Tips for effortless attaching of wood with concrete without drilling
Sweep or vacuum the concrete surface to remove any dirt or debris. Cleaning the surface before applying any glue is very important to let it work effectively.
Wipe the surface with a damp sponge to remove dust. Allow the concrete to dry completely. Any dust on the surface may reduce the strength of the glue which will not let the wood attach to the concrete properly and may lead to weak joints.
Cut the tip of the glue tube so that a line of glue comes out about 7mm wide. Load the tube into the caulking gun. this way there will be less time of air contact in the glue which will help in more effectiveness.
This is the most important step that must be done with perfection for better results. Make a line of glue on the back of the wood, this is the surface to be applied to the concrete, 1/2 cm from the edge so the glue doesn’t squeeze out.
