The two render samples shown in the above picture are made from exactly the same render from the same bag. The sample on the right was simply scraped much earlier during the drying process than the render sample on the left and the difference that can make on the outcome of the final colour of all cementitious renders can be quite profound. It is for this reason we strongly recommend that you request samples of Mendrend so you can test the colour before ordering any materials and it also helps us determine that when you receive any ordered materials that it is the correct colour as the render applied on-site cannot be used as an accurate colour gauge. We offer a full colour matching service, either on-site or to customer provided samples to get around this issue.
It is very common for applicators to scrape renders early, therefore the colours achieved on site could possibly be much stronger than the colours of manufacturer provided samples which are made in a laboratory under ideal circumstances. It should be noted that all manufacturers of cementitious render products would deem this to be normal behaviour of the product.
