Pretreatment
The surfaces to be bonded must be clean, free from oils, grease, dust and loose particles. Pooled water should be removed. Check paint or coatings are firmly attached, if not remove it. In cases of unknown materials or critical applications adhesion pre-tests are recommended.
Application
1) Cut off tip of the cartridge above the screw thread. 2) Screw on plastic nozzle and cut off the tip of the nozzle. 3) Place cartridge into gun. Because of the very high tack formula, the product has a high resistance to extrude. Therefore cut nozzle sufficient (min. 8mm diameter) or in a V-shape. Apply adhesive onto the surface of one of the elements to be bonded: In spots (1) in order to smooth uneven surfaces, in wave-like form (2) for higher initial tack with large surfaces or in straight beads for smaller surfaces (3). In case of outdoor use, apply vertical strands.Release gun after appliance to stop adhesive flow. (not valid for Foldable Gun (DW111/120). Firmly fix items to be bonded into position with a twisting action. If necessary (e.g. heavy items and items under tension), support the items until cured. Items can be adjusted after application. Minimum thickness of the adhesive layer should be 1 mm to ensure ventilation.
Important in case of 2 non-absorbent surfaces: Adhesive must not form continuous areas as contact with air/moisture is necessary for adhesive setting. Make sure the adhesive beads do not merge.
For filling applications
Maximum joint width: 20mm. Firmly extrude UniBond No More Nails All Materials Heavy Objects into the gap and make sure that it is a full contact with the sides of the gap. Fill the gap and avoid air entrapment. Product should be tooled firmly against the gap sides to ensure good adhesion.
Cleaning
Clean tools and application equipment immediately using white spirit or ethanol. Cured product can only be removed mechanically (e.g. with a knife or a scraper).
