Week before last asked some advice on how to fix Tanalized 50mm thick wood capping onto brick/block wall. (60m of it)
Final decision is to fit with Concrete screws .. Frame Screws
Good suggestion I have had is to insert 5mm thick plastic spacers under wood to keep off brickwork when damp and also allow for any irregularities when fixing .. so may take that approach.
My question is two fold ....... first off at what centres should I put in these fixings ... thinking that 600mm c/s may be suitable ? someone mention 2 fixings every 600c/s but that seems a lot of screws.
I had thought about counter-bore and then plug ...... a lot of effort, if I instead just pulled in screw to below flush and fitted a cover cap. Such as:
Know of a better approach ?
