One of the most common issues we receive here at ARDEX is the overwatering of materials.
When mixing, specific products need the exact amount of water as per the datasheets, to get the full performance out of the product.
Once you add too much water, you are potentially ruining the performance. Yes, you may make it more workable and get more coverage, however the performance of the product is now compromised and the potential for failure of that product may occur.
For more information on mixing ratios and water content, please contact ARDEX technical services on 1800 224 070.
