Here is another question asked by a member of the public relating to timber treatment. We hope that it and the answer, which we include below, are useful.

Would Pro-bond 2000 (clear) be suitable for sealing acrylic windows to GRP substrate, namely boat windows? The windows are applied from the outside and secured with stainless steel screws/nuts. I have heard it is a good idea to place some nylon washers between the acrylic and the GRP to stop the sealant being completely squeezed out.

Here is our answer:

Pro-bond 2000 is used for this application. Ideally you need a gap to prevent the sealant being sqeezed out to give 1mm thickness.
