About 2 weeks ago, I applied Defy Stain for Hardwoods as directed, or I tried to. With diagonal board decking that wrapped around a corner, it was difficult to apply within "natural breaks". With environmental sensitivities I wore an industrial respirator type mask and I used a stain stick, which allowed me to apply Defy while standing upright.
The directions say it is important to apply a second coat while the first is still wet. A time range of minutes is referenced. Using a minute timer, I followed the directions, covering the wet with new wet within the suggested time frame; but it was difficult to determine when, exactly, would be the ideal time for application. At the time of the application, coverage looked even, but 24 hours later, there were places that looked poorly covered and some places that looked blotchy from over coverage. I tell myself it is just a deck and that if there has been sufficient penetration, that is the most important thing. But of sufficiency of penetration, only time will tell.
Also, coverage is described in square feet. The coverage description does not say it is for 2 coats, but since 2 coats are required, I doubled the surface area to figure how much product to buy, which resulted in my purchasing twice the amount of the product that I would need. In fact, I had not read about applying it to the underside of the deck. Since my deck will have a roof, that will not be necessary, but if the coverage that was quoted included both the top and bottom, 2 coats each, I probably bought 4 times the amount I needed! This appears to have been the case! In time, I will be able to use the balance, but in the meantime, finding storage for the huge container will require some creativity!
Can I recommend this product? It is too soon to tell. Ask me again in a couple of years when I have seen if it has worn well.
