Setup, Compatibility & Care
To prepare the filler, combine approximately 2.5 parts powder to 1 part clean, cold water in a clean vessel. Mix until you reach a smooth, stiff consistency. Use the product within 40 minutes of mixing; using a dirty container can significantly alter the setting time. For highly absorbent surfaces, lightly dampen the substrate with water before application.
When working outdoors, ensure the weather is dry, as rain will ruin the setting process. Once the filler has completely dried, protect the area from weathering by applying a coat of oil-based paint or varnish. Always clean tools and mixing vessels with warm water immediately after use, before the material hardens. Store the unused powder in a cool, dry place to maintain its shelf life.
