Before application, ensure the designated area is completely dry and in a stable and sound condition. The surface should be cleared of any substances that might obstruct adhesion, such as dust, oils, and grease. Remove all laitance (a weak, milky layer of cement and fine particles) and any surface treatments previously applied. To improve adhesion, mechanically roughen the surface to create a better grip for the primer. Ensure all surfaces are dust-free and meticulously clean prior to the primer's application. If underfloor heating is present, it must be turned off at least 48 hours before and after the primer is applied.
When using Ultra Tile Pro Primer on a calcium sulphate screed, additional preparation steps are necessary. It's crucial to ensure that calcium sulphate screeds are dry and have a relative humidity (RH) below 75%. These types of screeds are susceptible to surface laitance, which must be mechanically abraded to eliminate this fragile layer, in addition to the general preparation steps outlined above.
