In Part 1 of this series, we looked closely at the need for chlorinating and cleaning your home before painting. The guidelines and methods outlined for the reason that article were mainly focused on identifying mildew and how to effectively eliminate the mildew spore before pressure cleaning so https://giphy.com/channel/powerwashingnj as to prevent it from immediately returning and leading to problems with the brand new coating.
These procedures were fond of homes that are going to be repainted. The techniques and the methods for chlorinating a hardwood surface, such as wood siding are much different for many reasons. Understanding why refinished wood should be cleaned differently will make perfect feeling by enough time you finish this article.
As you might recall partly 1, anytime a surface area has been recoated with a crystal clear finish or any type of semi-transparent stain, the finished item will only look good if the substrate looked good before it was coated. The reasons for this should be obvious, because a obvious or semi-transparent finish is seen through.
With a wood or masonry surface that's being recoated with a standard paint, less care is needed when cleaning since it will be covered. A scorched earth approach could be applied to the eliminating of mildew when you repaint, but it will not work when coping with the various sealers and spots typically used for hardwood.
HOW EXACTLY TO Properly Chlorinate Wood Siding
Given that we understand the reason why for treating these hardwood surfaces differently, let's go through the correct method to use to ensure that your finished product and the end result looks professionally done. Timber siding or any external wood surfaces will typically have a range of visible stains and flaws that will range in varying levels of severity. The most typical will be mold and mildew, gray weathered patinas, and corrosion or rust staining from fasteners.
Some of these stains, just can't be removed 100% of the time. The success or failure in removing these flaws would depend on the length of time because it was last refinished and various other factors. A flawless end is not always possible, but you can certainly make it look far better then it did, and generally you may make it look fabulous. My suggestion is to clean and rinse a small sample section first. Let it dry and then seal or stain it with the merchandise you intend to use. Then you can make a determination concerning whether it's acceptable or not.
I'll list the key points for chlorinating and cleaning timber below with explanations and descriptions for each. Again, none of the is rocket research, and none of these methods are tough to do... but they are essential nonetheless, and come from years of experience.
High Pressure Versus Low Pressure
High pressure washing is never a good thing with regards to wood. It's Fine to still use a power washer, however the machine ought to be used more as a heavy duty, glorified power rinse rather than a cutting device. The normal technique of bearing down on solid wood with a power washer can be an improper technique and should be avoided because it can damage the wood and perhaps force water into areas that cannot properly drain. The correct method is to use low pressure methods for the use of bleach and for the rinsing procedure.
Power Washer versus Pump-Up Sprayer
For real wood siding or overhangs that seem to be in good form with hardly any mildew or weathered staining, a pressure washer utilizing a pick-up tube for the bleach solution will work just fine generally. However, if the siding is definitely noticeably flawed with plenty of mildew, a pump-up sprayer can do the best work. As I mentioned in Part 1, with all the pressure washer's pick-up tube for drawing the bleach from the bucket, it will be diluted at least 10 to 1 1 by enough time it comes out of the tip. Using a pump-up backyard sprayer allows you to control the strength of the solution.
Normally, I would recommend a 50-50 mix of drinking water with store bought bleach and a little amount of TSP substitute for detergent with all the backyard sprayer. if the timber is definitely in really bad shape, or if the 50-50 mix is not getting rid of the mildew within 20 minutes, change to full power bleach. The TSP alternative can be bought at any paint store and at most hardware stores. Painters have been using it for a long time and it's very inexpensive. Just adhere to the directions on the box and you will be fine.
Bottom To Top, Bottom level To Top, Bottom To Top!
Applying the bleach remedy from bottom to top is http://query.nytimes.com/search/sitesearch/?action=click&contentCollection®ion=TopBar&WT.nav=searchWidget&module=SearchSubmit&pgtype=Homepage#/New Jersey the most important, no compromise rule that needs to be followed in the event that you intend to finish your wood siding with a clear semi-transparent complete. When you apply the bleach answer from bottom to best, you eliminate the risk of streaking since the bleach solution is only going to be able to drip and run onto a previously wetted out surface.
If you were to apply the bleach from the very best down, it'll be running and dripping onto a dry surface and can probably streak and stain the real wood, leaving very hard or impossible flaws to remove. I can't stress enough the importance of this simple but extremely important approach, and easily could add anything compared to that it would be to go part to corner as well. So, to re-cap.... it's bottom to best and corner to corner!
Putting It All Together

In Part 3 of this series, I'll show you the best way to remove color from masonry surfaces and more tips about how to complete the energy washing after the chlorinating step is certainly complete.
