Cabot's SPF

18 years ago

Has anybody got any experience with Cabot's SPF on Ipe? My paint supplier is recommending it over the Australian Timber Oil. He says it provides greater penetration on Ipe and will last longer before recoating.

You would regret that more than anything you have ever done in your life. Your paint supplier is listening to the rhetoric being dished out by Cabot's technical staff. It is a horrible acrylic that will peel. So far, from what I have seen.. 100% of the time. It is VERY difficult to take off. I am extremely disaapointed that Cabot's continues to recommend this crappy product.

I used the SPF-48 last summer on a new Ipe deck. Followed the instructions, cleaning etc. to a T. The deck peeled in December after snow sat on it for 2 weeks. Now I have hired someone to sand it off and will refinish with Australian Timber Oil. Cabot's tech dep't claimed there were wood fibers in the tape pull samples I sent them, even though their cleaner for SPF says it "removes loose wood fibers." The areas protected from the elements (front porch, under eaves etc,) still look great. If anyone else has had problems with SPF I would like to hear from them.

If your looking for an all Natural Wood, any Hardwood should do fine, more specifically Ipe. Ipe is widely use for Docks and Boardwalks (Atlantic City boardwalk for example) and has been known to last a good 20-30 years and running. As for sealing Ipe (or any Hardwood for that matter) be sure to use a product specifically Design for it, I've had success with Messmers UV Plus for Hardwoods and the Woodrich line up. Also, be sure to use stainless steal screws!

Hi there, Looking for some guidance. Recently bought a cabin in So. Cal mountains. It has a very large, nice cedar deck in front and back that needs maintenance. Received quotes from three contractors and having difficulty sorting through the recommendations. One said the it looked like the deck had previously been stained with a water-based stain based on the peeling. He recommended pressure washing and staining with FLOOD, CWF UV product. We need the siding done too and he said he would mask and do the siding with an oil-based product. Guy two said he wanted to use Cabot SPF (one heavy and one light coat). But in researching Cabot it looks like it has a problem with peeling? Finally, the third guy recommended something called "super deck". They all say they will power wash as prep (though the Cabot SPF guy said he would also acid wash. Would sure appreciate any guidance on with regard to the prep process and any recommendations with regard to the products being suggested. Thanks.

Hi, I used Cabot's SPF-48 Sunray on an Ipe deck about 6 years ago and it peeled badly. It is a water based product that does not sink into wood. Having said that, it held up well on the vertical surfaces, so it would probably do well on a fence. If there are any horizontal surfaces, e.g. tops of fence panels, and you live in a cold zone with freeze/thaw cycles, it is likely to peel off in those areas. In that case the Australian Timber Oil would be a better bet, although you would likely have to reapply sooner than with the SPF. Cabot's recommends cleaning wood prior to staining. Their cleaner is bleach based. You might prefer a sodium percarbonate based cleaner instead. This site: http://www.woodrich-brand.com/ has a good video on how to clean and stain a fence as well as their own sodium percarbonate based cleaner. I can't speak to waiting to apply stain on PT lumber, but most experts here say don't wait. You could ask Cabot what they recommend. Good luck, Marty

All- Wish I had seen this before I did my cedar deck last Fall. I had exactly the same problem. I also sent a sample to Cabot and they said the same thing about wood fibers on the tape pulls.

They actually sent me 4 gallons of SPF36 (I had used SPF24) and 2 gallons of their wood cleaner. Not stripper, mind you, just the cleaner. I have been spending hours looking through posts - thank you pressurepros for all of your responses in threads- I will likely be purchasing some of your Ready Seal in the near future...

I have (almost) completely stripped my deck with a pressure washer and good hard scrubbing. Next will be to brighten and sand. Almost all of the old Cabot stain came right off with the pressure washer. What was left came off pretty easily if it soaked in water for an hour or so and re-hit it with the pressure washer. There are areas where the Cabot actually worked as it was supposed to- mostly hard spots (around knots, routed corners) and it really looks nice. Too bad 99.9% of the deck stain failed.

If you enjoy stripping finishes and watching mold grow beneath your peeling deck stain, Cabot SPF is for you.
