We recommend the use of our 8mm fibreglass reinforcement bars for when additional strength is required e.g around a worktop cut out for a sink or hob.

These should be put into the back coat where you are using a two coat process of a face coat and back coat. If using our pre mix kits these should be the last thing added to the mix - placed on and gently pushed in around the cut out.

The bars should be pushed into the concrete just below or on the surface - pushing them too far in will result in them being visible in your top coat. We would recommend two bars in front and two bars behind a cut out.

The bars are 8mm in diameter and come in standard 1.4 metre lengths. They can be cut to desired length with a hack saw.
