Description

Crocodile self-leveling is single component, high strength, non-shrink, fast setting, self-leveling underlayment that provides a flat, smooth, durable surface with minimum installation time and cost. Crocodile self-leveling uses a Portland cement polymer modified binder system, that when mixed only with water, poured or pumped (no trowelling needed) onto the floor, will level and smooth concrete and other subfloors prior to the installation of floor coverings. Crocodile self-leveling provides a superior bond to the substrate, can be applied up to 125 mm. (5 inch), and accepts foot traffic in 3-4 hours and floor coverage in 16 hours.

INSTALLATION
Applications require the use of Crocodile Primer prior to placement of Crocodile Self-leveling. Floor preparation is crucial in obtaining a successful underlayment installation. The contractor is responsible for ensuring the substrate is properly prepared prior to the application of Crocodile Self-Leveling. Do not apply over lightweight or gypsum base concrete.

CONCRETE FLOORS
Surface must be solid, completely clean, free of oil, wax, grease, sealers, curing compounds, asphalt, paint, dirt, loose surface material and any contaminate that will act as a bond breaker. Weak concrete surfaces must be cleaned down to solid sound concrete by mechanical means. Acid etching or chemical cleaning is not acceptable. Joints in the substrate must be reflected through the applied underlayment.

SUBSTRATE PRIMING
CONCRETE
All substrates must be clean, dry and primed before Crocodile Self-Leveling is applied. 1 Liter of Crocodile Primer mixed with 1 liter of clean potable water will cover approximately 8-10 m2 of floor area. Primer must be applied evenly with a nylon push broom with exploded tips. Do not use paint rollers, mops, or spray equipment. Apply a thin primer layer leaving no bare spots, puddles or excess primer. Allow to dry to a clear, thin film (usually 3 hours, but less than 24 hours). To avoid the development of bubbles and pin-holes in Crocodile Self-Leveling, very absorbent concrete, such as abrade floors, may require two application of Primer. Apply the first coat of Primer diluted with 3 parts water, let completely dry (minimum 3 hours) and install a second application of primer mixed 1:1 with water. Let dry the apply Crocodile Self-Leveling.

MIXING AND INSTALLATION
Mixed 2 bags of Crocodile Self-Leveling at a time. Mix Crocodile Self-Leveling 20 kg with water 4.8 liters. Then add the Crocodile Self-Leveling while mixing at full speed with a paddle mixer attached to a heavy-duty ” drill (min 650 rpm). Mix completely for a minimum of 2-3 minutes until lump free, adding no additional water. Crocodile Self-Leveling will level itself for 20 minutes at 21 ºC no troweling needed. Recommend to mix 2nd portion (of Crocodile Self-Leveling) immediately to apply continually. It can also be pumped affording high productivity and continuous smooth placement.

THICKNESS
Crocodile Self-Leveling can be applied from a feather edge to 40 mm. without extension with aggregate and up to 125 mm (5 inches) extended. Blend Crocodile Self-Leveling with washed, dried, clean 3-6 mm. pea gravel. Mix 20 kg of Crocodile Self-Leveling first with water, then add 6 kg of the aggregate mixing until the pea gravel is coated, then place. It may cause non-smooth surface ; recommend to apply pure Crocodile Self-Leveling with water on top. Allow the extended layer to dry, normally 16-18 hours. Prime the surface with Crocodile Primer mixed 1:1 with water per the priming instruction outlined. When this primer is completely dry, install the smooth un extended finish layer.

CURING
Crocodile Self-Leveling is self-curing. The application of concrete cures is not required. The surface is walkable in 3-4 hours after apply Crocodile Self-Leveling and can be overlaid any surface covering within 16 hours.

Precautions

  • For interior use only.
  • Do not install below 4°C or above 38°C
  • Do not install over gypsum based surfaces.
  • Do not over water, re temper, or add additional additives.
  • Reply upon floor covering manufacturer for directions concerning maximum allowable moisture content of subfloor, adhesivesselection etc.

Caution

  • Cement may cause injury to skin or eyes. Use of rubber gloves, dust masks, eye protection, and other safety equipment is recommended.
  • If contact with eyes occurs, flush immediately and repeatedly with water, and then contact doctor immediately.
  • Avoid contact with skin. Wash thoroughly after handling.
  • Keep out of reach of children
