Concrete glue is an adhesive specifically designed to adhere porous concrete to other surfaces, a difficult task without the right product. Due to the sometimes complicated nature of concrete surfaces, special formulas are created for each type of material to which you need to attach it. We have a small concrete angel that is about six inches tall with a base of approximately four inches oval in shape, which my wife painted and wants to permanently place on her little sister's grave. To ensure that the angel stays in place, I poured a concrete pedestal for it to sit on next to her tombstone.
While the concrete was still wet, I placed the little angel on it to form a tight base exactly where the angel would sit. I want to use the best type of epoxy, or whichever is the best method to permanently fuse these two concrete elements together. I also hope to seal in moisture to keep these two items intact. This small grave marker will be exposed to all kinds of elements, summer and winter. Can you help us select the best procedure for joining these two concrete elements together permanently? Is an epoxy the best product for this job and, if so, what is the best type or brand to use?An epoxy will work for this application.
I used epoxy at Lowes to successfully bond two pieces of concrete together. There are 2 or 3 different brands, any of them will work fine. This epoxy comes in a tube, consists of 2 parts of 2 different colors, and you mix them to make a paste. Make sure both areas of the surface are dry and clean, apply the paste to both areas and place them together.
After the epoxy has dried, apply a concrete sealant to the concrete (you can get it from Lowes for a small project like this) or you can go to a concrete supply store. The sealant will help protect concrete from the elements. If raw bricks or cement are used, Gorilla glue is usually a quality adhesive; however, if cured or hardened concrete must be bonded with Gorilla Glue, it may not adhere well enough and the bonding agent may even come off prematurely. For smaller concrete bonding projects in and around the house, Loctite Extreme Glue Gel is the best choice. Its highly versatile formula contains Flextec technology that adheres quickly and allows flexibility. It is suitable for indoor and outdoor use, but keep in mind that permanent exposure to water may decrease adhesion. If cold temperatures threaten to wreak havoc on your concrete repair, consider SikaLaTex Concrete Bond Adhesive.
Brush, spray, or spray onto existing concrete surface, or use as a water substitute in a concrete slurry or mortar. Alternatively, use it in a grout mix, a particularly attractive option for tile floors in unheated mud. If you want to bond wet concrete to dry concrete, you will need a bonding agent such as Liquid Nails or another construction adhesive. If water enters the concrete surface and freezes, it can split an otherwise perfect surface with ease. The most common use for bonding cement is to build block walls without mortar joints, but you can also use it to bond two other concrete surfaces together. Even though it is possible to bond an old concrete to a new one, you should do it in the best way possible in order to prevent gaps or cracks from occurring.
Depending on how dirty it is, it is enough to use a pressure washer to remove all traces of dirt and oil from the surface. Then, if you want to patch the concrete, apply a thin layer of cement paint and pour a well-mixed concrete patch into the holes and clean the surface with a wooden float. In Maine where I have been working with concrete for 40 years and this website is where I can share with you all my knowledge and wisdom gained from installing all types of decorative concrete such as floors, siding and stained concrete as well as fixing cracked or chipped surfaces. It is also possible to use an adhesive such as Loctite Extreme Glue Gel for smaller projects around your home as its highly versatile formula contains Flextec technology that adheres quickly and allows flexibility. For larger projects such as bonding metal with concrete or repairing roads you should consider using SikaLaTex Concrete Bond Adhesive which can be brushed onto existing surfaces or used as a water substitute in slurry or mortar mixes. Additionally Gorilla glue can be used when raw bricks or cement are used but if cured or hardened surfaces must be bonded with Gorilla Glue then it may not adhere well enough. Finally if there are unresolved issues with old concrete such as frost or cracks then they can be moved over onto new surfaces by using an effective bonding agent such as Liquid Nails which will not work effectively if there is latitude (a dusty layer of fine aggregates and cement) present on the surface or if it has been contaminated with spills including grease and oil.
