PROPERTIES



Pourable, self levelling cement screed, for thicknesses of up to 10mm, that is fast setting and curing. It does not present any shrinkage cracks.
Distinguished for its high resistance to abrasion, compression, impacts and erosion.
Also distinguished for its strong adhesion to any mineral substrate, as well as its excellent rheology, workability and ability to be pumped.
Classified CT-C30-F6-AR6, per EN 13813.

APPLICATIONS



DUROSTICK D-65 is ideal for rapid levelling of concrete floors, cement screeds or existing mosaics to be coated with marble, tiles, vinyl flooring, carpet, hardwood flooring, pressed cement screed etc.
It yields a very smooth surface, which is able to remain as a finish surface for basement floors (pic.6), lofts, household storage rooms etc.

USE

1. Surface preparation:
Make sure substrates are stable, solid, without cracks, gaps and free from loose materials, dust, oil, and grease.
The substrate should be primed using DUROSTICK micromolar stabilizer AQUAFIX or the acrylic emulsion D-20, diluted with water, at a ratio of 1:1, before applying the product.
The consumption of D-20 is 1lt/5m2. Pour the product while the emulsion is still fresh.

2. Application:
Empty DUROSTICK D-65 into a clean container with cool water, at a ratio of 6-6.5lt of water to 25kg of powder, and mix with a low speed electric mixer, until a lump free, homogenous mass is created (pic.1). Allow the mixture to mature for 1-2 minutes and mix again. Starting from a corner (pic. 2), apply the product using a floor squeegee or a wide notched trowel, thus helping distribute the product evenly on the entire floor (pic. 3-4). Remove any air bubbles using a wide, stiff street broom (pic. 5), or a spiked floor roller.

NOTES

• Use DUROSTICK D-64 self levelling cement mortar, for applications that need thicknesses up to 30mm.
• Do not use the product when it begins to set. The mixture should not get remixed with additional water.
• Protect the finish surface from frost and high temperatures while soaking for the next 24 hours.
• The product, after hardening, is harmless to health and the environment.

Clean all tools and equipment with
water, immediately after use.
