About Durata ® The Best Commercial and Residential Wood Countertop Finish

Durata ® finish is significantly harder than Tung Oil Urethanes, and creates a scratch resistant and waterproof surface. It is also highly chemically resistant, even lacquer thinner does not affect the cured surface. Water left on the surface simply dries with no water rings, red wine, vinegar, alcohol, soaps and coffee will not affect the finish. The Durata ® finish stands up to the demanding commercial use at the New York restaurant, Perilla owned by Bravo TV Top Chef Harold Dieterle. Harold chose the finish for the Zebrawood restaurant tables produced by Grothouse because of the high durability. The physical properties of this finish make it perfect for use in residential and commercial kitchens, bars and bathrooms. Durata ® finish is sold applied to Grothouse wood countertops and is not available for onsite application.

Wood Countertop and Bar Top Maintenance and Care with Durata ® Finish

Durata ® does not require recoating like Tung Oil Urethanes, saving clients ongoing maintenance expenses and avoiding the household disruption of counters out of service. Take care to use only dish detergent to clean the surface for the first 30 days until the finish cures to full hardness. In addition, unglazed pottery should have protective felt bases to avoid scratches. Furniture polish is not necessary, and after the first 30 days, cleaning with dish detergent or Green Works is all the care it needs.

Durata ® Food Safe Wood Countertop and Bar Top Finish

Wood Countertops with Durata ® Finish can be used for food preparation, such as rolling dough or making sandwiches. Do not chop directly on the wood countertop as the knife will break the finish and eliminate the protective properties in the process, use a cutting board. Durata ® on bar tops offers a waterproof finish, so spilled drinks and water rings are not a concern. Grothouse also offers the Grothouse Original food safe oil finish for clients desiring to have a finish suitable for direct chopping and use in “Green” environments. It has a flat sheen, and ongoing oiling of the wood creates a deep rich patina.

Durata ® Semi-Gloss Wood Countertop, Vanity and Bar Top Finish

Durata ® Semi-Gloss finish is a sheen level of 55. It has an appearance similar to common household furniture and dining tables, with a shine. Semi-Gloss is the best application for a kitchen or bath countertop with a glossy finish. This sheen is popular for clients desiring a high -shine finish without worrying about excessive cleaning because fingerprints and marks are more visible on a high shone or glossy finish. It is an open pore, meaning the finish is applied in a manner that leaves the wood grain texture visible to the eye and distinguishable to the touch.

Please do not hesitate to contact us if you have additional questions regarding our Durata ® finish.

How to waterproof wood

Inside or outside, wood is always one of the most beautiful materials to use around the home. From floors to furniture, wooden surfaces offer a unique natural appeal that looks as good as it is practical. The only problem is that wood, when untreated, can be easily affected by moisture, sunlight, heat, and daily wear and tear. Finishing and waterproofing wood is very important if you want to preserve and protect your precious wood for a long lifespan. If you are interested to know how to waterproof wood, we will explore the topic in detail below.

Why is Waterproofing Wood Important?

The first thing to understand is the difference between water-resistance and waterproofing. If the wood is water-resistant, it will be able to resist a limited amount of water/liquid. This will help to protect it from small spills which can easily be cleaned up. If water-resistant wood is constantly exposed to water though, it will soak into the wood and cause lasting damage.

How to waterproof wood

A waterproof wood finish creates a tough surface that water just cannot soak into. Here there is no risk for water penetration. Waterproofing wood is used on things like boats or decks that experience prolonged contact with water. Water-resistant wood will work for things like kitchen counters or bathroom cupboards.

Wood is a porous material, so any moisture that penetrates into wood will be absorbed. This will lead to a damaged wood structure. Of course, this is something that differs between different types of wood. If you plan on having any wood outdoors, then it should have some kind of treatment. Otherwise, it will eventually warp, crack, discolor, or rot.

Products that offer the best waterproof wood finish usually have other benefits too. This includes things like UV resistance, and protection against scratches, mold, or any other potential threats to wood. Knowing how to waterproof wood is important for extending its lifespan and appearance.

However, this doesn’t make the wood completely invincible to the elements. You will still have to regularly maintain finished wood to keep it at its best.

How to Waterproof Wood?

You know how important it is to protect and seal wood that is used outdoors, so now the question is how to waterproof wood? There are various products available that can be used to provide a waterproof wood finish. First, you will need to establish whether you will be using the wood indoors or outdoors, and what the extent of water exposure will be.

How to waterproof wood

Then you can choose the best waterproof wood finish based on your specific needs. Knowing how to weatherproof wood will provide a longer lifespan for the wood, as well as a better appearance.

Oil Finish for Waterproofing Wood

Using a wood oil finish is one option for waterproofing wood. There are many different wood oil options available. The kind of oil that you choose should be based on the type of wood that you are working with. Ome good and popular wood oil options include linseed oil and tung oil for general use.

