How to attach wood to concrete
- Reduce gap
To get a strong adhesive bond between wood and concrete, minimising the gap between the two surfaces will provide a better bond. This can involve cutting, filing or sanding the surface to get both surfaces even.
- Clean surface
Prior to applying the adhesive, it is vital to have clean surfaces where the adhesive will be applied between the wood to concrete. Make sure both surfaces are free from any dust, grease, paint or any other dirt. Using a fine brush like a painting brush will help remove fine dust.
- Apply the adhesive
When attaching wood to concrete with Adiseal, simply apply the adhesive between the wood to concrete and firmly push together. If there is potential of water in the area the item is being bonded to, Adiseal needs to be applied in thin vertical strips. This allows any water to run down between the strips instead of building up behind the item. In cold temperatures water will turn to ice which expands and pushes the surfaces apart.
- Temporary supports
There should be no need for temporary supports to hold the wood to concrete but if the wood does start to slide, then temporary supports may be required until the adhesive has cured. Adiseal can take 24 to 48 hours to cure.

Glue for concrete
It is also possible to glue to concrete using our Adiglue glue. Although Adiglue is less brittle than super glues, it is still not as flexible or strong as Adiseal construction adhesive & construction sealant.
In the example below we have glued a metal handle to a heavy concrete slab with the Adiglue glue. The concrete required sealing first with Adiglue Activator so that it does not soak up the Adiglue. Sealing is not required when using Adiseal construction adhesive & construction sealant to stick the same metal handle to concrete.

Cleaning concrete surface before applying the adhesive
Before applying an adhesive to concrete, make sure the concrete is thoroughly clean. When concrete is exposed outdoor, a layer of dirt can build up on top of the concrete. This dirt layer sticks to the concrete surface. Simply brushing the concrete is not enough to remove this dirt layer. If an adhesive is applied on top, then the adhesive will only stick to this dirt layer and not the concrete.
To clean the concrete, we recommend using a jet wash or sand blasting the top concrete surface. It is also possible to use a detergent or cleaning product and water mix, together with a thick brush to help remove this dirt. This method is not as good as using a jet wash. If the concrete has been cleaned with a detergent, rinse thoroughly to remove any cleaning agent. Fine dust can be removed with a vacuum, blower or a fine brush like a painting brush.

Frequently Asked Questions About Concrete Adhesive
Adiseal is the best adhesive to use on concrete as it has proven to be the strongest adhesive by an independent test. Adiseal is flexible, waterproof, high gap fill, high grab, UV resistant and sticks almost any type of material to concrete.
Making sure both surfaces are clean of any dust, grease, paint and any other dirt is vital before applying the adhesive on to the surface of the item being stuck to the concrete.
To remove adhesive from concrete, use a sharp item like a knife or chisel. Usually chemical adhesive removers will not have any affect on concrete adhesive.
As concrete is a porous material, it will soak up any liquid glue or adhesive. With Adiseal this is not required as Adiseal will not soak into the concrete. If the concrete does require sealing, use Adiglue Activator.
Adiseal adhesive & sealant can be used as an wood to concrete adhesive. It will provide a strong, flexible, long lasting and waterproof bond. Adiglue can also be used when gluing wood to concrete. When gluing wood to concrete with Adiglue, the concrete will require sealing first as it is a porous material.
