How much methacrylic resin do I need for concrete?

Typical Coverage Rates for Concrete

For most standard absorbent concrete floors, expect to use between 40 and 60 grams of methacrylic resin per square metre. The exact requirement depends on porosity—older or rougher concrete will consume slightly more resin, while dense, smooth concrete may need less. As a reference, a 5 kg container of Resinstone methacrylic resin can cover up to 125 m² on well-prepared surfaces.

Application Guidance and Surface Preparation

Good preparation maximises coverage and final durability. Start by making sure the concrete is dry, free from dust, oil, and flaking material. Very porous or new concrete can benefit from a primer to prevent uneven absorption and ensure the resin forms a consistent protective layer. Primers such as Epoxyprimer are commonly used beneath the main resin layer on highly absorbent or newly laid concrete.

When Accurate Resin Estimation Matters

• Large areas: Small errors multiply, so double-check your maths for driveways, garages, or commercial spaces.
• Varying surface conditions: Older, more porous, or recently power-washed concrete will need the higher end of the coverage rate.
• Project budgeting: Knowing your quantities upfront avoids delays and unexpected costs.