How to waterproof wood

Beyond pure oils, you can also get wood oils that are combined with mineral spirits and polyurethane. This blend helps to speed up the drying time and remove any tackiness from the finish. Wood oil is easy to apply and will help to provide a rich finish that enhances the natural beauty of the wood. This is a good option for many wood surfaces – particularly furniture and indoor surfaces. Some of the advantages and drawbacks of using wood oil are listed below.


  • Oil fills in any cracks and dries hard
  • The oil penetrates deep into the wood
  • A natural solution for finishing wood
  • Restores and maintains the natural aesthetic of the wood
  • Easy to work with and apply


  • Doesn’t provide complete waterproofing
  • Requires fresh applications every couple of months
  • Oil doesn’t provide a glossy, clear finish as varnish does

Waterproof Sealant for Wood

Waterproof wood sealers are available in a variety of different forms. Some of the most popular products include lacquer, polyurethane resin, and varnish. Applying a waterproof wood sealer can be done with a paintbrush, or sprayed with a paint sprayer. Before you apply a coat of sealant, the surface of the wood should be prepared. This includes sanding it down so that the wood is completely bare. You can then add a number of sealant coats until the perfect finish is achieved.

Different sealers contain different ingredients, but they are all chemically formulated. This means that you will want to take a few safety precautions before working with them. Try to wear gloves, protective goggles, and even a respirator mask when applying chemical sealants. Its also always best to work in a well-ventilated environment to avoid inhaling the fumes.

How to waterproof wood

As there is quite a wide range of different waterproof wood sealers, choose a product that is specifically formulated for your use. For example, you can get a special waterproof sealant for wood decks, marine wood, furniture, fences, and so on.

Outdoor wood sealant should also be UV enhanced for protection against the sun. When looking into how to Cwood with a sealant, a marine option is usually best. This is because it has waterproofing and UV-resistant properties.

While shou sugi ban (焼杉板) originated in Japan in the 18th century primarily as way to treat cedar siding to make it weatherproof, the technique—which involves charring a wood surface to render it a deep charcoal-black—has caught on recently as a treatment for contemporary exteriors and indoor furnishings alike. You can even find variations elevated to fine art, as in the work of the artist Maarten Baas. The gravitas imparted by the process and finished result (called yakisugi) are undeniable, a blackening of the wood that reveals clean, distinct lines and an inherent textural beauty. You might not be the proud owner of a blowtorch (yet), but any intrepid DIYer can absolutely accomplish the technique at home to give an existing piece of wood furniture a new look.

I met with Hugh Shackleton and his father, Charles Shackleton, of Shackleton Thomas furniture makers in Bridgewater, Vermont, to learn how shou sugi ban is done. (Though not Japanese, their company has a 30-year history of making handmade furniture, pottery, and accessories, and they leaped at the chance to learn and apply the technique.) Using a prototype for their Sansu Table, made from white cedar sourced from Koenig Cedar in Vermont and built in their workshop, the Shackletons treated and finished the project using the technique in the space of half a day—and are confident that you could, too.

1) Select the right wood

Hugh explained that cedar works best for shou sugi ban because of its natural chemical properties. “Cedar is a lighter, more porous wood,” he explains, and “there’s a chemical component to it which makes it work better for this technique. In this particular design, the bottom is basswood, which still works, but cedar takes it better.” Don't fret if your table isn't cedar or basswood; you can also use shou sugi ban on pine, hemlock, maple, or oak.

2) Burn it

Now the fun part. For large pieces of furniture, you will need a high-intensity flame like an ice melting torch, which you can purchase inexpensively online or rent at a hardware store (and, bonus, will serve you well in any blizzards this winter). “Char the surface enough so that it eats into the wood," Hugh instructs. "When the wood starts to separate, like you’d see on a log in your fireplace, it's done. End grain burns slower than face grain, so pay particular attention to the sides of the piece as you go.” Move the torch evenly over the wood, holding it over each area for about five to ten seconds until it goes black and a layer of soot develops. Be sure to torch in a well-ventilated area with no flammable materials around, preferably outside. Any standard propane tank you would find on a gas grill will work with the torch.

3) Wire brush it

Using a standard wire brush, remove all the char created by the blowtorch. “Be sure to go in the direction of the grain,” Hugh says, and work until all the charcoal dust has been brushed off. The process should reveal a rich, dark, brownish-black color. This is the point in the process where the texture of the grain gets revealed. “You need to be prepared for the characteristic change in the wood,” says Hugh. “Once you wire brush it, it opens up the wood. It becomes more porous.”

4) Clean it

Use either an air compressor or a wet cloth to clean the wood. An air compressor saves time in a pinch because you don’t have to wait for it to dry. If you use a wet cloth just wipe down the whole piece and wait for it to dry completely.

