Megapoxy LVS: A Product Overview
When you need to guarantee the performance of a coating system, Megapoxy LVS provides the solution. This is a high-performance, two-component, low-viscosity epoxy resin engineered as a penetrating sealer and primer. Its ultra-low viscosity allows it to dive deep into porous substrates like concrete, timber, and brick, creating a permanent, waterproof, and chemically resistant barrier. This isn't just a sealer; it's a structural hardener.
As the specified primer for Megapoxy Floor Coating products, LVS is the smart choice for preventing delamination, stopping concrete dusting, and ensuring a tenacious bond. It delivers predictable, first-time-right performance, removing the risk of costly failures and protecting your margins.
80MPa
Verified Compressive Strength (ASTM D695) — creating a tough, resilient surface superior to concrete.
Core Features & Specifications
- Ultra-Low Viscosity: A 90cps mixed viscosity ensures deep, penetrating sealing of porous substrates rather than just sitting on the surface.
- Superior Bond Strength: Achieves a bond stronger than the substrate, delivering >3MPa on concrete (concrete failure) and 20MPa on steel.
- High Compressive & Tensile Strength: Cures to a tough 80MPa compressive and 40MPa tensile strength, significantly hardening and toughening surfaces.
- Simple 2:1 Mix Ratio: A straightforward 2 Parts A to 1 Part B by volume mix ratio ensures predictable, reliable performance on site.
- Fast Thin Film Cure: Cures as a thin film in just 4 hours at 25°C, allowing for faster application of top coats and reducing project downtime.
- Waterproof & Chemically Resistant: Provides a permanent, durable barrier against water ingress and chemical attack.
The Megapoxy LVS Advantage
- The System-Matched Primer: Engineered as the primer for Megapoxy floor coatings, it locks into the substrate, removing the risk of delamination and costly callbacks.
- Stops Dusting & Seals: Penetrates and seals porous concrete, stopping dusting permanently and providing a tough, waterproof barrier for floors, walls, and tanks.
- Hardens & Toughens Substrates: Don't just coat a weak surface; Megapoxy LVS reinforces it. Its high strength improves the durability of the entire system.
- Job-Site Ready & Efficient: Easy to mix by hand and apply by brush or roller, with a practical 30-minute work time and excellent coverage rates.
Adheseal tips for using Megapoxy LVS
Scenario: Applying to Damp Concrete
Potential Outcome
Applying to a damp or wet substrate will cause poor adhesion, blistering, and certain delamination of the sealer and any subsequent topcoats.
Adheseal Best Practice
Megapoxy LVS must be applied to thoroughly dry substrates. After preparation (grinding/washing), allow concrete to dry for at least 24 hours. Always conduct a moisture test to ensure a first-time-right result.
Scenario: Incorrect Application Thickness
Potential Outcome
Allowing the sealer to pool in thick sections prevents proper curing, can trap solvents, and creates an uneven, problematic surface for top coating.
Adheseal Best Practice
This product is designed to penetrate. Apply it as thinly as possible. Use a roller or brush and wipe up any excess material that pools. You are sealing *into* the substrate, not building a thick film on top of it.
Applications in Practice: Trade Scenarios
For Flooring Contractors: Priming Floors for Epoxy Coatings
The Professional's Challenge
Ensuring a high-performance epoxy topcoat doesn't delaminate, blister, or fail due to substrate porosity, dusting, or poor adhesion. Callbacks are not an option.
The Adheseal Solution
Use Megapoxy LVS as the system-matched primer. Its 90cps viscosity penetrates deep, sealing the concrete and creating an unbeatable bond (>3MPa). This eliminates dusting and porosity issues. Success means a defect-free finish and zero costly callbacks.
Best Practice Note
Coverage is key to profitability. On a dense, steel-trowel finish, expect approx. 150m² per 15L kit. On a porous, wood-float finish, expect approx. 75m² per 15L kit.
For Asset Maintenance: Sealing & Waterproofing Concrete Tanks
The Professional's Challenge
Protecting internal concrete tank walls from water ingress and chemical attack, while hardening the surface to prevent erosion and contamination.
The Adheseal Solution
Megapoxy LVS penetrates and seals the concrete, providing a durable, waterproof, and chemically resistant barrier. Its high compressive strength (80MPa) and tensile strength (40MPa) create a tough, non-porous surface. Success means long-term asset protection.
Best Practice Note
For sealing applications, a minimum of two coats is required. Ensure the substrate is completely dry before application and adhere to all confined space safety protocols due to flammable vapours.
Frequently Asked Questions
What is the mix ratio for Megapoxy LVS?
The correct mix ratio is 2 Parts A to 1 Part B by volume. It is essential that this ratio is measured accurately and that the two parts are mixed thoroughly. Inaccurate ratios or poor mixing will result in the system not curing correctly and will lead to poor performance.
How do I apply Megapoxy LVS and what is the coverage?
Apply by brush or roller. The product must be applied as thinly as possible and should not be allowed to pool; wipe up any excess. Coverage depends on porosity: a dense, steel-float concrete finish will achieve approx. 150m² per 15L kit. A porous, wood-float concrete or brick finish will achieve approx. 75m² per 15L kit.
How long does Megapoxy LVS take to cure or recoat?
At 25°C, Megapoxy LVS has a work time of 30 minutes. As a thin film, it will be tack-free in approximately 4 hours, allowing for recoat or application of a topcoat. It reaches a minimum cure (ready for light traffic) in 24 hours. In colder conditions (15°C), the minimum cure extends to 48 hours.
Is Megapoxy LVS flammable or hazardous?
Yes, this is a Class 3 Flammable Liquid and must be handled as Dangerous Goods. Keep away from all ignition sources (flames, sparks, pilot lights), use non-sparking tools, and ensure high ventilation. Furthermore, Part B is Class 8 Corrosive and can cause severe skin burns and permanent eye damage. Always read the SDS and wear full PPE, including an organic vapour respirator, gloves, and eye protection.

Primer Requirements
N/A - This product is the primer/sealer.
This is a dense surface. Expect coverage around 150m² per 15L kit.
Timber
Surface Preparation
