Flexible flooring adhesive is a type of glue that you would use when bonding your wood or bamboo floor down to the subfloor. It has been specifically designed to be used with both solid wood and engineered wood floors. If you are having a new wooden floor and are thinking about gluing it down, here is a bit more information about flexible flooring adhesive:

Why do I need flexible flooring adhesive?
When gluing your wooden floor down to a concrete subfloor, you need to use a glue that is strong whilst allowing the wood to expand and contract with changes in the environment. This is designed to do exactly that.
A wooden floor is a natural product so will react to changes in temperature and humidity. When the surrounding air is warm and humid, the flooring will naturally absorb some of this moisture and may expand. Similarly, when the air is dry the moisture in the planks will disappear and can start to contract. Slight movements like this are perfectly natural and occur throughout the year with the changes in seasonal temperatures.
It gives a tight and secure fit whilst allowing the planks to move as they need to. If they were fixed rigidly to the floor and were not given the flexibility to move, they may start to break or rise up.
Which type of glue should I use?
One of our favourite flexible flooring adhesives is Sika MS Flexible Wood Flooring Adhesive Tub. It is applied using a trowel to create a full surface bond. Another great product is Sika 52 Wood Flooring Adhesive Sausage which is applied using a barrel gun. Both adhesives are suitable for any engineered wood flooring. However, you can only glue solid wooden flooring which is less than 150mm in width. If you have a solid wooden floor wider than 150mm, we would suggest using a stronger adhesive like Sika T54 Flexible Wood Flooring Adhesive.
