Conmix Latex is an aqueous emulsion especially formulated for use with cementitious mixes. It is used in mortar and concrete to improve the waterproofing, wear resistance, durability and bonding properties. Mortars containing Conmix Latex may be used for vertical, horizontal and overhead repair work.
Conmix Latex is used to substantially improve the qualities of cement mixes, for example: thin layer patch mortars, renders, floor screeds, concrete repair mortar, abrasion resistant linings, fixing mortars, bonding slurry etc.

Advangtages include
- Excellent water resistance.
- Increased durability.
- Plasticising effect and reduces shrinkage.
- Improved corrosion protection.
- Economical.
- Higher flexibility.
- Good resistance to many salts and chemicals.
- Excellent adhesion to concrete, mortar, stonework, plaster & blockboard.
- Thermal expansion and elastic modulus similar to concrete.
- Non toxic.
- Improves cohesion & workability.
- Single component easily gauged.
- Improved flexural & tensile properties allow for thin application.

The below results are approximated and achieved by considering the properties of a sand : cement mortar at 3 : 1 combined with Conmix Latex at 10 litres per 50 kg. of cement.

Conmix Latex mortars, toppings and renders must be well-compacted on to the primed substrate by trowel. Exposed steel reinforcement should be completely encapsulated by the mortar. Conmix Latex mortars can be applied at a minimum thickness of 6 mm. and up to 40 mm. thickness, dependent on the location and configuration of the repair zone. Where thick sections up to a total thickness of 40 mm. are to be built up by hand or trowel application, the surface of the intermediate layers should be scratch-keyed. Application of the slurry primer and a further application Conmix Latex mortar may proceed as soon as this layer has set.

SUBSTRATE PRIMING
The substrate should be thoroughly soaked with clean water and any excess removed prior to commencement. A slurry primer should be prepared consisting of 1 volume Conmix Latex to 1 volume clean water to 1-3 volumes fresh cement. The slurry should be stirred frequently during use to offset settlement & worked well into the surface. Avoid ponding. The repair mortar, topping or render must be applied on the wet slurry primer. If the slurry primer dries before application of the mortar, it must be removed and the area reprimed before continuing.

METHOD OF USE
In all situations the surface must be in a clean, laitance free and roughened state. Absorbent surfaces should be saturated thoroughly with water, but avoid ponding. Oil or grease deposits should be cleaned away. Pull off tests should be conducted to assess decontamination. Expose rebar & clean to bright condition. Grit or sand blast. Remove any corrosive agents such as chloride by high pressure water blasting.

SUBSEQUENT FINISHES
Conmix Latex can be finished with a steel, plastic or wood float, or by a damp sponge technique, to achieve the desired surface texture. The completed surface should not be overworked.

HEALTH & SAFETY

Wear suitable protective clothing, gloves and eye protection. The use of barrier creams provide additional skin protection. In case of contact with skin, rinse with plenty of clean water, then cleanse with soap and water. If poisoning occurs, contact a doctor or Poisons Information Centre. If swallowed, DO NOT induce vomiting - give a glass of water. If in eyes, hold eyes open, flush with water for at least 15 minutes and see a doctor. If skin contact occurs, remove contaminated clothing and wash skin thoroughly with soap and water.
