The controversy among log home restoration contractors’ rages on as to the correct way to remove old finishes typically from log surface. Try using a chemical and blast it off with water pressure or use crushed corn cob and blast it off with compressed air. Those are the choices.
The contractor that prefers chemicals along with a pressure washer will show you that cob blasting will pit the wood (pva manufactures), create much-unwanted dust inside and outside home and value twice as much as chemical stripping.
The contractor that favors cob blasting will tell you the pressure and chemical washing process are going to make the wood “fuzzy” plus the pressure of the water will shoot through the walls and get in your house causing water damage and mildew problems. Both of them are legitimate concerns, and although both statements are right to some extent, towards the homeowner, neither chemical nor cob blasting seems like a practical option.
However, when properly executed, the two of them have their place and are also efficient strategies for removing various kinds of finishes. When inadequately used, both can generate extensive damage not just to the logs, but also to metal trim, glass, vinyl along with causing havoc in the inside your log home from excessive dust and or water. Only the most experienced professional really should be advised to use either method using your log home.
Most log houses today still have oil-based stains and sealers for them. In this case, chemical stripping would be the preferred pattern of removing these coatings.
With chemical stripping, it’s all regarding the process, not the pressure! The chemical substance happens to be the tool that is performing the hard work, not the stress washer. The strain washer we chose to implement is so much more for the volume of water instead of the pressure.
We start by combining a weak solution of a stripper and put high them the logs by spray. It is permitted to “dwell” and get a predetermined amount of time. At this stage, it is the truth a test spot to see just how the sealer responds to the stripper. As needed, our company will adjust the answer to a beneficial strength to get efficiently rid of the sealer though in an approach concerning minimizing “furring” to the wood. According to the sealer, some “furring” considering the wood is to be expected. This truly is easy to remove using defeating pads later simultaneously.
While chemical stripping, my spouse covers the central section of a given log home checking for leaks. Moreover, now, there will inevitably be leaks. We’ve never restored a log home yet that doesn’t leak to a point. Maybe the costliest log homes leak…It’s quite a log! Leaks commonly are not necessarily bad. The fluids are known as an excellent indicator to pinpoint precisely where the house is home to holes. As the leaks are found, we are going to tag the spot where the leak occurred to come back later and address the issue by caulking, weather stripping, chinking or anything means is necessary to remedy the leak which makes the house weather tight.
As soon as the stripping is performed, it ought to be neutralized and allowed sufficient time to dry before sealing. This usually takes two to four days. However, the only way to be aware of with certainty will be to test along with a moisture meter. An 18% moisture content or lower it is necessary before various types finish is matched.
Into the inexperienced, too strong of a new chemical mix and you may not only “fur” the wood. However, it could soften the wood until the point it must be replaced. Too much pressure and you could also not exclusively “fur” the wood. Nevertheless, you can gouge to get wood, along with cause damage to other areas considering the home, namely siding, and windows. You have to have someone that knows what they’re doing, and chemical stripping is a viable solution to removing old finishes.
