3 Room HDB: Ensuring proper material installation for longevity (how_to)

Ensure the contractor uses a self-levelling screed, checks the moisture content of the existing slab, and applies a bonding agent for optimal adhesion and a smooth, even surface.

Opt for waterproofing membranes with good elasticity and chemical resistance. Ensure proper surface preparation and apply multiple coats, paying close attention to corners and pipe penetrations.

Use PSB-approved wiring with the correct gauge for your appliances. Hire a licensed electrician to ensure proper installation, grounding, and adherence to Singapores electrical safety standards.

Choose high-pressure laminates (HPL) for better scratch and heat resistance. Ensure the substrate is smooth and properly bonded. Use edge banding to prevent moisture from seeping in.

Use weather-resistant sealants and flashing around the window frame. Ensure proper drainage to prevent water from pooling, and consider a slight outward slope for water runoff.

Use a suitable adhesive based on the tile type (ceramic, porcelain, etc.). Ensure the substrate is level and clean. Leave adequate grout lines and use a quality grout sealant to prevent water penetration.

Select a paint suitable for Singapores humid climate. Ensure proper surface preparation, including cleaning, sanding, and priming. Apply multiple thin coats rather than one thick coat for better adhesion.
