In case of renovation work, old sealant as well as old paint must be removed completely. It is recommended to apply a suitable back-up material (closed cell polyethylene backer rod or PE-foil) on the bottom of the joint to prevent the sticking of the sealant to the back of the joint. Instructions Sealant joint width should be designed to accommodate movement capability of sealant. Avoid application of the sealant during extreme temperature variations. Strict adherence to joint design process required (operational ability of DYNA-PRO® Acrylic can only be granted in case of correct processing as follows). Minimum joint width: 6mm. For joints 6-12mm wide, seal depth is 6mm. Above this range, apply width to depth ratio rule of 2:1 (12mm being the maximum). For joint dimensions greater than 25mm, please contact DYNA-PRO® Technical Service department. In situations where fillet joints are needed, a minimum of 6mm sealant bite to each substrate is recommended. Sealant may be tooled with water or a neutral non-dyeing tooling liquid. Priming Porous substrates, e.g. concrete and untreated wood should be pre-treated with a diluted sealant (DYNA-PRO® Acrylic with water in a ratio of 1:1 to 1:5). Before applying primer remove cement grouts, release agents and oil coatings. Bond beaker tape or backer rod should be used as back up material to provide back pressure and avoid three-sided adhesion that limits sealant movement capability. Shelf Life 16 months from date of production, when stored at or below 30°C in the original unopened container
