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

I am in the middle of a self build barn conversion in Cornwall. I have all the old floor boards which I removed at the beginning and stored. I want to treat them for woodworm but I am not sure what to use. I want to sand the floor when it is installed and use a water- based lacquer to finish. The area is approx 20 sq m.

Here's our answer:

I would spray or brush the timber with Micro 8I. This product dilutes 1 to 24 with water which will easily cover 20 sq.m
