Wildcat grinder dust shroud9/9/2023 Came out *really* great, worked perfectly for my purposes, and yielded a naked concrete surface for installing the 18-inch porcelain tiles.Īdded a few screw eyes to the plywood, and used cable ties to snug the handles of the grinder to the "dust shroud". About $15 worth of big-box plumbing bits: 2 gallon bucket, shower drain, and coupling, which I hacked together as a bespoke grinder shroud. I didn't want to spend $$ on a "fits all brands" shroud, and the DeWalt -specific one for my grinder was over $100, so I decided to DIY. DeWalt grinder, and a 7 inch "DiamaBrush" grinder, specifically for removing coatings from concrete, for something like $70. I caught a few good tools deals for the project: < $100 for a 7 inch. I investigated various methods, including chemical (toxic and otherwise), and renting a floor grinder, with a daily cost approaching $500 (and unclear whether I could get it done in one day). The existing linoleum tiles came up quickly, but the kryptonite mastic (at least 40 years old, perhaps even older) needed to be removed from the concrete slab. It’s the 7″ Makita grinder dust shroud.Massive DIY gas fireplace project included (as just one of the sub-projects) ~200 sq. The price is $51.99, and you’ll be happy you did. Check it out from your local Home Depot or from. So, spending $50 for better health and a cleaner shop and job site should be a no-brainer. We don’t even scoff at spending $150-300 on a new power tool. If you think that spending $50 on a dust shroud is too expensive, this is quite silly. With the shroud in place, we saw virtually see no dust, until we ran off the edge and exposed the bottom of the concrete grinding wheel. Using the grinder shroudless covered me and the surrounding area with dust in a few seconds. Testing on our new concrete pad really told the story. Along with the grinder and shroud, we used the Makita Xtrac Vac to suck the concrete dust from the shroud. This resembles the tool we used in the Makita Polisher 7-inch 9237C Video Review, but looking deeper unveils a much different beast. We tested our dust shroud with the Makita GA7011C 7″ grinder. Depending on the work you do, the typical shop vac may not comply. You need a qualified dust extractor as well. Of course, you can just install a dust shroud on your grinder and call it done. The Makita dust shroud not only protects your lungs and body from exposure, but it also keeps the job site tidy. This stuff is bad for your lungs and gets all over everything, hence it creates a real mess. Grinding and sanding concrete can cause nasty dust that contains the aforementioned crystalline silica. Regardless of OSHA’s rule, I won’t grind concrete again without a shroud and dust extraction.Ĭheck out the line of OSHA compliant dust extractors from over at Pro Tool Reviews. For about $50, the Makita grinder dust shroud, along with a dust extractor (or shop vac), will all but eliminate the dust from grinding concrete. I’ll let you do the searching on the OSHA details, and we’ll talk about the tools. With the new OSHA Crystalline Silica mandate, you may be required to extract any dust you are making. Using a dust extractor may not be a choice anymore. Using the Makita grinder dust shroud in conjunction with a dust extractor is not only healthier, it also eliminates the cleanup from all the dust.
