What is the Best Glue for Gluing Concrete to Concrete?

For smaller concrete bonding projects inside and outside the home, Loctite Extreme Glue Gel is the best choice. Its highly versatile formula contains Flextec technology that adheres quickly and allows flexibility. There are many reasons why Adiseal construction adhesive & construction sealant is the ideal product for bonding items to concrete. Most epoxy glues for concrete come in two-part systems consisting of an epoxy resin and a hardener.

When equal volumes of resin and hardener are mixed, they react to produce a strong, rigid, high-strength bond. You can use epoxy resin for concrete to repair, fill, bond and rebuild concrete surfaces. Concrete glue is an adhesive 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 will have to attach it.

In fact, you can use a construction adhesive to glue metal to concrete, fix crumbling roads and even garden stones. Whatever the job, there is a sticker to help you do it. If your project requires smaller repairs or quantities of glue, opt for the caulking technique. All you have to do is prepare the space, add the cartridge to the caulking gun and run the applicator around the perimeter of an object. Press the pieces together and follow the instructions on how long you will need to cure the concrete glue.

The E6000 multi-purpose adhesive glue

is the most powerful adhesive glue you will ever find.

This industrial adhesive e6000 is even twice as strong as polyurethane products. Concrete has been one of the most important building materials of all for decades. Its areas of application are diverse, which makes this material interesting not only for industry but also for home users. Not only is the casting of concrete important, but also the bonding. For this purpose, various adhesives for concrete are available on the market today.

In our guide to concrete adhesives, we will show you how to use them optimally, how to glue wood to concrete. Precisely because of the many benefits of this product, we wholeheartedly recommend this epoxy adhesive from PC Products. If you want to bond wood to concrete, a two-component concrete adhesive may be useful. A two-component adhesive is also an invaluable aid in bonding other materials, such as thermosetting plastics or bare metals, to concrete. If you want to apply insulation to concrete, you should also use a two-component concrete adhesive, as it is perfect for insulating foams.

It is essential to use an adhesive that is flame retardant and solvent-free. The surface of very smooth materials must always be rough before processing.

This 100% polyurethane adhesive

is safe to use and complies with VOC requirements. You can use this product in indoor and outdoor applications with the assurance that the bond will last as long as the surface to which it was applied. In fact, this polyurethane adhesive is up to eight times stronger than most other construction grade adhesives and is an excellent choice for bonding a wide range of building materials. This product is waterproof, dries in cold weather and can be painted once cured.

Before you start joining concrete, you need to consider some points. First of all, the required adhesive strength should be determined, since the available adhesives have a wide range of adhesive strength. Sometimes, only one adhesive with a relatively low bond strength is needed. This is often the case for smaller joints.

Only after these questions have been clarified, can the adhesive be applied. This depends on the type of adhesive used. We will introduce them to you below and we will go into detail about the respective application.

The assembly adhesive

is usually strong and suitable for both indoor and outdoor use.

An included bonding tip makes it easy to apply, so even very small glues can be applied without any problems. At this point, we recommend Gorilla Heavy Duty Ultimate construction adhesive. This has a particularly high adhesive strength, as well as many other advantages. This is a very durable product from the Gorilla brand that offers a strong and versatile adhesive that can be used on many different surfaces.

It is completely waterproof and can even be used on underwater surfaces. This adhesive works instantly and can also be used as a gap filler. You can also paint on this adhesive. With a slight disadvantage, this Gorilla mounting adhesive receives a clear recommendation from us.

Especially when concrete is to be bonded to other materials, a good assembly adhesive is usually used. It has high adhesive strength and can therefore form extremely strong and stable bonds. It is therefore ideal for replacing dowels, screwing and drilling. Especially when these methods are not possible, bonding with an assembly adhesive may be an optimal alternative.

At this point, we can make a clear recommendation for PC-11 epoxy adhesive paste PC-11 from PC-Products. This two-part epoxy adhesive paste is marine grade, which means it can be bonded to materials in dry, wet and even underwater areas. You can apply this adhesive to vertical and aerial applications both indoors and outdoors with ease. This adhesive paste is also resistant to mild chemicals, oils, as well as fresh and salt water.

With a longer working time, this is the ideal product for use on larger projects that require repositioning or changes. We have tested silicone based adhesives for concrete and the clear winner for us is the silicone for concrete & masonry from General Electric (GE). This adhesive is resistant to UV rays and sun heat, as well as frost, and may rain a few hours after curing. In fact, you can use this product on various surfaces to achieve a permanent and durable yet flexible bond.

This silicone adhesive is waterproof and will not shrink or crack. This is the ideal product for sealing concrete, as it has a wide range of great advantages making it an excellent choice when gluing concrete surfaces together.
