FAQs.

1: What types of projects is LX-40 best suited for?

LX-40 is ideal for standard levelling applications from 2-12mm where you need a reliable, cost-effective solution. It’s perfect for preparing concrete floors, cement:sand screeds, and sound tile adhesive residues prior to laying ceramic tiles or soft floor coverings. If you’re working on smaller residential projects with relatively flat floors that just need a smooth finish, LX-40 offers the right balance of performance and value.

2: How does LX-40 compare to other Dunlop levellers?

  • LX-40: Standard leveller for straightforward applications up to 12mm deep
  • LX-200: Mid-range flexible option for surfaces with slight movement (0-20mm)
  • LX-360: Deep fill fibre-reinforced option for significant depths or movement (3-60mm)

All three share the same 25 N/mm² compressive strength, 4 hour tiling time and 24 hour resilient flooring readiness.

3: How much LX-40 will I need for my project?

  • One 20kg bag covers approximately 4m² at 3mm thickness
  • Coverage formula: 1.6kg per mm per m²
  • Example: For 10m² area at 3mm depth = 5 bags (1.6 × 3 × 10 ÷ 20 = 2.4 bags, rounded up)

Remember to factor in an extra 10% for wastage and uneven surfaces.

4: How soon can I tile or apply floor coverings after using LX-40?

  • Walkable: 4 hours
  • Ready for ceramic tiles: 4 hours
  • Ready for resilient flooring (vinyl, LVT, carpet): 24 hours

This quick-setting formula helps keep your project moving without unnecessary delays.

5: What preparation is needed before applying LX-40?

  • Clean, dry, and dust-free surface
  • For porous surfaces (concrete/screed): Prime with Dunlop Multi-Purpose Primer diluted 1:1 with water
  • Mix ratio: 20kg bag with approximately 3.8 litres of water
  • Allow mixed product to stand for 2 minutes, then remix before application

Proper preparation ensures maximum bond strength and a professional finish.
