Product Range
| Product | Best For |
|---|---|
| SL400 20kg Self-Levelling Compound | The go-to affordable leveller for internal floors — pours 1-40mm in a single application, walkable in 2-3 hours, ready for floor coverings in 24 hours. Ideal under vinyl, carpet, timber, or tiles in residential and commercial settings. The most cost-effective choice for standard internal levelling. |
| SLE500 FLEX 20kg Flexible Timber Floor Levelling | Purpose-built for timber substrates — flexible formulation that moves with the floor without cracking. Use this whenever you're levelling over timber, particle board, or plywood subfloors. |
| SLE 500 20kg Premium Self-Levelling Compound | The premium step-up from SL400 — works both internal and external, pours up to 50mm, cures to 40 MPa, and can be polished as a finished surface. Choose this over SL400 when you need outdoor use, thicker pours, or a decorative polished floor. |

Common Questions
What is the difference between SL400 and SLE 500? — SL400 is the budget-friendly internal leveller (1-40mm). SLE 500 is the premium upgrade — it works internally and externally, pours up to 50mm, cures to 40 MPa, and can be polished as a finished surface. For standard internal jobs, SL400 is all you need.
Can I use SL400 outdoors? — No, SL400 is for internal use only. Use SLE 500 for external applications.
When should I use SLE500 FLEX instead of SLE 500? — Use SLE500 FLEX specifically when levelling over timber, particle board, or plywood subfloors. Its flexible formulation accommodates timber movement without cracking. SLE 500 is for rigid substrates like concrete.
What does KeraStik 3-in-1 replace? — It replaces three separate products: a flooring adhesive, a moisture control membrane, and an acoustic underlay. One product, one application, three functions.
Is WPM Plus compliant for wet area waterproofing? — Yes, WPM Plus complies with AS3740 (via AS/NZ 4858 and AS/NZ 4654.2) and comes with a 10-year BuildGreen guarantee.
