Frequently Asked Questions:

Can I use Pro-Wrap with concrete or Postcrete?

Do I need any special tools?

Just a standard blowtorch or heat gun is enough.

It takes about a minute per post to apply.

What kind of wood should I use?

UC4 treated timber is recommended to qualify for the 20-year guarantee.

Will it work on round or square posts?
