If you are setting dry treated wood as posts in concrete in sandy soil , would painting the wood with oil paint make it last longer ?
Ok , I'll ask at Menards.
I would think that would work , i used some stuff i got from work like that and the fence is still standing almost 30 years later i smile every time i drive past it (sold the house in 96).
Where would I get tar ? The roofing patch stuff in gallon cans ?
Coat it with tar and go above the concreat line
If it’s anything like solid color stain it might just flake off as the wood expands and contracts. I was always told to put some gravel down first and set the end in that so any moisture can get out. Make sure the end is not covered in concrete, otherwise it may hold moisture.
