Surface preparation is absolutely vital to ensure that the bonding agent is applied to a sound concrete surface. This involves intensive cleaning, usually by pressure washing you may also want to consider our Decap Roc floor cleaning solvent , or vacuum shot blasting. Rocland offers three different bonding agents.
The choice depends on where the bonding agent will be used, and the likely use of the final floor surface. The bonding agents should be carefully and thoroughly applied, either with a brush, a broom or a roller — or for larger areas they can be sprayed on. Concrete glue comes stored in two formats: tubs that require mixing and must be applied to both surfaces, and cartridges for use with a caulking gun.
If your project requires smaller repairs or amounts of glue, opt for the caulking technique. All you have to do is prep the space, add the cartridge to the caulking gun, and run the applicator around the perimeter of one object. Press the pieces together and follow the instructions as to how long the concrete glue will need to cure. This will provide a strong, rigid bond via pre-filled syringes of the construction glue. Choosing a concrete adhesive means knowing the size and scale of the job at hand.
It is available in a pre-mixed form or by buying the separate ingredients in bulk. If you haven't adhered concrete to concrete before, it is a good idea to go with the pre-mixed version, which only requires that you add water. Buying the raw materials, gravel, Portland cement and sand is considerably cheaper than buying pre-mixed concrete patching. If you are patching a deep hole, you can use 1-inch 2.
Mix the dry materials in a ratio of 3 parts gravel to 2 parts sand to 1. This is sometimes listed as 3 to 2 to 1. A higher amount of cement will create a stronger material. There will be more of chemical reaction between the cement and water, which will create more crystals and a harder structure.
Sweep the concrete surface carefully. You must remove all loose stones, or the bonding agent and cement will not reach the surface of the concrete. Dust the surface thoroughly after you have swept. You can use a blower or a soft brush; wipe away the dirt that is stuck to the surface. Rinse the concrete. Sprinkle an even amount of water onto the surface with a hose attachment.
Stop adding water before you create standing water on the surface. Create cement paint. Mix Portland cement, which is available at most hardware stores, with water. Stir the 2 ingredients together until they form the consistency of wet paint. You can also buy an acrylic bonding agent to use in place of the homemade cement paint.
They are made of resin and can be either added to your patching concrete or applied like the cement paint. Follow the instructions on the can or bottle very carefully, as many of the products have different application instructions and drying times.
Apply a thin layer of the cement paint to the old, damp concrete with a paint brush. Do this right before you plan to pour the new concrete patch onto your old concrete surface. Add the water to the homemade or pre-mixed concrete patch just before applying. Mix it well. Wipe the surface of the concrete with a wooden float.
Apply it to the surface with a back and forth motion until the pieces of gravel have sunk below the surface. The sand and cement should rise to the surface. Allow water to bead and rise to the surface. It will evaporate on its own. For a smoother finish, wait until the concrete is hardening and almost plastic in texture, then apply a smooth back and forth motion with a metal trowel.
Cover your patch with plastic sheeting while it dries. This will keep as much water as possible within the concrete mix and it will bond better. Spray the new concrete with a coat of water every day for 4 to 7 days. This will keep the chemical reaction going and make the new concrete stronger. Method 2.

Not Helpful 0 Helpful 1. What is the quickest-curing material not setting but curing for filling a small hole before putting epoxy paint over the floor? Try Bondo. To achieve a strong bond, lightly scratch the surface of the metal where the adhesive will be applied to. This will increase the surface area allowing for a stronger bond. Clean the surface thoroughly after scratching the surface to remove any loose metal.
Once the surfaces are clean, simply apply the adhesive between metal to concrete and firmly push together. Temporary supports may be required if the items slide down, or use the Adsieal Hi-Grab adhesive for more grab. Adiseal is suitable at bonding most types of plastics to concrete. As with metal, clean the plastic thoroughly to make sure any dust, oil, grease, paint or any other dirt is removed before applying the adhesive. Adiseal is also when used to glue artificial grass to concrete.
Brush of any dust thoroughly prior to applying the adhesive. With Adiseal, priming of the stone, brick or masonry is usually not required as long as the surfaces are thoroughly clean.
A common problem when using other adhesives or glue for stone is they tend to bleed into the stone, as stone is a porous material. Instead of using these other adhesives or glue for stone, using Adiseal will avoid this problem.
