Primers (Adhesion Promoting)
PR-1 is a water-based resin used in conjunction with ADV Leather Cleaner or denatured alcohol to ensure adhesion on leather surfaces prior to repairs or color application. PR-1 is appropriate for all types of leather, including problematic leathers such as nitrocellulose finished, pull-up, oil-tanned, or pH damaged. Another attribute of PR-1 is it provides hold-out when finishing open-pored leathers, such as full- or semi-aniline, to retain softness and break characteristics. It can also be used on finished leathers, to promote adhesion on leather surfaces exhibiting signs of poor adhesion such as peel-up or flaking, or leathers that fail adhesion tests prior to repair compound or finish application. It is supplied in concentrate form, and should be mixed at a 1:3 ratio with ADV Leather Cleaner or denatured alcohol, although higher concentrations of PR-1 can be used in mixtures using ADV Leather Cleaner. We recommend no higher than 1:2.
PR-2 is designed specifically for promoting adhesion on leather which already has a finish or surface coating on it. It is more effective bonding new finishes to existing finishes than PR-1, but should NOT be used on unfinished leather, or finished leather surfaces where the existing finish is moderately to severely compromised. If PR-2 is allowed to penetrate into the leather's inner fiber structure, it will stiffen almost all types of leather. PR-2 can be mixed with denatured alcohol or acetone, at a ratio of 1:3 resin to solvent.
SG-4 is an economical one-step cleaner, pH corrector, and primer for all types of leather surfaces that is supplied ready to use.
PR-1 pre-mix and SG-4 primers can be used when converting a nubuck leather to a finished leather, but neither product should be used on suede.
