Pro tips
For renovation projects in Belgium where ambient humidity can vary, ensure proper ventilation of rooms during and after application to promote uniform drying. The 20 kg format is ideal for professional plasterers working on multiple rooms: it minimises interruptions for restocking whilst remaining manageable. Remember to seal the bucket tightly after each use to preserve product quality and prevent surface crust formation.
FAQ
Can Expert'Ultim be used on all types of plasterboard?
Yes, this 3-in-1 filler is suitable for standard plasterboard, moisture-resistant and fire-resistant boards. Simply ensure the substrate is clean and fixing screws are slightly recessed below the surface.
How many coats are needed for optimal results?
For tape application, two coats are generally sufficient: one for embedding and one for finishing. For complete surface skimming, allow two to three thin coats depending on the initial condition of the substrate.
Can the filler be tinted before application?
Expert'Ultim is a preparation filler designed to be covered with paint or a finishing coat. It is not intended to be tinted. For a coloured finish, apply your chosen paint after the filler has completely dried.
What is the difference between this 3-in-1 filler and separate products?
Expert'Ultim offers a balanced formulation that meets the three main applications, simplifying logistics and reducing the number of products to stock. Professionals save time on site by using just one bucket for all finishing work.
