A Do-It-Yourself Guide to Concrete Curing Compounds

Curing is the process of maturing any mortar, such as screed plaster or concrete, to achieve its strength by sprinkling water or keeping wet sacks over it to avoid the water loss inside the mortar or concrete to maintain the Hydration process, avoiding cavities and reducing the risk of leakage while also increasing the durability of the structures.


  • The preferred and most regularly used equipment is a sprayer, which is typically employed in horticulture or pest management. Before using, the curing compound should be completely combined. To ensure even coverage, hold the spray nozzle approximately 450mm from the concrete surface and pass it back and forth.

Freshly poured concrete Horizontal surface

  • Curing ingredient is sprayed on after the initial surface shine has faded, which takes around 2 hours.

Precast or formed concrete (vertical surfaces)

  • After de-shuttering, immediately hose the concrete surface with clean water to eliminate any remnants of shuttering oil. Curing compound should be sprayed on as soon as the formwork is removed.

Surface Finishes

  • Once constructed, the membrane will remain on the concrete surface until it deteriorates. The time required for breakdown is determined by several parameters, including layer thickness, degree of exposure to weathering and UV light, foot traffic, and substrate porosity. Wherever further coatings/finishes are required, it is critical that the Curing membrane be completely removed using light wire brushing or other mechanical techniques.
