Re: Ronseal or Creosote
Hi
There are various types of treated timber, the cheapest ones are just dipped in preservative, water based.
The stuff you buy from the DIY sheds.
The next one up, is pressure treated, the timber is placed in a large container, the air drawn out and the preservative , water based, is drawn into the wood by the vacuum.
The cheaper pressure treated stuff only has a partial vacuum, is not kept in for long and water based preservative is used, it is much cheaper to buy and to dispose of the waste.
The preservative only goes in a few mm.
The good stuff is treated under a high vacuum, for a much longer period of time, using more expensive spirit based preservative.
It then has to be air dried for weeks,.
More expensive initially, but will last 30 years, doesn't need retreating or painting and no rotten posts to replace.
Far cheaper and much less hassle in the long run.
There are various grades of treated timber, the one I use is known locally as marine grade.
We used it to build Fishing Pegs in the River Severn, half immersed in water in summer, regularly totally immersed in winter.
The pegs were put in 23 years ago, still as good as new, no rot at all.
Very good for fencing, sheds etc.
Reading this, I am coming to the conclusion that I must be the most boring person I know.
