Application advice
For mechanical Airless application, use a pump with a minimum capacity of 5 litres per minute, fitted with a nozzle 531 to 539. Maintain a distance of 60 to 80 cm between the gun and the substrate to achieve an even coat. The filler can also be applied with a roller, joint machine or manually, depending on your preference and the scale of the project.
Its excellent slip makes work easier and its strong filling power reduces rework, speeding up the work pace on site. The long working time allows you to work without rushing, whilst sanding is straightforward for a perfectly smooth surface. Once dry, the filler accepts all types of finishes: finishing plasters, paints or wall coverings.
Ensure that substrates are clean, dry and dust-free before application. For large areas or renovation projects, Airless application optimises your productivity whilst guaranteeing consistent finish quality.

Pro tips
For professionals working with airless, the Semin 3 EN 1 - GLJ offers genuine versatility that simplifies site logistics. Rather than managing multiple buckets for filling, smoothing and taping, you have a single product. Remember to thoroughly mix the filler before use and clean your equipment with water immediately after application. On Belgian job sites where humidity can vary, pay particular attention to drying times: in humid weather or in basements, allow around 12 hours. Its A+ rating makes it an ideal choice for renovations where occupants remain on site.
