Description
Sikadur®-31+ is a 2-part, low-VOC, moisture-tolerant epoxy adhesive designed for structural bonding and concrete repair applications. It offers excellent adhesion to a wide range of construction materials including concrete, natural stone, ceramics, fibre cement, mortar, brick masonry, steel, iron, and wood. The product is suitable for repairing structural and non-structural concrete elements, bonding reinforcement plates, increasing bearing capacity with mortar, and filling joints, cracks, holes, and voids. It is thixotropic, allowing non-sag application on vertical and overhead surfaces, and hardens without shrinkage. Sikadur®-31+ meets class R4 structural repair requirements according to EN 1504-3:2005, has good mechanical strength, abrasion and chemical resistance, and does not require a primer. Ideal for both DIY and professional projects, it can be applied up to 30 mm in a single layer and performs well on dry or mat damp concrete.
