What you need: fiberglass, anti-gravel, primer, varnish, paint, finishing putty, starting putty with fiberglass, Novol PLUS 720 polyester resin

The first step is to treat the corroded section of the threshold. To do this, we use a grinder with a petal circle and abrasive products. Then a hammer is taken into the hands, with its help the method of striking the worn-out metal increases the rigidity of the cleaned surface.

The fiberglass is cut into small strips to fit the size of the stripped hole with a margin. The metal freed from rust must be thoroughly lubricated with resin, after which the first piece of fiberglass is glued on top, which is impregnated with polyester. As soon as the materials "grab", another flap is applied and the whole procedure is repeated.

Having made a fiberglass casing, we polish it. The same grinder with a petal disc will help us in this matter. After removing all the differences, we apply a putty to the surface, wait for it to dry and process the place of repair with sandpaper, after which we apply the finishing putty. We take up the grinding again. Having achieved a flat surface, we apply anti-gravel to it.

After that, all that remains is to paint and apply varnish.
