Application Information
Instructions for use


Cut Vetoflex PBR according to the required length and lay it along the joints accordingly. Next, gently push the cord against the joint with extra caution not to damage the skin of the material.

Ensure that the diameter of Vetoflex PBR is approximately 20% to 25% (required depth to width ratio) greater than the joint's width to ensure that the cord is tightly held in position. This procedure further enhances the aesthetic effect of the material when done on a firm base. Next, seal the joint with a suitable sealant from Saveto’s product range.

Surface Preparation

All surfaces where the backing rod is to be inserted must be dry, smooth, clean, free from dust, laitance, or loose materials. When otherwise necessary, it is highly recommended to use compressed air or a wire brush in order to remove further dirt, oil stains, and other inconsistencies.
