HARDTOP DM is a high-performance, non-metallic dry shake floor hardener formulated from a premixed blend of hydraulic cement, hard-wearing aggregates, and selected additives for optimum performance. Applied to fresh concrete by the dry shake method, it trowels easily into the surface, forming a dense, non-porous layer that is highly resistant to abrasion, impact, and petroleum-based products. HARDTOP DM creates a non-dusting, monolithic bond with the concrete base, is suitable for both internal and external use, and will not rust when exposed to moisture. Supplied ready-to-use, it ensures factory-controlled quality and is available in a range of colors to enhance the work environment.
Hardtop DM is broadcast onto stiffening fresh concrete in two stages at 3–5 kg/m² in total, floated in after each stage and cured under polythene.

Standards and test methods as referenced in the Hardtop Dm Technical Data Sheet. Values in the TDS are typical laboratory results under standard conditions.
Use 2–3 kg/m² for light and medium duty floors and 3–5 kg/m² for heavy duty floors. Coverage is approximate and subject to site conditions.
Apply it when the base concrete has stiffened so that light foot traffic leaves an imprint of about 3–6 mm, bleed water has evaporated and the surface still has a wet sheen. Applying too early, while bleed water is present, reduces the benefit.
Yes. Hardtop DM is for internal and external use, and its non-metallic aggregate will not rust when wet.
Hardtop DM is available in cement grey, brick red, brown and green.
Hardtop DM is supplied in 25 kg and 50 kg bags. It can be used within 12 months of production date if stored unopened in dry conditions away from direct sunlight and high humidity.
