Makita 195236-5 4-1/2" - 5" Dust Extraction Surface Grinding Shroud

I rented a demo-hammer to remove tile and also used the hammer to remove a portion of thinset from a concrete floor. The hammer did not get the concrete smooth enough and still left raised areas of mortar. After lots of research I settled on using a grinder paired with a diamond pad. This dust shroud was perfect for the job. I hooked it to my Shop Vac and after getting a HEPA filter and fine particulate collection bag the process was much faster, yielded better results, and was less back breaking than the demo hammer. The only reason I gave four stars on suction power is because I did have to fill a little gap of the shroud by placing duct tape over it. Overall this was the way to go for my project and this shroud greatly reduced the amount of dust/debris in the air vs. what I experienced when I attempted the same thing with the demo hammer. I used the Makita GA-7021 along with Makita diamond pad and it had plenty of power, the diamond pad was expensive but well worth it. I also bought an adapter kit made by Rigid to connect the dust shroud to my Shop Vac because the output port of the shroud is smaller than the hose diameter of the vac.

This turned out to be far better than I expected. It turned a monster of a dirty job into something that was actually quite reasonable. Almost all of teh dust was captured except when I angled the grinder or ran over a very uneven spot. I found that I needed to clean the vacuum filter every square yard. I did that by removing the filter, inserting it into a bucket with a lid (actually a old kitty litter container), shaking the container, and then removing, dusting off and replacing the filter. That was I could clean the filter in the area that I was working in without creating a dust cloud.I do wish that I had read the instructions, if there were any. I eventually found that the unit worked best with the vacuum port pointing towards the point at which the cable entered the grinder. That way, cable and vacuum tube were aligned and easier to deal with. It also meant that I had maximum flexibility in getting into tight corners. I assume that there is a way to remove the section of the cover furthest away from the vacuum nozzle but I am still trying to work that out. It would be helpful to allow the grinder to get nearer to the wall.

A great add on to a Makita grinder.Easy to install. I use a diamond concrete grinding blade, attach a vacuum, and remove thinset. Works awesome. I've used it on concrete floors and well as plywood sub floors.Does a fantastic job removing thinset.Fast and as dust free as you can get.Only complaint, the brushes around the perimeter should be longer to better contain the dust. I add a piece of duct tape , folded so it doesn't stick to the floor. I tape it to the base to make a better seal and it's virtually dust free.Awesome results.

This product was exactly what I needed and exceeded my expectations. I purchased this product to fit onto my Makita 7" grinder with a cupped grinding wheel. Initially I purchased the diamabrush brand grinding wheel with the replaceable teeth, which did not work well at all for removing Thinset or epoxy paint from concrete. The diamabrush wheel skipped all over the place and left large marks in the concrete instead of a smooth finish. One note about this attachment is that you have to use a cupped disc, there is not enough clearance to use a flat disc. I read all the reviews on this dust shield and others, and was a little afraid of the fiber skirt falling off like others said but it never happened to me after 1000 sq ft of Thinset removal. This dust shield does have a small discharge outlet, but I found that using a hose from a smaller shopvac fit perfectly, and was able to duct tape the other end to my large shop vac which kept the dust down to a minimum. I did have to remove the small piece that allows for getting really close to cabinets and walls. When the small piece is removed it does not collect dust very well. Overall I'm very pleased with my purchase and I am impressed with the amount of dust control achieved with this product. Here are the pros and consPros: lightweight, durable composite material, removable outter piece that allows for close to wall grinding, dust skirt around the bottom, contoured inner grooves which channel the dust directly to the discharge outlet, easy installation.Cons: it is a bit pricey but ultimately worth it, small discharge outlet without accompaning adapter.Overall, this dust shield kept the dust down to a minimum and fit onto the Makita excellently. My main concern was silica from grinding the concrete. A few things to note for a do-it-yourselfer; it really pays to spend $20-$30 on bags for your shopvac if you want to really control the dust and prolong the life of your filters. If you own a shopvac brand, most of them will accept bags. If your shop vac has a small black plastic piece on the opposite side of where the hose is installed, you should be able to take that out and install a bag onto it and place that inside the shopvac. This not only prevents dust from clogging your filter, it also prevents dust from seeping outside of the seal where the motor unit sits on top of the bucket portion of the shop vac. It's well worth the money if you are concerned about keeping the dust down to a minimum. I still used 4mil plastic and painters tape to tarp off all the cabinets and rooms where there was no Thinset. Luckily we had nice warm weather and high winds that day so all the doors and windows were open to allow dust to migrate outside.The main reason I purchased the Makita grinder was because it had this attachment, and I figured it would probably be a good fit and it in fact did fit onto the grinder perfectly. I researched the universal ones and only read that the fit was marginal at best. I would highly recommend this for anyone removing Thinset or grinding down concrete. I opted for the 24 tooth rigid cupped grinding wheel, it was about $90 at Home Depot, comparable to here on Amazon. I didn't get from Amazon because I needed it that day when I discovered the flat disc wasn't compatable with this dust shield. I've attached a picture of the diamabrush disc that does not work with this dust shield attachment.I hope others find this review helpful! Good luck with your concrete grinding!!!

Makita did a great job with this shroud. First it SECURELY affixes onto the grinder by means of a tightening screw that is both philips and flat screwdriver compatible. It gives you the confidence to know that the shroud will not move while attaching a vacuum or extractor, while using the tool, or while moving around the work area. Second, it the suspension system on this shroud makes sure that your grinding cup is making firm and level contact with the work surface. Lastly, it is lightweight and edge friendly via the removable lip that exposes the grinding cup edge. Get yourself a makita hose that will attach to the suction outlet port and then attach that hose to your extractor hose. It will give you a bump in CFMs necessary to get all that dust into the vacuum where it belongs. This is actually my only complaint. The hose should come with the shroud.