5) Oil it

Hugh initially wanted to finish the table with polyurethane for durability's sake, but his dad Charlie, a traditionalist, convinced him to use boiled linseed oil instead, which contains added drying agents to speed up the process. In a classic family craft business compromise, both men chipped in to help. After the piece is completely dry, apply about a quart of oil liberally and work it into the grain with a rag. Allow it to dry and then apply a second coat to any dry spots. Both Shackletons suggest that you may want to “hit it again with the torch” to seal in the oil once you’ve applied a couple of coats.

The Sansu table, or anything you treat in the shou sugi ban technique, can be used outdoors or indoors and brings a textural depth to a living space. Indoor furniture should require very little maintenance, while outdoor furniture should be re-oiled about every 10 to 15 years. Happy burning!

How to waterproof wood

Since the introduction of the first “click-and-lock” laminate flooring products during the 1990s, homeowners have been looking for types of laminates that are suitable for wet locations, such as bathrooms and basements. Laminate floors have become a favorite of DIYers thanks to their relatively low cost, attractive look, and easy installation, but laminate flooring products earned a reputation for being problematic wet locations. Even those forms marketed as “water-resistant” or “suitable for damp locations” are not nearly as well suited for bathrooms and similar locations as vinyl flooring or ceramic tile. Homeowners who install plastic laminate floors in busy family bathrooms often come to regret the choice.

Generally speaking, the best that manufacturers can do is offer products marketed as "water-resistant," but even these claims are disputable, as the entire manufacturing process works against using laminate flooring in moist locations.

Why Laminate Flooring Isn't Waterproof

The reason moisture is such a problem for laminate flooring has to do with its construction—in particular, its seams and its fiberboard core.

The problem that water creates for laminate flooring is not with the top layer, but with the core, which is little more than a dense type of fiberboard—an engineered product made from wood fibers. If you’ve ever seen a sheet of particleboard in the rain, you’ll know how it bubbles up and crumbles like a wet soda cracker. Complicating the issue is the click-and-lock joining system used in laminate flooring, which makes it difficult to create perfectly tight seams. Seam gaps plus a fiberboard core equals a flooring that will swell and delaminate when water seeps past the surface layer.

One little-known aspect of this moisture-and-laminate issue is that the moisture problem actually starts in the factory, not in the home. Flooring manufacturers have found that high moisture content in the fiberboard particles in the factory can result in poor adhesion of the top melamine wear layer.

Attempts at Solutions

For most of the time that laminate flooring products have been marketed for residential use, the industry advice has been to avoid installing them in moist locations, such as basements or children’s bathrooms. Even the better products that have thick surface layers and are engineered to have close-fitting seams will almost always carry warnings regarding water, such as Armstrong’s typical warranty caution, which notes that the flooring “[w]ill resist topical water damage, meaning that planks or tiles will not swell, delaminate or peak at the seams due to topical spills, provided that the liquid is wiped up and the floor is allowed to dry.”

In other words, laminate flooring loses its warranty coverage if routine spills—or even melting snow or rainwater from shoes and boots—aren't wiped dry immediately. And this is no long-shot scenario. The most common cause of problems with laminate flooring is when moisture penetrates the seams and causes swelling of the fiberboard core and delamination of the surface layer.

With anything beyond a topical surface spill, such as a spilled glass of water or water dripping off your legs when stepping out of the shower, a laminate floor is in serious trouble. An overflowing washing machine, a leak on a refrigerator water line, even condensation dripping from the tank on your toilet, can cause the serious failure of a traditional laminate floor.

In an effort to expand the market, manufacturers have tried to develop true “waterproof” versions. These usually involve factory application of a thick waterproof coating to the tops and sometimes the edges of the planks. But generally speaking, the warranties on most of these products make it clear that they are by no means “waterproof,” and at best can be described as “water-resistant.” The warranties have many restrictions, such as cautioning against installing the flooring in humid conditions, placing heavy objects such as refrigerators or kitchen islands on it, or leaving water puddling on the floor for more than 24 hours.

Other companies have altered the formulation of the fiberboard core, introducing more resins into the fiberboard in an effort to make it less susceptible to swelling and delamination. But virtually all of these products come with significant limitations and warranty clauses that make it clear they fall well short of being truly waterproof. The products can be made more water-resistant, but no laminate floor that utilizes a fiberboard core can ever be said to be truly waterproof.

There are, however, a few companies that offer products that have a more legitimate claim. For a truly waterproof floor, the flooring material must be engineered with a different type of construction that eliminates the fiberboard core altogether. A few manufacturers offer laminate flooring products made entirely of PVC plastic, and these products are completely suitable for basements, family bathrooms, and other wet locations. However, compared to the hundreds of styles available in fiber-core laminates, selections are severely limited when it comes to truly waterproof laminate flooring.
