Ten tips for a successful end result

Spray filling is suitable for large surfaces. Roller filling is best for medium-sized surfaces. Hand filling is most appropriate for small surfaces. Choose the filler based on method and substrate.

Demand that the “builder” hands over surfaces that are ready to decorate, i.e. that all concrete must be completed and cleared, and plasterboard must be fitted in accordance with instructions. Make sure that the substrate is firm, clean (free of grease and dust) and dry. Document any deviations.

Take care to always use the right tool. This makes work easier and guarantees a good end result.

Never work at temperatures below +10°C. The optimal temperature is +15°C to +20°C and 40–60% humidity. Never apply filler on damp substrates, as there is a negative impact on adhesion and it can result in variations in the gloss of the surface treatment.

Remember to use protective gloves, eye protection, respiratory protection, hearing protection and protective paper.

If both ceiling and walls are to be filled, start with the ceiling. It is best to work from the light source and into the room.

Filler dries slowly if it is applied too thickly. Several thin layers always produce a better result.

Keep in mind that whatever you apply has to be sanded. The more effort you put into applying the filler, the less work is needed for sanding.

Avoid sandpaper that is too coarse-grained. Remove sanding dust before you apply the next layer. Otherwise adhesion is compromised.

Always follow the manufacturer’s instructions. Most manufacturers have comprehensive product information available on the Internet. If not: request product information from your supplier.
