review of rad system and twp #516 on ipe deck
Wanted to write a fairly extensive review so that everyone knew the entire background of the deck and its exposure limits.
Started building my two tier deck back on August 1st, 2005. The deck was to be a 12x24Â upper deck and a 8Âx 8Â lower deck. The upper deck was 33" above grade and the lower deck was anywhere from 7"-12" above grade due to the sloping nature of the yard. The deck contruction was beam atop posts.
I bought my lumber from Advantage Trim and Lumber in NY (aka IPEDEPOT). Ipe came in great condition with only 3 boards damaged and was the thinner 1x6 decking (not 5/4"). All lengths were exact (12Â or 8Â) so that NO butt joints were needed. I used the IPE clips from Advantage Lumber.
Overall I am happy with the resultsÂalthough the lower deck as warned by J Hyatt an others has a few boards that cupped a littleÂ.even though the deck was ventilated with four vents.
The decking was completed in late September of 2005 and all that remained was trim work and a hip wall planter in place of railing on one endÂ..so in my spare time I worked on thatÂ..so the deck sat untreated from September 2005 till July 21st 2006Â.of course it saw a northeastern winter with several snowfalls and one ice storm and PLENTY of rainfall. The deck weathered and you could see water soak into the boards.
So it was time to complete the project last week and yesterdayÂ..so I took pressurepros (Ken) RAD system and followed the directionsÂfirst the sodium percarbonate "stripper"Â.WOW is all I can sawÂyou should have seen all the bubbling action!!! It looked like the head on a beer!! (we get a few weeks here where everything is covered in yellow pollen!)Â..with just a garden hose and a stiff bristle brush the grayed wood just washed away!!!! I performed this early in the morning while the deck was shaded to prevent drying out and minimize the need to mist with more solution. I know you always see those before and after pics but here are MY OWN pics and it TRULY works!!!
Followed that with the second step (neutralizer/brightener)Â.again WOW brought back the color of the original deck and made it a bit lighter on some boards. Truly a remarkable product for restoring 1 yr old untreated IPE back to a more rich toneÂbut it did need stain/sealant to finish off that look.
In comes J Hyatts famed TWPÂ.because I was in NJ I could only get TWP #516Â.the high solids version of his TWP #116. Directions stated to use ONLY ONE COAT ON NEW WOODÂ.so I forwent the "wet on wet" treatment touted by John with his #116Â.I used a brush for minor trim and 10" lambswool application pad on a pole. I ran down 4-5 boards at a timeÂ.being careful ALWAYS to keep a wet edgeÂ.by the way it was mostly sunny with a cloud here and there high of 88 degrees and 62% humidity. The stain went on flawlessly with little effort and soaked right in like a sponge!!! Very little stayed "floating" on the surfaceÂ.I made a few passes to try and get a semi-wet glossy appearance to ensure full saturation and then a few passes with the applicator to feather out any possible lap marks and soak up obvious poolsÂ.I started the process at 8amÂ..made it to the end of the upper 12Âx 24Â deck by 12pmÂ.about 4 hoursÂ.the stain had a slight glistening to it but no poolingÂ.went back to the first boards and felt the stain and it was oily but NOT TACKY AT ALL after 4 hours!! So it seems that even in full sun at 85-90 degrees flashing of volatiles is not occurringÂhowever, make sure to keep a wet working edgeÂthe very fist dip of the pad I had a few drops hit the deck and got to them about 2 minutes laterÂa quick pass over them and they were still apparentÂ.but like John H. said you can "burn" the coats togetherÂI rubbed the pad firmly over the spots with more stain and it evened out to where the spots are not noticeableÂ.I could have gone back and tried to put more stain on and see if that would have soaked in but was worried about the one coat claimÂ..so it appears J. Hyatt you could easily do your wet on wet with this #516 even hours after initial application! Seems to be fairly slow to set upÂ.I would have figured with higher solids and lower solvent it would be the reverse but apparently not soÂÂ.I took a spare board and applied this wet on wet (30 minutes between coatsÂ.1st coat was still oily and not dried or tacky) and am awaiting results today. I finished up the lower deck and all the facia boards and vents by 6pmÂschewwwwwww what a long day!!!.....but the color looks great!!!!Â.at about 8pm there were a few what I would call shiny areasÂnot pooling or defined spotsÂ.but undried stainÂ.went back and smoothed out with a brush and some spots remained this morning but obviously drying and drying such that they do NOT remain shinyÂ.a few spots looked liked they could use more stain but when brushed with more did not take anymoreÂ..Should hopefully by 100% dry by this evening (~24 hours)Âdirections on the can state 24-48 hour dry time depending on wood and environment/weather. Update- hope it is dry as storms rolled in last night so minimum dry time was 26hrs and 23 min....I'll post update pics of deck after rainwater dries up
So I donÂt know if things would have been different had I stained/sealed it right away but I can say 1 year old Norhteastern weathered IPE soaks up that stuff like a sponge after the RAD treatment!!!...you put the brush down and you could actually see the capillary action pulling the stain out away from the brush!! It will be interesting to see how long the color lasts with one coat and how dark the next will be if applied directly without any RAD cleaning actionÂbut IÂll decide that laterÂ.now all I want is to enjoy a nice tall cold one on my IPE deck!!!!
So as it stands now I am EXTREMELY SATISFIED with KenÂs RAD system and J. HyattÂs TWP recommendationÂ.gave a GREAT colorÂI was a little worried that it might be too dark using the higher solids productÂ..when poured into a paint tray it was jet black!! (see pictures)Â.brown in a thin layerÂ.
but despite that it lets those brilliant reds through the IPE and looks wonderful!!! Thanks a million guys!!! If you were closer IÂd buy you a beer or (tecate!) John!! But Ken IÂm in Philly often so you could take me up on that offer!!!...
