Kerakoll Kerarep Crack Repair Adhesive

Description

Kerakoll Kerarep Crack Repair Adhesive is an extra fast-acting, bonding agent for gaps and cracks. Kerarep develops a high level of adhesion and fluidity thereby guaranteeing the monolithic continuity and total filling even of millimetric gaps and cracks in damaged structures, before laying the covering.

Key Features:

• High degree of slide even on dry, absorbent structures
• Suitable to bond metal or as a binder in mortars for small repairs

Areas of application:

Kerakoll Kerarep Crack Repair Adhesive is for ultra rapid sealing of:
– damaged, cement-based screeds
– damaged parts of concrete structures

Anchoring of:
– strips, profile sections and joints

Preparation of:
– high-performance, high adhesion mortars for small repairs to corners, edges and patch layers in screeds and concrete structures (mixed with dry sand)

For internal and external use on cement-based screeds, concrete structures, reinforced concrete and metal.

Instructions for use:

Preparation of substrates:
Widen the cracks and make cuts across the same crack with a cutting disc every 15 – 30 cm so that the casting compound can penetrate for at least 2/3 of the thickness of the screed. Vacuum and insert the staples for the screed. Metal parts or elements must be free of rust and grease. For small patch layers, the substrate must be solid (i.e. free from any parting compounds and loose or easily removable parts) and clean, dry, roughened and when possible, also sanded. Apply Kerakoll Kerarep on dry substrates.

Preparation:
Prepare Kerakoll Kerarep quickly, either by hand or with a mechanical low-rev agitator; mix component A with component B (preset ratio 1,000 : 30 in the bags) until a fluid paste of uniform colour is obtained. Workability times may vary quite considerably, according to the quantity of mixed paste and the temperature of the environment, the sealant and the substrate: at high temperatures and with high quantities of mixed paste, workability times will be shorter. At lower temperatures and with small quantities of mixed paste, workability times will be longer. Low temperatures can also make the resin less fluid. When preparing mortars, after mixing Kerakoll Kerarep part A with part B, add dry sand in a ratio of ≈ 1:1 by volume, then mix until fully integrated.

Application:
Kerakoll Kerarep, fluid with low viscosity, is applied in a single solution for pouring in gaps, cracks, and holes in concrete or screed. Press down with a metal trowel to facilitate penetration and add resin as necessary until the space is filled completely. Broadcast sand on any remaining residues before Kerakoll Kerarep hardens. Excess sand must be completely removed before any subsequent applications.
