Created in the 1960s, urethane paint development took advantage of advancements in the technology of plastic. It became an alternative to regular enamel paint and offered increased durability and shine for use on outdoor furniture and automobiles. Urethane paint is not at all sensitive to ultraviolet rays, making it the perfect choice for any project that might see the sun on a regular basis, including your home. Mixing urethane paint to achieve the perfect color and thickness is easy.

Pick a Well-Ventilated Area

Using any kind of paint requires a well-ventilated space. Open windows and doors to allow for better air flow. This will not only help the paint fumes to leave your space, but will keep you from feeling lightheaded and confused.

Pick Your Colors

Urethane paint comes in approximately 50 standard colors. Brand names include Sherwin Williams, Dupont and PPG. Purchasing these brand name paints is an excellent idea because they all offer exact matching of colors. This will be important if you decide to touch up or completely repaint your space.

Mixing Your Paint

It is crucial to use a clean bucket when mixing your paint. Purchase an unused bucket at any paint or home improvement store. Strain your paint using a filter to eliminate any metallic clumps. Mix the colors of your choosing and use a paint stick to stir them together thoroughly.

Add Hardener and Reducer

Each brand of urethane paint has its own specific instructions for the addition of hardener and reducer. Pay close attention to the manufacturer's instructions for your individual paints. Most of the time you will combine 1 part hardener and 1 part reducer to 4 parts paint.

Paint Quickly

Keep in mind that urethane paints dry quickly. This is because they are activated by hardeners. Once your urethane paint is mixed, you have only a short amount of time to use it before it goes to waste. Generally urethane paint will last only 2 to 4 hours before it dries up. The positive aspect of urethane's quick drying time is that there is little waiting between coats.

Unused Paint

Remember to only mix enough paint that you are confident you can use up in an hour. This will save you money by reducing the amount of wasted, dried-up paint. Also note that you can never pour mixed paint back into the same bucket with unmixed paint. This will cause the entire bucket of unused paint to harden, and it will have to be thrown out.
