You know how crucial a perfect base is. With Sikafloor®-132 Level Rapid, we’re here to help you achieve exactly that, fast-setting, smooth, level, and ready for whatever comes next. Follow this step-by-step guide to get the best results every time.

1. Get Your Substrate in Top Shape

Before you open that bag, prep is everything.

Check Your Concrete or Screed:

  • Must be at least 28 days old.
  • Surface should be dry, clean, sound, and free from any debris.
  • There must be a working damp proof membrane.

 

Remove Any:

  • Old adhesive residues
  • Oil, grease, wax, dust
  • Loose paint or flaky surface layers
  • Laitance or anything that could mess with adhesion

2. Prime

For Porous Surfaces (like typical concrete or screed):

      • Prime with SikaBond® PVA+.
      • Mix 1 part PVA to 4 parts clean water.
      • Apply a generous, even coat and let it dry completely.
      • On highly porous areas, consider a second coat to avoid pinholes or debonding.

       

              For Non-Porous Surfaces (tiles, terrazzo, dense concrete):

                  • Mechanically roughen the surface, grinding or scarifying is the way.
                  • You’re aiming for a mechanical key for the product to grip
                  3. Mixing

                  What You’ll Need:

                  • Clean mixing container
                  • Mechanical mixer with a spiral paddle
                  • Clean, cold water

                   

                  Mix Ratio:

                  • 16 kg powder needs 2.6–2.8 litres of water
                  • Always add powder to water (never the other way around)

                   

                  Mixing Method:

                  • Mix at medium speed until you get a smooth, lump-free consistency
                  • Once it starts to stiffen, don’t remix or add water
                  • Working time: around 5–10 minutes at +20 °C
                  4. Application
                  • Floor temperature must be 5 °C or above
                  • Turn underfloor heating OFF 48 hours before, and keep it off for 48
                    hours after


                  Pro Tips:

                  • Best applied at 2–10 mm thickness
                  • On large areas, work in pairs—one mixing, one applying—to stay on
                    those wet edges
                  • Pour the mix on the primed surface, and spread with a steel trowel
                  • Add more product while it’s still wet to build thickness as needed
                  • The self-smoothing formula will help trowel marks disappear
                  • Use a spiked roller (within working time) to remove air bubbles and
                    enhance finish
                  5. Curing
                   
                  • Keep the area free from drafts and direct sunlight during curing
                      • Premature drying = surface defects, and we don’t want that

                      6. Clean Up
                      • Clean all tools and equipment immediately with water
                      • Once it sets, it’s not coming off easily, so act fast

                      Pro Checklist Before You Start:

                      • Substrate clean, dry, and primed?
                      • Mixing gear ready?
                      • Temperature okay? Heating off?
                      • Working in a team on a big area?
                      • Know your working time? (~10 mins tops)
