Plastex can be used by sprinkling the powder onto repair or joint mating area and wetting with the Plastex liquid until the powder is saturated. Plastex can also be applied using the needle method. To use this method place a small amount of powder in the included plastic cup, place a small amount of Plastex liquid in the small applicator bottle and affix the needle. Place a drop of Plastex liquid on the powder and transfer to the repair area, repeating as necessary to fill the repair. Use the molding bar with one of the above techniques to fabricate missing sections. Use in a well ventilated area.
