Before getting upset, check whether the polyurethane has actually dried. If you’re using water-based material, it’s common for it to appear milky before it dries. The color comes from the emulsion that carries the resins. If the finish is still wet, just wait — the milkiness should disappear.

Why does my polyurethane look white?

White spots on polyurethane are generally caused by two things: Not stirring thoroughly enough before applying it, or a buildup of moisture. While preventing the white spots is easier than fixing them, you can fix them by sanding down the high spots and then drawing out the moisture.

Why does polyurethane look cloudy?

Cloudy finishes appear for several reasons, including using an old product or one that’s been stored in a very cold or hot environment. Proper application also requires stirring the polyurethane coating immediately before placing it on the surface, which should be clean and oil-free.

What color is polyurethane?

Natural polyurethanes vary from a light tan (almost yellow) to a medium-dark amber (almost greenish). This variation is noticed from supplier to supplier, and even within a given supplier’s production.

What color is water polyurethane?

COLOR: Oil based poly has an amber hue, whereas water based poly is clear. An oil based polyurethane will continue to amber and darken over time, while water based poly will remain clear for the lifetime of the hardwood floor.

How do you fix Milky polyurethane?

Remove milky watermarks from a cured varnish or polyurethane finish by spreading a thick coat of lemon oil or petroleum jelly onto the affected area and leaving it there for 24 hours. They have a greater affinity for oil-based finishes than water and may soak in and replace trapped moisture.

How do you fix cloudy wood?

Soak a clean, soft rag in mineral spirits. Wipe the cloudy area with the cloth, using long strokes that match the grain of the wood. The wax finish should start to look hazy and dull as it is being removed. Work in small sections if there is a large area of cloudiness to be removed.

Does polyurethane come in colors?

Yes, polyurethane can be found tinted in different shades. Tinted polyurethanes can be applied over a primer or on natural wood. The effect you get with a tinted polyurethane is not quite the same as its uncolored counterpart. Keep reading to learn more about finishing with colored polyurethane.

Why is polyurethane yellow?

What causes hardwood floors and polyurethane to yellow? Oil based polyurethanes turn the floors yellow…and over time, they become more yellow…and sometimes even a bit orangish. It’s the UV rays from the sun that turn them a darker yellow or amber and the more they are exposed over time, the yellower they get.

How can you tell the difference between polyurethane and lacquer?

Dip the corner of a clean, soft rag into lacquer thinner. Rub the hidden area on the floor or furniture. If the surface layer dissolves, the finish is lacquer. If the surface remains unchanged, the finish is polyurethane.

What does water based polyurethane look like?

Water-Based Polyurethane Pro tip: They appear milky in the can, but go on clear and remain clear. They’ll slightly accent the character of your wood without giving it the amber tint of an oil-based poly. (However, some woods, like the oak shown, cry out for that amber tint.)

Does water based polyurethane darken wood?

An oil based polyurethane will continue to amber and darken over time, while water-based poly will remain clear for the lifetime of the hardwood floor. This color difference is less noticeable over a stained hardwood floor, but an oil based poly will still exhibit an amber hue that will continue to darken over time.

Does water based polyurethane dry clear?

A well-engineered, water based polyurethane will be equal in clarity to oil-based polyurethane. The main difference is usually color: water based polyurethanes are completely clear and (again, if well engineered) will not yellow over time.
