Polycrylic Vs Polyurethane

Traditional solvent-based mixes have a high VOC content, making them unattractive choices for health reasons. The newer water-based lacquers lack the luster that lacquer is known for. Nitrocellulose is also also highly flammable, severely limiting its potential uses. In terms of individual bases, some come with their own perks. For example, acrylic lacquer is more durable and less likely to yellow. Meanwhile, water-based is VOC-free and dries faster, plus it’s the most cost-effective.

Water-based polyurethanes do not atomize easily, despite their thinner consistency. This is especially so when the polyurethane itself is cold. We suggest using an air-assisted or airless spray gun in order to achieve the best atomization for your water-based polyurethane. You can also thin the water-based solution in order to improve atomization. Once you have finished using your spray can polyurethane, you must allow the finish to dry completely.

Water-based polyurethane finishes are a combination of an acrylic resin with polyurethane. These coatings are not as strong as the oil-based version, but they do offer a number of favorable properties.

I used an oil-based poly to seal this wall-mounted DIY wine bar. The temperature and humidity levels can affect the drying times. This fast-drying polyurethane can be recoated after 3-4 hours. It needs another 24 hours before it’s ready for “light use”.
