Description
Düfa Allgrund in white is an adhesion primer, rust protection and undercoat based on alkyd resin for metal, wood and rigid PVC indoors and outdoors. Rust-inhibiting pigments protect iron and steel against corrosion, while the Allgrund also promotes adhesion on zinc, aluminium, copper and many paint-compatible plastics. The 2.5 l tin has a matt finish, is ready to use and is the right size for gates, railings, fences and larger metal surfaces.
Advantages at a glance
- Three functions in one coat: adhesion promoter, rust protection and undercoat save a complete work step.
- Wide substrate range: iron, steel, zinc, aluminium, copper, rigid PVC and wood using the same procedure.
- Economical: approx. 80 to 100 ml/m² per coat, one tin covers around 25 to 31 m².
- Quick build-up: surface-dry after approximately 1 hour, recoatable after around 8 hours.
- For large areas: apply undiluted by brush, roller or airless sprayer.
Areas of application
- Corrosion protection on iron and steel, indoors and outdoors
- Adhesion primer on galvanised components, aluminium and copper
- Undercoat beneath solvent-based synthetic resin paints
- Gates, fences, railings, steel door frames and structural steelwork
- Rigid PVC and paint-compatible plastics
- Dimensionally stable and non-dimensionally stable timber components
Limitations & notes
Do not apply over rust, mill scale or forge scale: remove these layers down to bright metal first, otherwise corrosion will undermine the coating. Zinc requires an ammoniacal wetting-agent wash and at least two coats. Pressure-treated wood should not be coated until approximately six months of weathering. Excessively thick coats may wrinkle. Outdoors, two coats are always required.
Hazard statements: Warning. H226 Flammable liquid and vapour. H412 Harmful to aquatic life with long lasting effects. EUH066 Repeated exposure may cause skin dryness or cracking. Safety data sheet available from the manufacturer.
Application & tips
Prepare the substrate clean, dry, free of grease and dust; sand and degrease sound old coatings, remove unsound ones. Stir well and apply undiluted with a varnish brush, roller or airless sprayer; object and surroundings at least +5 °C, including during drying. Indoors one to two coats are sufficient depending on substrate, outdoors two coats are mandatory. Solvent-based, flammable: use only with good ventilation, away from ignition sources; wear safety goggles and solvent-resistant gloves (nitrile). When spraying indoors also wear respiratory protection with A2 gas filter. Clean tools immediately after use with cellulose thinner or brush cleaner. Store dry, cool and frost-free, seal opened containers tightly.
