my fence was built 2 years ago. what preparation do i need to do before applying Techniseal? Also, how often would i need to re-coat the fence in the future?
A coating of this product should last at least two years before a reapplication is required. For optimal results, start by stripping/sanding the wood to work on a completely "naked" substrate. Then, clean the surface with our Wood Cleaner before applying the Stain & Sealer. IMPORTANT - Always work on a dry surface, with no rain forecasted in the 24 hours following application.

Deck with 3 year old thecniseal wood protector .Procedure to apply a new coat .Clean only ? Pressure wash ? Sanding ? Or .....some thing else? Thanks
Here is the recommended procedure:
1) Clean the entire surface with Techniseal® Wood Cleaner (60102038), as directed on the product label.
2) Smoothen rough surfaces with an 80- to 120- grade sandpaper. Remove residues with a vacuum.
3) While sanding the entire surface is not mandatory, it will provide a smoother and more uniform finish.
Note: Rust-proof nails and screws should not be apparent.

Can I use it on raw natural non treated wood, like cedar?
Unfortunately, we do not recommend applying this product to cedar and similar types of untreated wood.
As a means of natural protection, cedar secretes a special oil that can affect the adherence of products such as our Wood Stain & Sealer.

I've applied the first coat of this product to my deck. Can I apply 2nd coat because some area appears thin? How long do I wait to apply the second coat? Thanks!
Our wood protector was developed for a "one coat" application. Adding a second coat is possible, but it must be "wet on wet" and done within a few minutes, while the first coating has not yet dried up.

Bonjour, est-ce sécuritaire d’utiliser ce produit sur une table en bois massif d’acacia pour l’extérieur?
Oui, il est cependant fortement recommandé d'utiliser un nettoyant pour bois, et de traiter la table avec notre préservateur. Cela permettra d'obtenir des résultats esthétiques et durables.

Fantastic color
The guy at Rona recommend this product to me so I thought I would try it. I picked the color CEDAR. It turned out fantastic. The color is rich and warm, lots of character in the knots of the wood when put over pine. Stained the front porch, stairs going down to my tenants house & also the lattice e on the fence. Super happy with this product. There is no odor either.

Not diy friendly
This product was not great. I put this on a pressure treated deck and a pressure treated garage door pergola. The colour variation between the 2 projects was extremely different. Both projects were stained from the same can of stain. The stain did not permeate into all wood the same. So some boards look dark while others appear time worn after only 3 weeks. Normally with other brands of stain I would just add a 2nd coat to achieve a uniform look. This product does not recommend a second coat. This stain was a waste of time and money as now I have to sand everything down and retain with another product.

Mr
Bought this product instead of Thompson's Water seal because of reviews. So glad I did. Applied it onto the pieces of a cedar picnic table before assembly. Also a couple of coats after installation. Really brings out the grain of the wood with a nice cedar shade. This table will now probably outlast me....

This is junk. Did not last one rain fall
Looks like the money I spent on Techniseal Maintenance-Free Wood Protector (Item #000341421 Model #144-353) is all gone in the water. This product is a junk and it didn’t last one rain fall.
I have completely sanded my deck down to bare wood, cleaned with the Thompson’s cleaner and brightener waited for 48 hours for it to completely dry, and then applied the Techniseal stain and sealer. It was beautiful until the rain falls. It seems like the water is being absorbing through the sealer into the wood. The wood getting darker and darker with the water getting into the wood. OMG! This is heart breaking!
Have I put lot of effort and so many hours in to this project in order to have this crappy result? I not only wasted money on the sealer, but also 20+ hours! I am extremely disappointed. I need my money back so that I can get something else.
