Log Home Restoration - The Facts About Media Blasting


Media blasting is accepted as a means of removing coatings from most any surface. In log home restoration, it works well at removing old stains and finishes to prepare the wood for a new sealer. Like any tool, it has it's place, but sometimes is over used.

 

Media Blasting or Abrasive Blasting is the process of using compressed air to propel abrasive particles from a blast machine or blasting pot, through a hose and onto a surface at a high rate of speed in a way as to remove the existing coating and to be an effective cleaning treatment. Media Blasting for surface preparation removes unwanted coatings and leaves a clean surface ready for re-coating or other types of finishing.

Used in log home restoration, many contractors use it to remove any type of coating, oil or latex or just for cleaning to remove grayed out wood, dirt and mildew. Because of the nature of the process, it is more expensive than the basic chemical strip and requires some specialized equipment. An industrial type air compressor capable of producing at least 185 cubic feet per minute of air volume must be used. Some contractors own their own, but most rent one as needed. Also a special "blasting pot" designed to dispense crushed glass, baking soda and ground corn cob media is used. It is similar to a sand blaster, but modified to handle different media. Along with this special equipment, several thousand pounds of the media itself is needed. Three to four thousand pounds in not unusual.

Using Media Blasting for log home restoration does an excellent job of removing whatever is on the logs, however it is really best suited for the harder to remove water based and latex stains and paints. Chemical stripping on the other hand is best suited for oil based stains which is 75% of what is used on log homes in this area.

 

Media Blasting has it's advantages. The biggest being that it is a dry process. When the finish or coating is removed, the stain can be applied immediately. There is no waiting for the logs to dry as with chemical stripping, and no water to contend with inside the home from leaks. Also, the used media can be gathered up, sifted and reused. Once spent, it can be bagged and disposed of or, being biodegradable, it can be spread out and used as a soil amendment.

 

The actual blasting is a fairly fast process once everything is set up and staging and scaffolding is in place. Usually two people can handle the work; one operating the nozzle and one filling the hopper, adjusting air/media mixtures and watching that the machinery and hoses are in good working order and running properly.

 

There are also disadvantages with media blasting. There is more expense involved compared to chemical stripping due to the cost of the blasting pot, compressor rental, the media itself and the large amount that is needed. Also, walk boards, scaffolding and staging are needed where as with chemical stripping, ladders will usually suffice. And although a dry process, it does create massive amounts of heavy dust. This dust gets into anything and everything nearby.

During a log home restoration using chemical stripping, water can get inside the house from between the logs, around the corners and ceilings and other areas you might not expect. Anywhere the water can get in, so can media dust. Unlike water that will trickle through and can easily be wiped up, media dust on the other hand creeps in and can circulate throughout the house covering everything. If you have a good contractor, they will usually line the exterior walls with plastic which helps, but depending on how good of a seal is used, some dust will find it's way onto the kitchen table, cabinets, furniture and any other horizontal surfaces.

 

Another disadvantage is the profile left on the logs. This profile is created when the media hits the grain of the wood. The grain has soft and hard spots, and the softer spots will be removed deeper than the harder spots leaving a profile in the wood. This may or may not be an issue depending on the finish used, the number of coats applied and the look that is wanted. Depending on the wood species and the media blast operator, some grooves created in the logs may have to be sanded out. Be sure to discuss this with your contractor before your log home restoration begins so there will be no surprises after the coating is removed and there are logs left with a deep profile you did not expect to see.

Finally, maybe the biggest disadvantage of media blasting is the fact that it is being used when it may not be needed at all. Log home owners are paying for something they don't need. If your log home has the typical linseed oil based stain on it, media blasting is not needed. A chemical strip will work fine, cost less and much easier to clean up. Media blasting is needed only for latex stains and paints and only necessary on the toughest intact oil/alkyd based stains.

So when it is time to begin your log home restoration, do your homework. Make sure you are aware of what is needed and what is not. It not only could save you some time on the project, it could also save you money, money that could be used on other projects.

When You Don’t Need To Worry About Facts

By James Kwak


Masquerading behind an invocation to “wisdom” in the title, David Brooks today finds his false equivalence (see here for another example) by comparing the the two parties’ approaches to Medicare: the Democrats, he says, favor “top-down centralized planning” while the Republicans favor the “decentralized discovery process of the market.”


