Acrylic Enamel Paint for Commercial Painting Decks

Acrylic Enamels for Wooden Decks

Last week, we explored the wonders of the ultraviolet spectrum. As we pointed out, although our bodies need UV light to make Vitamin D, in general UV light is bad news for outdoor structures. UV radiation fades colors and ages materials, especially wood. That’s why PennCoat recommends you use acrylic enamel paints instead of stains on wooden decks. The enamel is a much better defender against UV rays, and it has the additional benefit of not needing to be reapplied every other year.

Urethane Cement and Epoxy Flooring – Lancaster, Pennsylvania

Urethane Cement and Epoxy Flooring in Lancaster, PA

A local food manufacturer located in Lancaster, Pennsylvania was experiencing flooring issues in their dock room.  Because they deal with food, the room is subjected to routine cleaning with strong chemical cleaners.  Epoxy coats won’t tolerate this much moisture exposure.  So we had to offer a stronger flooring solution that could withstand the constant moisture, and hold up against the tough chemicals.  Additionally, because the floor is exposed to so much water, it is important that the floor offers slip resistance.  So, we proposed installing a urethane cement flooring system, that included a cementations aliphatic urethane top coat, and aluminum oxide broadcast.

Commercial Painting – UV Resistance

UV Protection — Aliphatic Urethane

One of the most important industrial and commercial painting features the PennCoat looks for in exterior topcoats is protection from the Sun’s powerful ultraviolet (UV) radiation. In today’s article, we’ll examine UV in some detail and then revisit the properties of aliphatic urethane topcoats and see how it stands up to UV rays.

Ultraviolet Light

UV light spans wavelengths from 400 to 10 nanometers, shorter than visible light wavelengths but longer than those for X-rays. Humans can’t see UV light, although some animals can. Because it vibrates at a higher frequency than does visible light, it carries more energy per photon and in high amounts can damage paints and people. UV takes its toll on exterior structures by making materials brittle and causing color to fade. In humans, it’s been linked to eye problems and skin cancer.

Commercial Painting – Using Mineral Spirits

Mineral Spirits

Last week we explored the properties and uses of denatured alcohol, an important solvent we use to clean surfaces and equipment for industrial and commercial painting. We also rely on mineral spirits for reducing paints and cleaning application tools after use. Although it has similar uses to those of denatured alcohol, mineral spirits have different physicochemical properties.


Mineral spirits, also known as “white spirit,” are petroleum-sourced mixtures of medium-chain aliphatic hydrocarbons ranging from 6 to 12 carbon atoms, but having a predominance of chains with 10 or more carbons as well as hexane (C6H14). Some mineral spirits also contain aromatic hydrocarbons like benzene. However, others, like Sherwin Williams R1K4 Mineral Spirits, are 100 percent aliphatic. The R1K4 product has a weight, volatile organic compound content and coating density of 6.42 pounds per gallon. The product’s flash point is 105°F and its specific gravity is 0.77. Other fun facts: R1K4 boils between 300°F and 395°F, is heavier than air and evaporates slower than does ether.

Commercial Painting Material – Denatured Alcohol

Denatured Alcohol

Alcohol is very important to us at PennCoat. Denatured alcohol, that is. It’s ethanol to which poison — often methanol — has been added to render it non-consumable. We use it every day to clean surfaces and equipment prior to use.


The main ingredient, ethanol, has the formula C2H6O, with two carbon atoms sharing a single bond — similar to ethane except one hydrogen has been replaced by a hydroxyl (OH) group. Ethanol is colorless liquid with a mild aroma. It is less dense than water (0.79 grams per cubic centimeter at 77°F), boils at 173.07°F and freezes below -173°F. It will auto-ignite if heated to 689°F. Its hydroxyl group can form a hydrogen bond, adding to its viscosity and lowering its volatility compared to propane, which weighs about the same as ethanol.
