Application Tips

• Surface to be filled should be clean and dry with no loose or powdery material.
• Exterior surfaces and metals (eg. nail heads) should be primed before application.
• Press filler firmly into cracks and holes and remove excess.
• Allow to dry (2-3 hours in thin 2-3mm applications depending on humidity). Allow longer drying times if painting with oil based paints (24 hours minimum) or for deeper applications.
• For deeper jobs apply in 10mm layers, allowing each layer to set before applying the next layer.
• Protect from rain until painted over.
• For best results, apply paint undercoat before applying water or oil based paint top coat.
• Use Poly Gap filler or silicone sealant where joint movement occurs.
• Clean up with water before filler dries.
• Cure product before disposal.
