Yes, it adheres well to metal, provided the surface is clean, rust-free, and scuffed to improve mechanical bonding.
Curing time varies based on ambient temperature, but generally, it is ready for sanding within 20 to 30 minutes.
Once fully cured and finished with a topcoat or paint, the repair becomes water-resistant and suitable for outdoor use.
Yes, this product typically requires a separate hardener to initiate the chemical reaction necessary for curing.
It is recommended to apply a primer layer over the sanded filler before applying your final topcoat to ensure color uniformity and adhesion.
Ensure the correct ratio of hardener was used and that the two components were thoroughly mixed until a uniform color was achieved.
The surface was likely not cleaned or scuffed enough before application; ensure the substrate is clean and prepped for mechanical adhesion.
Apply the paste using a firm pressing motion with the spreader to force air out of the defect, or perform a second thin fill layer.
Before starting your repair, ensure the substrate is clean, dry, and degreased. If you are working on metal, scuff the surface with abrasive paper to improve adhesion. For GRP, ensure no wax or residue is present. Always mix the paste with its hardener precisely according to the ratio indicated on the packaging to prevent soft spots. Store the container in a cool, dry place and ensure the lid or bag is sealed tightly after every use to prevent the paste from drying out prematurely. Keep the product away from direct sunlight during storage.
