JOINT COVERS, PROFILES FOR JOINTS AND ACCESSORIES SISTEMA BI FLEX PRODUCT DESCRIPTION BI FLEX is a combination of waterproof elements to treat joints and cracks. It consists of a TPE polymer- based ELASTIC TAPE and a two-component EPOXY ADHESIVE. PRODUCT APPLICATION • To apply a waterproof sealing on joints and cracks • To seal construction joints • Connect adjoining surfaces of joints, structures in general or prefabricated elements ADVANTAGES • Practical and simple application, it does not require expensive preparatory work • It can adapt to complex situations • 100% waterproof with positive/negative hydrostatic pressure • Control over hydraulic water-tightness, which is visible and repairable • Yellow to immediately identify the profile in case of maintenance following application and to avoid accidental breakage • High elongation capacity and absorption of dilatation • Excellent adhesion between tape and adhesive • Excellent adhesion on different substrates, such as concrete, mortar, stone, steel and galvanised steel • High resistance to chemical agents (conduct test) and thawing salts • Width specifically designed for casting (10 cm) or joint (20 cm) construction PREPARATION AND APPLICATION Preparing the surfaces Thoroughly clean the surfaces and remove any loose material with vigorous brushing, sanding or bushhammering. Grind or sand metal surfaces. High-pressure clean surfaces. For application with negative hydrostatic pressure the concrete surfaces must be roughened/milled for at least 2 mm and the water infiltrations must be removed using TAP 3/I-PLUG rapid-setting mortar. The surface must be dry. Mixing BI BOND epoxy adhesive Add all of the component B to component A. Mix for at least two minutes with an electric mixer until a smooth mixture with no colour streaks is obtained. Application of BI FLEX tape on cracks and movement joints On any cracks or movement joints, apply a normal adhesive tape, with a width of 20 mm, to the substrate.

JOINT COVERS, PROFILES FOR JOINTS AND ACCESSORIES The same adhesive tape must also be preventively applied along the mid-line of the BI FLEX tape. Apply a layer about 1-mm thick of the BI BOND adhesive in the same amount on both sides of the joint/crack and across a width at least 10 mm greater than the width of the BI FLEX tape. Immediately remove the adhesive tape and promptly proceed to install the BI FLEX tape, keeping the side with the previously applied adhesive tape towards you, mechanically pressing the BI FLEX surface to expel any air bubbles. Cover BI FLEX with an even layer of BI BOND...
