Product Name: EARTHAID
EARTTHAID is designed as a water-repellent admixture for Tech-Dry earth render system or other polymer render systems. Earthaid contains reactive silane/siloxanes which can react with earth render ingredients to impart durable water resistance to the entile body of the earth render against weathering.
Earthaid is used as a water repellent admixture for the Tech-Dry earth render system or other polymer render systems. The resultant earth render exhibits good surface beading and low water absorption. Earthaid also provides early water repellency to prevent wash-down due to rain or dew contacting the render before cure. The final water penetration through the render is significantly reduced.
Earthaid is added at a concentration of up to 4% by weight to the earth render. The resultant earth render exhibits excellent surface beading (as shown in Figure 1) resulting in very low water absorption of the earth render. The water resistance is developed very quickly, preventing wash-down due to rain or dew contacting the render surface before cure. The water absorption through the render can be reduced by up to 95%.
As earth render varies, it is always recommended that a test must be carried out prior to application to find the suitability of this product for the purpose.

Earthaid is easy to use. The following instructions should be followed when Earthaid is used in a typical earth render system:
As products and the condition of use vary, it is always recommended that a pilot trial should be carried out prior to using Earthaid to determine the suitability of this product for the purpose.
Handling & Storage:
Earthaid is classified as a non-hazardous material according to the criteria of Worksafe Australia. However, as with all chemical products, good industrial hygiene procedures should be followed when using this product. The product should be stored in closed containers in a cool dry place away from any fire sources. The product has a shelf life of 12 months in a sealed container stored at a temperature below 25oC.
Earthaid is available in 5 and 20 litre plastic drums. Other size containers may be available on request.
