HDB flooring: Steps for a successful self-levelling concrete application

Self-levelling concrete is a cementitious mixture that flows easily to create a smooth, level surface. Its used in HDB flats to correct uneven subfloors before installing the final flooring material.

The key steps include: preparing the subfloor by cleaning and priming, mixing the self-levelling compound according to the manufacturers instructions, pouring the mixture evenly, using a spiked roller to remove air bubbles, and allowing it to cure properly.

Thoroughly clean the existing floor, removing any debris, dust, or loose particles. Apply a suitable primer to promote adhesion between the subfloor and the self-levelling compound.

Youll need a mixing bucket, drill with a mixing paddle, spiked roller, gauge rake (optional), primer, and appropriate safety gear like gloves and a mask.

Curing time varies depending on the product and environmental conditions, but typically it takes between 24 to 72 hours. Always consult the manufacturers instructions for specific curing times.
