BondCrete contains an exclusive resin additive ensuring maximum bonding strength. BondCrete is suitable for Tiling, adhesive for craft work, patching of most surfaces, sealing concrete, rendering surfaces and most cement applications. BondCrete is widely used in the building and renovating industry.
bondcrete as an admix: bondcrete 1 part water 10 parts is an ideal admix ratio for cement toppings, concrete, plasters etc. For estimating purposes 2 litres of bondcrete diluted with 20 litres of water is normally sufficient for mixing each 40 kg bag of cement.
A bonding agent (bonding adhesive) needs to be painted onto the existing concrete first to ensure that the fresh concrete will successfully adhere. This is also true of floor repairs, if concrete is used to fill gaps caused by damage. The new won't adhere to the old without the help of a bonding adhesive.
* PRIMING AND SEALING PRIOR TO PAINTING: One sealing coat of diluted BondCrete (BondCrete1: water 4) will provide an excellent sealer or key when applied to new or old cement rendered walls, plaster etc.
Concrete Primer/Sealer
One sealing coat of diluted Bondall BondCrete (BondCrete 1:Water 4) will provide an excellent sealer or key when applied to new or old cement rendered walls, plaster, etc.
Eppoxy glue is great for concrete projects! But you can also use epoxies for other repair and construction jobs.
You can put new concrete over old concrete. However, unresolved issues with your old concrete, such as cracks or frost heaves, will carry over to your new concrete if not taken care of. In addition, you must pour it at least 2 inches thick.
Epoxy Resin
Epoxy resins are widely used in the construction field because of their high compressive strength, strong adhesion, chemical resistance and other unique properties. They are available for the bonding of fresh concrete to the old concrete.
The most effective way to ensure a really good bond is with a scratch coat. This is simply a very wet coat made up by mixing the repair product with water. Mix up a small amount of the repair material to a soupy consistency. You don't need to measure the water—just turn the stuff into slop.
When a concrete mixture is too wet, it causes a greater amount of shrinkage during the drying process than is needed. As a result, the concrete has a great likelihood of cracking and for those cracks are likely to be a fairly good size.
Kookaburra Paints PVA Adhesive & Cement Mix 20L (Bondcrete equivalent) Versatile bonding and sealing agent. Exclusive resin additive ensuring maximum bonding strength. No need to hack, chip or acid etch most surfaces before bonding.
To make the concrete stronger, add more cement or less sand. The closer you bring the ratio to an even one-to-one of sand to cement, the stronger the rating becomes. This principles works in the opposite direction as well.
Liquid detergent acts as an air-entraining admixture. During mixing, the detergent forms tiny air bubbles that are distributed throughout the mortar. These air bubbles lubricate the mortar, making it workable for long periods, even as the water evaporates.
In instances where concrete is placed against a hardened concrete, the two can become bonded to each other. Often a cement paste is applied to wet the hardened material, improving the chemical interaction at the surface. Bonding agents are also available to assure bond between distinct concrete surfaces.
LIQUID NAILS® Concrete & Mortar Repair, (CR-805), is a weather-resistant indoor/outdoor acrylic compound with silicone, ideal for repairing and sealing cracks and joints in concrete and masonry surfaces. This easy-gunning sealant dries gray similar to concrete or can be painted.
PVA Bonding Agent imparts excellent adhesion to cement and concrete; It allows a strong bond to be formed between cement and a variety of substrates and imparts excellent adhesion to concrete, enabling easy repair of concrete surface without the need for mechanical preparation of the surfaces.
GorillaWeld is an incredibly strong and heavy duty steel bond epoxy. The formula has a 4250 PSI bond strength and sets in just 10 minutes. GorillaWeld is also waterproof and versatile, creating a long lasting, permanent bond to: metal, plastics*, concrete, ceramics, PVC, fiberglass and more!
Epoxy is the most cost-effective of these floor coatings and is thicker than acrylic, providing more protection for your floor.
Concrete should be sealed to protect from mold and mildew.
Because concrete is a porous material, it has a tendency to absorb moisture. When this moisture doesn't dry and the surface is left wet for an extended period of time, mildew begins to form and mold begins to grow.
