Description

Crocodile Latex is water based non-ionically stabilized hydrolysis resistant dispersion of a carboxylated styrene-butadiene copolymer. Crocodile Latex free of APEO and therefore environmentally friendly. Crocodile Latex already contains antifoam to reduce air entrainment in cementitious systems. It is compatible with most hydraulic binders. In cement systems the use Crocodile Latex generally yields better workability, water resistance, Flexibility and chemical resistance. It is sued for modifying hydraulic binder systems in all common application in the construction industry, including industrial flooring, mortar, cementitious adhesive and slurry seals

Application

  • Surface Preparation: Remove all contamination, curing compounds, laitance and loose or unsound surface by mechanical means such as shot-or-sandblasting to provide a sound, rough texture substrate. Thoroughly wet the surface for several hours, then remove all excess water and allow surface to dry slightly until it appears darkened but no sheen is visible.

Mix Proportion:

Mix Crocodile Latex SBR latex thoroughly before using. Use 10 liters of Crocodile Latex per 50 kg of Portland cement. If a general purpose dilution of 2 parts of Crocodile Latex to 1 part water is reasonable choice.

Controlling the suction of high suction background

  • Apply Crocodile Latex diluted 1 part latex to 5 part water. At this dilution render coats can be applied to the dried or untried latex. (Damper the background with water is satisfactory if suction is only moderate.)

Bond coat for use over glass, glazed tiles, steel or dense concrete

  • Apply a generous brush coat of slurry consisting of 1 part of latex: 1.5 parts of Portland cement by volume. The render must be applied while this bond coat is still wet.

Bond coat for use over brickwork and block work

  • Control the suction as in system 1 and then trowel apply 3-5 mm thickness of a mix of 2 parts of Portland cement: 3 parts of sand by volume, gauged with 1: 1 dilution of Crocodile Latex: water. Key horizontally and allow to cure over night

In waterproof rendering over moderately strong background e.g… typical brickwork

  • System 1, followed by system 2. Cure overnight andapply a second slurry coat of latex / Portland cement. While this still wet apply a 7 mm. Coat of 1:4.5 cement: sand mix containing 10 liters of latex per 50 kg of cement, key horizontally. Next day apply a future 7 mm coat of same mix design.

In waterproof rendering over strong backgrounds e.g. dense concrete, and to reduce the rate of carbonation of the concrete

  • Apply system 2. While the slurry is still wet apply 1:3 cement: sand mix containing 14 liters of latex per 50 kg of cement, at 7 mm thickness. Key horizontal and next day apply a further 7 mm. coatof the same mix design

Caution

  • Paste 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
