Powder coating is a process by which a coating of pigment is applied to the surface of an item to create a layer of color that is brighter, thicker and much tougher than conventional paint.

powdercoating

Powder coating is a process by which a coating of pigment is applied to the surface of an item to create a layer of color that is brighter, thicker and much tougher than conventional paint. It involves the use of a dry powder which is sprayed onto the cleaned surface of the item in question. The powder is held on by means of an electrostatic charge imparted to it by the specialized spray gun that is used. This powder is made of a special thermoset polymer, which responds to heat. When the powder is baked, it reacts with other chemical groups in the powder polymer and increases the molecular weight and improves the performance properties of the material, creating a smooth and uniform layer of pigment. This process is used primarily on metals because of the high temperatures that the powder must be cured at. One will most commonly see power coats on processed aluminum goods and appliances as well as automobile and motorcycle parts.

sandblasting

Sandblasting is a process in which sand, glass beads or some other medium is shot at high speed through a machine across the surface of a hard material until it is sanded smooth. Sandblasting is often done to remove a previous finish on an item, to remove rust, or to prepare a surface to receive a new coat of paint. The kind of medium used to blast the surface depends on how difficult the removal is and how much impact the material can withstand.

How to Choose Sandblasting Media:

1. Start with a gentle medium if you are uncertain. If you are unsure how the material will withstand sandblasting it is best to choose the gentlest medium and work your way up. Walnut shells are one of less abrasive sandblasting media you can use and are completely biodegradable, so there are no concerns about environmental impact. Corn cob is also biodegradable and will not etch the material being blasted. Pumice is the softest of all the blasting media. It is often used to remove paint from soft wood.

2. Consider glass beads as a medium. Glass beads give a soft, bright finish that is more attractive than angular media. Glass beads can be recycled up to 30 times. Crushed glass grit made from 100 percent recycled bottle glass is also available.

3. Choose plastic beads for automotive sandblasting. Plastic beads are made out of acrylic, polyester, melamine and urea. They deliver a high stripping rate without damaging or warping the underlying material.

4. Use silicon carbide for toughest jobs. Silicon carbide is the hardest medium available for sandblasting. It allows for shorter blast times and lower cost overall than other media. It can be recycled more times than aluminum oxide or sand.

5. Pick steel grit or steel shot for special finishes. Though softer than aluminum oxide medium, steel grit leaves an etched surface that makes it easier for paints to adhere. Steel shot is used for peening operations to leave a smooth, polished finish. The shot can be used up to 3,000 times and produces minimal dust.

Sandblasting and cob blasting are important tools in log home restoration… but let’s face it. That’s not the real reason you have it done. It’s because the stain is faded or the finish is starting to peel or because no stain or sealer was ever applied and the logs are getting blackened or gray. In other words, your lovely old log home is looking sad and shabby. But there are even more important reasons to do this… logs need to breathe. And if there is too many layers of old finish on the logs, they can start to retain too much moisture and that’s the beginning of rot.

Sometimes, hidden problems are revealed when all the old finish is removed. This makes it obvious which damaged logs need to be repaired or replaced
