Nov 1, 2026

Uploaded by Dusta123

ARDEX TL 1000 is a self-leveling underlayment formulated from Portland cement, hydraulic cements, and polymers for fast interior floor leveling before installing tile or stone. It delivers a durable, smooth, flat surface with minimal labor and can be poured or pumped when mixed with water. Suitable substrates include properly prepared interior concrete, cementitious terrazzo, and ceramic, quarry, or porcelain tile surfaces, provided they are clean, sound, dry, and correctly primed. Installation guidance covers substrate prep, handling curing-compound-treated concrete, tool recommendations, deep vacuuming, and strict joint/crack limitations.

ARDEX TL 1000 is designed specifically for fast leveling of interior concrete, cementitious terrazzo or ceramic, quarry or porcelain tiles prior to installing flooring – on, above or below grade. It can even be installed over concrete treated with certain curing compounds (see below) . Pourable or pumpable when mixed with water, ARDEX TL 1000 seeks its own level and produces a durable, smooth and flat floor surface with minimum labor. Substrate Preparation (Proper Prep™) Concrete All concrete substrates must be solid, structurally sound, thoroughly clean and free of oil, wax, grease, asphalt, latex and gypsum compounds, sealers, certain curing compounds** and any contaminant that might act as a bond breaker. If necessary, mechanically clean down to sound, solid concrete by shot blasting or similar. Overwatered, frozen or otherwise weak concrete surfaces must also be cleaned down to sound, solid concrete by mechanical methods. Acid etching, adhesive removers, solvents and sweeping compounds are not acceptable means of cleaning the substrate. Sanding is not an effective method to remove contaminants from concrete. Substrates must be dry and properly primed for a successful installation. Substrate and air temperatures must be a minimum of 50°F (10°C) for the installation of ARDEX products. For further information, please refer to the ARDEX Substrate Preparation Brochure. **Concrete Treated with Curing Compounds Test areas of ARDEX TL 1000 can be installed and evaluated over concrete slabs that have been treated with either silicate or acrylic resin curing compounds. These compounds must be installed in strict accordance with the compound manufacturer’s written recommendations. If a silicate type has been used, all residual salts must be removed. For instructions on priming concrete with acceptable curing compounds, please refer to the Priming section of this technical data sheet. Please be advised, however, that there are a number of curing compounds sold today that are wax- or petroleumbased emulsions. These are permanent bond breakers that must be removed completely prior to patching or leveling. Dissipating compounds must also be removed completely by mechanical means prior to installing any ARDEX material. It is imperative to be able to determine the type of curing compound that was used before proceeding. Any curing compound that cannot be identified should be completely, mechanically removed. Cementitious Terrazzo or Ceramic, Quarry or Porcelain Tiles ARDEX TL 1000 can also be applied over clean, sound and solidly bonded cementitious terrazzo or ceramic, quarry or porcelain tiles. The substrate must be clean, includingthe complete removal of existing sealers, dust, dirt, debris and any other contaminant that may act as a bond breaker. Where necessary, substrate preparation must be by mechanical means, such as shot blasting. Note on Asbestos-Containing Materials Please note that when removing existing flooring, any asbestos-contai

FAQs

What is ARDEX TL 1000 and what is it used for?

ARDEX TL 1000 is a self-leveling underlayment designed for fast leveling of interior concrete, cementitious terrazzo, and ceramic/quarry/porcelain tile substrates before installing flooring. It produces a durable, smooth, and flat surface with minimal labor.

How should the substrate be prepared before installing ARDEX TL 1000?

Concrete substrates must be solid, structurally sound, thoroughly clean, and free of bond breakers such as oil, wax, grease, asphalt, sealers, and certain curing compounds. Mechanically clean if needed, ensure the substrate is dry, and properly prime for the installation.

Can ARDEX TL 1000 be installed over moving joints or moving cracks?

No. ARDEX TL 1000 should not be installed over any moving joints or moving cracks. Existing expansion, isolation, and construction joints, as well as all moving cracks, must be honored through the underlayment and flooring.
