Colouring Cement with Sika Additive
Posted by armeet on January 23, 2007
I have been advised on a 3:1 sand/cement mix with Sika 1 additive to waterproof my shower enclosure. However, I would like the finish screed to be white in colour. If I add colourant to the mix, will it affect the chemical composition of the screed? Thankyou
Sika 1 is an integral waterproofing admixture in Sika’s European product range, I am in Sika US and we do not have this product here. But reading the technical data sheet of the product I do not think adding any color additive in the cement mortar screed is going to have a negative influence on it. But if you are looking for a white colored mortar screed, you will have to use a white cement in the screed instead of grey cement or adding any color additive.
Another alternative would be to use pre-packed water-proofing mortars available in the market specifically made for such applications. These finished products could be purchased in white or grey color.
