Product Information

Product Description

OPTI-MIX 3 in 1 RENDER ADDITIVE is a highly concentrated waterproofing, plasticizing and retarding admixture for sand and cement mixes which is 10 times the strength of conventional products.

OPTI-MIX 3 in 1 RENDER ADDITIVE provides long term protection from water damage to mortar, concrete, renders and screeds by reducing water permeability. The product also contains air entraining, plasticising agents hence it will not “deaden” the mix and there is no need to add a separate admix. The “retarding properties of 3 in 1 RENDER ADDITIVE provide longer “working times” of mortars where increased mixed sizes can be prepared.

Application

Shake bottle well before use. Push the lid downwards and twist anti-clockwise to remove. Squeeze the sides of the bottle to fill the measuring cup to the required dose (25-50ml per 25kg of cement).

Add OPTIMIX 3 in 1 RENDER ADDITIVE to a bucket of water and stir/mix well (use up to a maximum 10ltrs of water). then add to the empty mixer, followed by the sand and cement. Always ensure that minimal gauging water is used to the early stages of the mix and add water at the end, when all

materials have been added to achieve the required consistency. Do not use below 2 degrees C.
