Curing Compounds & Cleaning of Concrete Floors

Concrete is best cured by ponding or full immersion in water, but on a real construction site, that's rarely practical. Getting curing right (and knowing how to remove a curing compound later) makes a measurable difference to the durability of the finished floor.

Why traditional curing methods often fail on site

Damp curing by spray or wet hessian often leads to repeated cycles of wetting and drying, which in turn causes micro-cracking on the surface. A high-performance, membrane-forming curing compound is the internationally adopted best practice; at a minimum, a non-specification film-forming spray-on liquid should be used instead of relying on hessian and hope.

Choosing and applying a curing compound

Samson offers CureSeal or ResinCure for specification compliance to ASTM C309, and FP Cure for general spray-on use.

Timing is critical: application should happen as soon after final set as practical. Applying it too early, before initial set, often leads to either flotation or dilution of the membrane, neither of which cures the slab correctly.

Once the curing compound has served its purpose, it needs to come off. Samson has dedicated chemical removal methods for this:

• FP Cure: pack size 5L / 25L / 200L, yield 8–10 m² per litre
• CureSeal or ResinCure: pack size 5L / 25L / 200L, yield 8–10 m² per litre
• PolyStrip (removes FP Cure): pack size 5L / 25L / 200L, yield 5–8 m² per litre
• Stripper A (removes CureSeal or ResinCure): pack size 5L / 25L / 200L, yield 5–8 m² per litre

Getting it specified correctly

For detailed technical data sheets and installation processes, request a Samson method statement for site instruction: it's a small step that avoids a costly re-do. Browse our curing, stripping & cleaning range or get in touch with our technical team.
