Deck

Posted 500 days ago

Hi

I have a decking oil problem and would appreciate any clues. A week ago I oiled my deck. The next day I went to put the second coat on as recommended on the tin (Wattyl Estapol Timber and decking oil) but found that as soon as I applied it a scummy residue appeared. I rang the Wattyl customer service line and was told that this had occured because I had not left enough time for the deck to dry after I had mopped it and had locked water into the wood which seemed to react once the second coat was appplied. But I do not believe this to be the cause as there was part of the deck which I did not apply the oil to until the next day (ie 36 hours later) which still seems to react in exactly the same way as soon as I commence the second coat - it is a frosted/bubbly reaction that I can scrape off with my fingernail. The Wattyl hotline are still of the belief that it has something to do with water in the wood and believe it is mandatory that I put the second coat on but I know it will go all bubbly. They recommended I sand the whole lot back and start again - this would be an enormous job as the deck spans the entire stretch of the house. My inclination is to not worry about doing two coats and to leave it for 6 months to allow the oil to evaporate and do another coat then. Has any one had a similar reaction when they have gone to apply the second coat.

Would be interested to know.

Thanks, deb
