Treating your Wood or Deck with transparent "tinted" Deck Stains will create a UV absorber, filtering out the damaging sunlight and preserving the natural color tones.
There is now a new sealer on the market for wood and decks that is completely unique. This new product is a one time application that will petrify your exterior wood, PERMANETLY!
CretoWood is a permanent wood sealer for exterior timber and decks like no other. I was developed to permanetly harden the interior of the wood. The catalyst in CretoWood allows deep penetration within the layers of cells inside the wood CretoWood reacts with both the acids and the alkali present in the individual cells of most woods forming an aero silica gel on the surfaces of the cell walls. This cellular membrane forms an internal seal and barrier against water and other causes of deterioration. The 6 to 12 months following, silica gel membrane formed will turn into glass petrifying the wood treated and is effective whether applied on surfaces which will be above or below grade.
CretoWood is intended to prevent internal rot and decay. It will not stop the Sun's UV rays from discoloring the wood or prevent dirt or mildew. You will need to clean and treat your wood with a tinted stain/seal on a regular basis if you want to prevent the wood from turning gray and retaining a clean appearance. CretoWood will not hinder any top stain/sealers from properly penetrating the wood. It will not create a film on top of the wood. In many cases it can extend the life of you tinted deck stain dramatically by stabilzing the cell structure that your finishes adheres to. You can use CretoWood on any type of wood structure that is prone to rot or decay. Examples would be: Wood Houses, Log Cabins, Wood Decks, Wood Docks, Wood Fences, Wooden Window sills, etc.
Finally there is an answer to exterior wood rot and decay and it is CretoWood, as Permanent as the Pyramids!
I have a cedar fence that has never been treated or cleaned. Do I need to clean first before using the Cretowood? If I do clean will it turn gray again?
How is this material to be applied? Can it be painted on or does it require submersion in the liquid preservative?
The Cretowood is very easy to apply. A pump up type sprayer is the best way. Just apply to all visible areas of the wood. The wood should be clean and free of any previous coatings. Best to apply to wet wood. Make sure that you do not get the Cretowood on any glass, aluminum, or fiberglass trim. It can etch these surfaces.
"This product has been used all over the world" is not a REFERENCE, nor a TESTIMONIAL. I need names to contact. My church board will not consider applying a new technology product to our cedar shingle roof without some solid proof of its effectiveness on cedar roofs. This is a large investment for us.
I apologize if my request sounded rude; that was not at all my intent. Yes, I have contacted Creto.net, with no response. I was hoping that, since you are a retailer of CretoWood, you might have had some feedback from your customers. I am just trying to get some references to contact. That is what our Board wants, which I think is only reasonable, given the large investment (and even possible damage to a very expensive roof if the product is not good).
To further explain: the Cedar Shake and Shingle Bureau (http://www.cedarbureau.org/installation/care-maintenance.htm) publishes a maintenance brochure which says one should NOT purchase a product which "makes outrageous claims (such as lasting for 10 years or longer)". None of the local roofing contractors -- including the contractor which put our roof on -- has ever heard of CretoWood, and they're extremely skeptical. In addition, the engineering firm which acquired for us the Historical Society grant which allowed us to install the cedar shingle roof recommends a traditional product. I was a college chemistry major, and I think the science behind the product is very compelling, but I must convince a very skeptical board. I am fighting an uphill battle, and am admittedly frustrated; that may have come across as rudeness, for which, again, I sincerely apologize. In addition to the roof, I personally have a wood fence around my home which needs sealing. If any of your customers who have purchased CretoWood could tell me of their experience with the product, I would be grateful. Thank you!
The Cretowood product information says that the product will expand when it freezes. If I plan to use on a new wood deck that will certainly be below freezing temperature in the winter, should I avoid this product? Or is the freeze threat only in the raw, unused product?
