Self-Leveling Compounds: Latex vs Water-Based

Flooring TechDecember 1, 20236 min read

Choosing the Right Compound

Achieving a perfectly flat subfloor is essential before installing vinyl, tiles, or wood flooring. Self-leveling compounds (SLCs) are the solution, but which type should you use?

Latex-Modified Compounds

These are usually two-part systems consisting of a powder and a liquid latex additive.

Pros:

  • **Flexibility:** Excellent for substrates with slight movement, such as plywood overlays.
  • **Adhesion:** Bonds well to a variety of surfaces, including old adhesive residues.
  • **Speed:** Rapid setting times allow for foot traffic in as little as 2 hours.
  • Water-Based Compounds

    These are single-part protein-free powders that are mixed with water.

    Pros:

  • **Cost:** generally more economical than latex systems.
  • **Flow:** Excellent flow properties for a super-smooth finish.
  • **Pumpable:** Ideal for large commercial projects where pumping is required.
  • Conclusion

    For renovation projects involving timber substrates or adhesive residues, Latex is the winner. For new build concrete slabs where cost and speed of application over large areas are key, Water-Based systems are often preferred.
