxes, or substrates with hairline cracks, low-viscosity resins can run off before building a protective layer. EP3020 features a higher viscosity (~13,700 cP) with engineered flexibility to stay in place, bridge gaps, and accommodate substrate thermal expansion.
- Thicker Film Build: Ideal for vertical walls, wet rooms, and retaining structures.
- Flexible Membrane Curing: Resists cracking caused by minor structural movement.
- Heavy Duty Protection: High resistance to moisture, salts, oils, and chemicals.
3. EpoxyPro EP3030 — Damp & Wet Surface Specialist
Standard epoxies fail when applied to moist concrete because water interferes with the chemical curing process. EP3030 uses a specialized curing agent designed to bond directly to properly prepared wet or damp substrates. It is the ultimate problem solver for flood recovery, damp basements, or project sites where waiting for total dryness would cause severe delays.
- Applies to Damp Concrete: Works where standard primers fail due to surface moisture.
- Reduces Site Delays: No need to wait days for wet slabs to dry completely before sealing.
- Commercial & Civil Tough: Excellent choice for water tanks, sumps, basements, and retaining walls.
