Curing Compounds for Concrete – Seal & Protect Fresh Pours with Water, Solvent & Resin-Based Formulas

Curing compounds are formulated to slow the evaporation of moisture from building supplies such as  freshly poured concrete, allowing the cement to fully hydrate and reach its designed strength. Inadequate curing can lead to premature drying, surface cracking, shrinkage, and reduced durability - all of which can be mitigated by timely application of a suitable compound. These products are commonly used in large-scale slabs, pavements, precast units, and structural pours where water curing is impractical or inconsistent. Our selection includes water-based acrylics for cleaner indoor application, solvent-based compounds for fast curing in colder conditions, and resin-based formulas with enhanced sealing properties. Many offer temporary film-forming benefits while allowing the surface to remain breathable. Coloured or pigmented variants help ensure uniform application and minimise missed areas, particularly under site lighting or during rapid work phases.

Curing compounds are typically applied by low-pressure sprayer directly onto the surface after the final finish has been completed and bleed water has evaporated. They form a film that prevents moisture escape during the critical curing window, helping the concrete develop strength, abrasion resistance, and stability over time. Some products are also compatible with subsequent surface treatments, paints, or screeds once fully broken down or removed. From internal slabs to exposed structural pours, using a curing compound supports long-lasting concrete performance. Whether you're working on a new floor, bridge deck, tank base, or retaining wall, our curing compounds provide reliable protection against early age drying and are supported by detailed technical guidance to suit a range of climates, mixes, and application methods.

Curing Compounds FAQs

When should I apply curing compound to concrete?

Apply curing compounds immediately after the surface is finished and the bleed water has evaporated. Applying too early can trap excess moisture on the surface, while applying too late may allow premature drying. Conditions such as temperature, wind, and humidity may affect the ideal timing.

Can curing compounds be used on interior and exterior concrete?

Yes. Water-based compounds are often preferred indoors due to their low odour and reduced VOC content. Solvent-based or resin-based versions are better suited for outdoor use, particularly in colder or windier conditions. Always choose a formulation suited to your environment and ventilation.

Do curing compounds affect adhesion of coatings or screeds?

Some curing compounds may interfere with the adhesion of surface treatments such as epoxy coatings or levelling screeds. Where further finishes are planned, choose a compatible curing compound or ensure it can be removed easily before the next stage of installation.
