Prepare for installation by mixing the components: Pour the Hardener into the Resin and add the required amount of Portland cement if needed. Maintain a ratio of 1 part Hardener to 2 parts Resin by volume in a clean pail, adding approximately 1 kg of cement per 10 kg of mix as necessary. Thoroughly blend with a low-speed (300-600 rpm) drill and mixing paddle for 3 minutes, ensuring to scrape unmixed material from the sides and bottom of the container. Avoid introducing air into the mixture and do not prepare more material than can be used within the product’s pot life.
Before installation, remove any standing water using a vacuum or oil-free compressed air. ADONA FASTKRETE Epoxy Bonding Agent can be applied to damp or dry surfaces but not through standing water. Optimal installation conditions include avoiding high temperatures, windy environments, or direct sunlight to maximize open time.
Apply ADONA FASTKRETE Epoxy Bonding Agent using a brush, roller, spray, or squeegee. Immediately follow by installing repair materials or concrete mix into the wet bonding agent. Ensure the bonding agent does not dry or become tacky before installation of concrete or mortar. If it does, abrade the surface and apply a recoat. Do not exceed the amount of bonding agent that can be effectively covered by repair mortars or concrete mixes while it remains wet.
Ensure concrete is sound, clean, and free from contaminants that could compromise adhesion or performance. Concrete should be at least 28 days old or fully cured to its designed strength. Use methods such as chipping hammer, water jetting, or mechanical means to remove loose or deteriorated concrete, achieving an open pore structure and a solid surface. Clear away debris with a vacuum or by blowing with high-pressure, oil-free air.
Remove rust and scale using a wire brush, sandpaper, or shot blasting for optimal results. Clean all dirt, grease, and old paint thoroughly. A clean, dry, and roughened, oil-free surface is essential for effective application.
Allow concrete to cure fully (28 days @ 70°F) before applying. Remove curing membranes by sanding or etching with a strong detergent.
Clean thoroughly with a grease-cutting detergent to remove oils and grease. Eliminate loose or unsound concrete using methods such as chipping, scarifying, shot blasting, sanding, or grinding. Proceed as with new poured concrete.
Strip peeling or degraded paint using sanding or a paint stripper. For intact paint, clean with a strong detergent and lightly sand to remove gloss. Treat any exposed concrete areas as bare concrete for further treatment.