David Brooks swallowing Republican talking points whole is not worthy of note, so I’ll just point out one: he calls the Ryan Plan a “premium support plan,” despite the categorial denial by Henry Aaron, the creator of the premium support idea.* But it’s marginally more interesting to point out Brooks’s finely-honed rhetorical dishonesty.


The first example is characterizing this difference as a “basic philosophical choice” between centralized planning and the market, when it’s really the difference between having a government health insurance system and not having one. Brooks echoes the Republican characterization of the Independent Payment Advisory Board (Paul Ryan’s “fifteen-panel board“) as a centralized planning bureaucracy and expresses skepticism that it can work. But IPAB is supposed to do the same thing that every private insurance company is trying to do: figure out how to provide incentives that will improve care at lower cost. All large companies have centralized planning; that’s how they get things done. One problem with Medicare is that its centralized planning committee is called Congress, and hence Medicare payment rates are highly politicized. The alternative to IPAB is running Medicare poorly. Criticizing government experts as central planning is just a more reasonable-sounding way of saying that government programs shouldn’t have planning at all, which is transparently crazy.


The other alternative, Brooks would say, is not having Medicare at all. But the Obama administration didn’t choose IPAB because they wanted Soviet-style centralized planning; they chose it because it was the only pragmatic, responsible choice. Based on everything we know about Obama’s economic and domestic policy teams, it’s much more likely that, if they had a clean slate to draw on, they would have preferred managed competition — the exchanges, regulation, and subsidies that the ACA creates for the under-65 individual market — for the entire population. They stuck with Medicare because (a) it’s politically popular and (b) it’s already the lowest-cost part of our health care system. Dismantling Medicare would be like pouring gasoline on a fire: it would only exacerbate the problem of health care cost inflation, since Medicare pays lower reimbursement rates than the private sector.


The real choice is whether or not to have a government health insurance plan for the elderly. And in evaluating that choice, Brooks invents a whole new category of rhetorical subterfuge.


“The fact is, there is no dispositive empirical proof about which method is best — the centralized technocratic one or the decentralized market-based one. Politicians wave studies, but they’re really just reflecting their overall worldviews. Democrats have much greater faith in centralized expertise. Republicans (at least the most honest among them) believe that the world is too complicated, knowledge is too imperfect. They have much greater faith in the decentralized discovery process of the market.”


Why is this brilliant? Most ordinary pundits (those without space on the Times op-ed page) use the more common device of citing studies on both sides to show that there is support for both sides. But this is rookie league stuff. Brooks shows how it’s really done: just dismiss the entire attempt at empirical support with a wave of the hand, which lets you get back to “philosophy.” It’s much easier to know nothing than to know something.


But for this question, we don’t even need to go to the academic studies. We already have a health care system where people “select from a menu of insurance plans. Their consumer choices would drive a continual, bottom-up process of innovation. Providers could use local knowledge to meet specific circumstances.” It’s called the individual market, there are tens of millions of people in it, and it’s a complete failure. It leaves tens of millions of people uninsured, and to those who are insured, it delivers mediocre care at high costs. The only way you can ignore this fact is by pretending that facts don’t matter.


Then there’s this gem: “if 15 Washington-based experts really can save a system as vast as Medicare through a process of top-down control, then this will be the only realm of human endeavor where that sort of engineering actually works.” Um, David, there’s this country to north of us. It’s called Canada. They have a national health insurance system that covers everybody. And that system . . . Whom am I kidding? When you don’t have respect for facts, a few more aren’t going to change your mind.**


I’m not expecting the Times to fire David Brooks anytime soon, but after his enormous, embarrassing gaffe with the Ryan Plan, can’t his editor at least get him to stop writing about Medicare?


* The difference is who bears the overall risk of health care cost inflation. In a premium support system, you have a market mechanism to promote competition, but you keep beneficiaries whole by making sure that the subsidies, in the aggregate, continue to pay the same proportion of health care costs. In a voucher system, like Ryan’s, you decouple the value of the subsidies from the cost of health care, shifting risk from the government to the individual.

** For those of you weirdos who do like facts, Krugman has charts on costs and quality. In the latter, Canada doesn’t do so well (although still better than the U.S.) — but check out the U.K., where not only health insurance but health care delivery is public?
