Hi Dale. Can you give a bit more detail on costs, or is this a guesstimate?
Are you using Birch ply? The 18mm ply we got from Fulham Timber was £47+ VAT for and 8x4 sheet last time, but they cursed me and said it would have to be more in future…
EDIT: just read your earlier post! Yes, sounds reasonable! Go for it. We don’t need an exact price.
Osmo is about £50 a tin though…I can pick some up from Leyland, unless someone else is on it?
