Is water-based varnish easy to clean up?
After use, water-based varnish is easy to clean up. Application of water-based varnish does not pollute. Water-based varnish is difficult to apply when there is humid weather. It does not have a significant advantage over other varnishes when it comes to acid, humidity, water, or heat resistance.
Does water-based varnish Amber over time?
Water-based varnish does not amber over time, and keeps the color of your wood truer than an oil-based finish would. However, it also “flattens out” the wood grain, and unlike oil-based finishes, does not enhance the grain. Instead, just like the color of the wood, the grain tends to look more as it does in its natural, unfinished state.
Can you use water-based varnish on paint brushes?
With water-based varnish, brushes can be cleaned safely and easily with regular soap and water. If you created a custom-painted furniture piece, and you want to protect its surface, consider using a water-based polyurethane instead of an oil-based finish.
Does varnish change the color of wood over time?
However, if you prefer the wood to stay closer to it’s original color (whether stained or unfinished), you would probably prefer a water-based finish. Water-based varnish does not amber over time, and keeps the color of your wood truer than an oil-based finish would.
Which is better oil or water based varnish?
Oil-based polyurethane is more durable than his water-based alternative since it contains a significant amount of Volatile Organic Compounds (VOCs). Those chemicals make the finish tougher and allow it to last longer.
How long does water based varnish last?
three yearsGloss oil-based varnish, polyurethane and Danish oil can last 10 or 20 years, though satin finishes and stains may fail sooner as pigments and flattening agents disable the driers. Water-based coatings and paints can also be viable longer than three years. Shellac, though, can go bad in under a year.
What is the main disadvantage of using water based polyurethane?
Cons of Water-Based Polyurethane Expensive cost. Requires more coats. Scratches easier due to it hardness.
What is water based varnish used for?
Painters not wishing to use solvents can use water-based varnishes, which consist of acrylic resins dissolved in water. These can be used on paintings done in acrylic, or with our Artisan Water Mixable Oil Colour.
Is water based varnish waterproof?
Water-based acrylic varnish Presealer has the ability to act as a primer between the microcement and the varnish, consolidating and waterproofing the substrate.
Can you apply water based varnish with a roller?
It's best to use a brush with natural rather than synthetic bristles for oil-based finishes, and synthetic brushes (often called 'nylon' brushes) for acrylic or water-based varnishes. But you can also use rollers or rags for both kinds of finish.
How long will water-based polyurethane last?
about 3 to 5 yearsDurability and Longevity Water-based polyurethane typically lasts about 3 to 5 years at maximum shine and performance, compared to a varnish or oil-based polyurethane's 7 to 10 years. But that depends on a few considerations: High-traffic areas wear down much faster than areas of the floor that rarely see action.
Do I want oil based or water-based polyurethane?
oil based polyurethane will take about two to three times longer to dry between coats compared to faster-drying water based polyurethane. The water in water based polyurethane tends to “react with the grain” more, so you often need to apply more coats to achieve a smooth, finish.
Can you sleep in house after water-based polyurethane?
No, it is not recommended, and you shouldn't take chances. Polyurethane will be off-gassing heavily for the first 24 hours, even for the water-based type. It is worse if you use oil-based finishes: it's highly toxic and can cause several health problems.
How do I get a smooth finish with water-based varnish?
Always raise the grain on raw wood before applying a water-based finish. Simply brush, sponge or spray on some distilled water and let it dry thoroughly (overnight is best). Then, resand with your final grit paper to break off the whiskers. Now when you apply the finish, the grain will stay down.
Does water-based varnish yellow?
When in doubt, look for something identified as water-based. Since oil is what causes the yellowing, water-based products will not yellow over time.
How long does water-based varnish take to dry?
Average dry times are as follows: Hard wax oils: 4-24 hours. Water-based finishes: 4-8 house. Oil-modified polyurethane: 12-24 hours.

How to get grain off wood before applying water based finish?
Raise the Grain First. Always raise the grain on raw wood before applying a water-based finish. Simply brush, sponge or spray on some distilled water and let it dry thoroughly (overnight is best). Then, resand with your final grit paper to break off the whiskers. Now when you apply the finish, the grain will stay down.
How to make polymer wood look warm?
To get the warm glow of oil-based poly, add a few drops of dye. TransTint Honey Amber is a great product (available at amazon.com). Make a weak solution of dye and water, then stain the wood before you apply the poly. Believe it or not, you can also add dye directly to the poly before you brush it on. A third coloring option is to seal the raw wood with wax-free shellac, then topcoat with water-based poly. Whichever method you choose, experiment on scrap wood to make sure you'll get the look you want.
How to dye wood before applying poly?

How long does it take to recoat polyurethane?
Water-based polyurethanes provide a clear, neutral finish and have low odor. You can recoat them in two hours and clean your tools with water. If you start early enough in the day, you can apply the recommended four coats and sleep in the room that night.
What is synthetic wool?
Synthetic wool is a must-have product with water-based finishes. Traditional steel wool will leave behind bits of steel, which will react with the water and leave rust stains in the clear coat. Synthetic wool comes in various grades and is readily available where water-based finishes are sold. Use coarse to medium synthetic wool between coats. To rub out the last coat, turn to fine and extra fine. Synthetic wool is available at home centers, hardware stores and woodworking stores.
When to apply water based poly?
It's best to apply your water-based poly when the air temperature is between 70 and 80 degrees F and the humidity is below 70 percent. If the air is both hot and dry, the poly may set so fast that it will be difficult to maintain a wet edge as you brush, or the film may not level properly before it sets.
Can you mix oil and water?
Oil and water don't mix. Water-based poly can have adhesion problems when applied over an oil-based stain that's not thoroughly cured. That's why you should always apply a barrier coat of dewaxed shellac to seal oil-based stain. After the shellac dries, a light scuff-sand will leave an excellent surface for the poly to grip.
What is the best polyurethane for high traffic areas?
Oil-Based Polyurethane. Still the best for high traffic areas like floors and heat resistance oil-based polyurethane has a higher solids content which means more leftover materials to seal and coat your wood when everything is dry which is why you can get away with only three coats versus the four coat minimum required with water-based polyurethane.
When was polyurethane invented?
Polyurethanes were invented in the 1930s and have found their way into many home improvement products like foams, glues, finishes, and caulks. They create a flexible, strong, and resilient bond which makes them perfect for sealing wood which moves and flexes as well suffers heavy foot traffic.
Is polyurethane resin good for wood?
Prior to the introduction of polyurethane to wood finishes most varnishes were simply alkyd varnish which created a nice hard finish, but the addition of polyurethane resin to the formula added scratch, heat, solvent, and water resistance to the varnish, vastly improving the life and performance of the finish.
Is water based polyurethane good for sealing?
For sealing projects where you want a truly clear finish a water-based polyurethane is one of the best options because it doesn’t give you that warm amber of the oil-based version. Good for specific projects water-based polyurethane should definitely be in your arsenal if it’s the right project.
Is oil based polyurethane good for wood floors?
For decades, oil-based polyurethane has been the gold standard for finishing wood floors and other wood projects. It creates a hard finish that can stand up to years of foot traffic with minimal care other than regular cleaning. Recently, government regulation has made it difficult or impossible to find these oil-based products in a few areas ...
Is polyurethane oil based?
Water-based polyurethane is technically a misnomer since polyurethanes are an oil-based product. Water-based polys use an acrylic resin just like water-based paints. This resin is hard but doesn’t provide the same protection as the oil-based resin which is far more resilient to wear and especial heat. Below I’ve outline some of the key differences ...
