EASY TO APPLY
TWP Natural Effect Impregnators are easily applied by brush, roller, pump sprayer, or traditional spray equipment. As with any waterborne system technology, they go on milky and they “clear” as they dry. No matter how inconsistently or unevenly applied, the color is perfect even when dry. Special caution should be used in not allowing the impregnator to get on surrounding window frames, masonry, etc. as they penetrate so well that they cannot be removed.
PERFORMANCE
TWP Natural Effect Impregnators are tinted with iron oxide pigments, contain UV absorbers, and are extremely resistant to solar radiation. Their function is to preserve the wood from degradation (UV light, microorganisms, etc.), thus preventing the change in color of the wood, in addition to promoting adhesion of the Natural Effect Finish.

I am having a hard time finding any instructions/articles on applying the Natural Effect impregnating stain plus the top coat (this is on old Ipe that was never stained). I need a super simple overview for the steps after the wood has been prepped. (It has been prepped with the Restore a Deck kit). It has been 48 hours since we completed that but it just rained – and I think it is going to rain on and off for the next couple of days. I know I have 14 days after brightening to stain, or else I need to brighten again. Do I need to wait 48 hours after rain? Then, my second question is, after I finally get the one coat of stain on (with backbrushing), what is the timing of the Top Coat(s). I believe I do 2 top coats – how long after the stain and how long between the 2 top coats (and I think I have to be sure it won’t rain for 12 hours after).
Hello,
Directions are on the PDS for both:

Thank you. I do want to just clarify then, it seems I need to be in a 4 day no rain streak – 48 hours after rain, then I stain and top coat – and then 48 hours should happen before rain comes. And I wait 4 hours after staining to do a top coat and then the second top coat can be done in one hour if it is around 74 degrees (which is likely)? Is it okay to wait a day between staining and top coating or does the top coat really need to be done 4 hours after the stain?
The 4 hours is a minimum dry time, not a deadline — you can wait a day between the stain and the top coat with no issue, as long as the surface stays clean and dry in between. Same with the second top coat: the one hour at 74 degrees is the earliest you can go back over it, not a window you have to hit. Your read on the rain is right — stain on dry wood 48 hours after the last rain, and keep rain off after each coat. Spreading the coats over a couple of dry days is fine and often easier than trying to fit it all into one.
would you recommend TWP Natural Effect be applied over TWP 1500 on a two yr old deck, never treated before with anything?
Both are excellent. You can use either.
Currently using TWP Total Wood Preservative on deck. It is time for a new coat. Would it be possible to transition to the two step system? What type of preparation would be required?
You would need to remove the current coating with this kit:

what would you recommend as far as prepping and product for a house with natural redwood lap siding that was previously sealed with thompsons water seal 3 years ago that still beads water in Pennsylvania. I am looking to preserve the appearance of the natural redwood but want the best protection
Use this kit to remove the Thompsons:

I am considering switching to this stain for my ipe deck. I’ve been using Armstrong Clark exotic hardwood oil for many years. I would clean and brighten the wood before using this stain, but realistically I know I’d not get every bit of the previous oil stain off when cleaning. Would the remaining oil stain affect the performance of the TWP?
-Remove all the AC for best results. It is easily stripped with this kit:

i have 320 sq ft to cover an aged cedar. It says 100 – 150 per gallon. Do u think I’ll be safe w 2 gallons?. Is this good for around water?
3 Gallons would be safe. Yes, you can use it around water.
I was just about to purchase the TWP1500 when I came upon this product. I have seven year old ipe siding that was just cleaned and has never had a reapplication of stain/oil/sealant. The wood has not greyed but there has been some warping,
What is the difference between this product and the TWP1500? I see that it’s a two step process and reapplication seems easier. It does not show up in the comparison chart provided for the other products.
The Natural Effect is the best product we have for hardwoods. Longer UV protection.
We are having a new garapa deck installed and we would like to maintain the color as close to possible. Would you recommend using the Honeytone TWP 1500 Series or the waterbased Natural Effect in the Teak color stain? Or is there another product that would be a better fit. We would like to maintain a honey golden color as much as possible. Thank you
Our best product for garapa is the Natural Effect. Teak is the lightest tint.
Thank you, do you offer samples of natural effect so we can test out the color?
You can call the office to order a sample of it.
We added the samples to the site:

Thank you! Can this be applied to new wood deck or does it require the wood to weather prior to applying? We were hoping to be able to seal it once it is installed.
It has to weather and be prepped.
