Surface Preparation

For best results, all surfaces to be bonded must be clean, dry and free from dirt, dust, oil, loose paint, wax or grease, etc.


Directions For Use

1) For best results, the temperature of the adhesive and the surfaces being bonded should be between 60-80 degrees F.

2) Select spray pattern width by turning spray tip to desired setting.

3) Hold can 4-8 inches from surface to be sprayed and apply a uniform coat approximately 6 inches wide.

4) Apply 1-3 even coats.

5) Allow the adhesive to dry until tacky then apply sufficient pressure to ensure intimate contact.

NOTE: Test the tackiness by gently touching the adhesive with your knuckle. If the adhesive transfers to your skin, it is too wet. If the adhesive is aggressively tacky and does not transfer to your skin, it is ready to bond. If the adhesive only has a very light tack, it is too dry and another coat of adhesive should be applied to at least one of the surfaces.
