The dispute with log home restoration companies continues to rage over the proper method of removing the old finish typically from the wood surfaces. You can try using a chemical to blast it off using water pressure, or crush corn cobs and blast it away with compressed air. These are the options.
A contractor who prefers chemical and the pressure washer will inform that cob blasting could damage and damage the timber ( pva application) as well as cause dust that is not wanted in and around the home, and is worth twice the amount of chemical stripping.
The company that prefers cob blasting will inform you that the pressure and chemical wash process can cause the wood to become “fuzzy” plus the pressure of the water will penetrate the walls and enter your home, creating mildew and water damage issues. Both are legitimate concerns, and while both are true in a certain degree, for homeowners the chemical or cob blasting appears to be an option that is feasible.
When properly done they can be used in a variety of ways and can be effective strategies to remove various finishes. If they are not used properly, both could cause extensive damage, not only to the logs but as well to trims made of metal glass, vinyl, as well as creating havoc inside of your log home due to excessive dust or water. Only the most knowledgeable professional should be able to utilize either method for the log house.
The majority of log homes today contain oil-based sealers and stains for these. In this situation chemical stripping is the preferred method to remove the coatings.
When it comes to chemical stripping, it’s about the process itself it’s not about the pressure! Chemical substances happen to be the device which is doing the hard work, not the strain washer. This strain washer that we decided to install is larger than the amount of water, not the pressure.
The process begins by mixing the weakest stripper with a weak solution, and then place them on top of the logs with a spray. It is allowed to “dwell” and get a certain period of time. This is an experiment to determine how the sealer reacts in response to strippers. If required, our business can alter the answer to an appropriate strength in order to eliminate the sealer but with the direction of minimizing “furring” to the wood. As per the sealer’s instructions, there is a certain amount of “furring” considering the wood is normal. It is simple to remove with the help of pads later on.
When chemical stripping is taking place takes place, my partner takes over the central part of a particular log home, looking for leaks. In addition, as of now it is inevitable that there will be leaks. We’ve never restored a wood home that didn’t leak up to a certain extent. Perhaps the most expensive log homes leak…It’s an impressive log! Leaks aren’t always bad. They are an excellent way to determine exactly where the house is the home of holes. If leaks are detected we will identify the location that the leak occurred in order for later inspection and resolve the issue through applying caulking or weather stripping the chinking process or any other method that is required to stop the leak, which creates a weather-proof house.
After stripping has been completed after stripping, it should be neutralized and given the proper time to dry prior to sealing. It usually takes between two and four days. However, the only method to know the exact timeframe is to conduct a test using an instrument for measuring moisture. A moisture content of 18% or less is required prior to ensuring that different types of finish are match.
To the unexperienced or too strong new chemical mix, it may not be able to “fur” the wood. But, it may make the wood soft until the point where it has to be replaced. If you apply too much pressure, it could not be able to completely “fur” the wood. However, you could gouge to extract wood, along with causing damage to other areas of the home such as siding, and windows. You need to find someone who is knowledgeable and chemical stripping is an effective method of removing older finishes.
