Micro-Toppings - Rough Grade

Micro-Toppings - Rough Grade

A rough grade overlay with a fine consistency.

Concrete Coatings, Inc. Micro-Tek™ Micro-Toppings are commonly used on countertops or floors where an acid stain is desired, when the concrete itself is too abused to allow for a pristine surface. Rough Grade is available in natural, while Smooth Grade is available in white and gray. They are forgiving and easy to apply. Concrete Coatings, Inc. Micro-Tek™ Micro-Toppings require rough grade (RG) as a base coat and smooth grade (SG) as a top coat. These Micro-Toppings have just the right addition of polymer in the mix for their application—just add water. A separate polymer is not required.

5 Star ReviewExcellent Stain – I’ve used a number of different acid based concrete stains- Schofield, Kemiko, etc- and this performs just as well. Color and penetration were excellent. Would definitely recommend.

5 Star ReviewThis is by far the best stain I’ve used. The walnut color is gorgeous! Excellent customer service as well.

5 Star ReviewFountains and a concrete pad for over two years with beautiful and lasting results – I’ve used this stain on big concrete planters, fountains and a concrete pad for over two years with beautiful and lasting results. Easy to use and gives professional look.

5 Star ReviewGreat Product, used it on an Outdoor Patio – Came out great. Product leaves a nice color. Has been raining for 3 days straight since I stained and have not had a chance to seal it yet but seems to be holding color perfectly.

Do take note, I made my concrete have a “rock” design to it by adding features that made it look like stone, but also allowed the stain to sit there as it dried. Awesome for effect, you just have to be sure to scrub out any residue in any low areas as it will pool and shop-vac it out right away or it will just settle again.

5 Star ReviewGreat Product – Worked great and was easy to use. Applied to newer concrete-3 months old. I sprayed 2 coats but it colored so beautifully with the first application that I could have stopped after the first coat. Shipped quickly and was well packaged. There was a little spillage from the container, but It was sealed into a plastic bag so it wasn’t a problem. I will be purchasing this product again for our outside patio.

5 Star ReviewPerfect Outdoor Chessboard – Deep rich brown created from cheap gray 16″ square concrete pavers. I used this and the green one to make a chess board in my back yard. Oddly enough, large square pavers come in gray only—or a red with a brick pattern. So I couldn’t find 2 colors with the same plain look, and I’m glad I couldn’t because staining the plain gray concrete created a unique look that you would not be able to purchase even through special order. Plain gray concrete looks as cheap as it sounds, but now I’ve got a jade-walnut chessboard that cost me less than $4 per piece to make, including the stain.

Easy to use, and if you use zero water to wet the pavers before applying acid, you get a bubbling, hissing pool of acid, which of course is a bonus.

(wetting the surface first will create a more uniform color and will stretch the amount of coverage).

5 Star ReviewGreat stain, be liberal with application – This product worked very well and I really like the color. It did turn out a little more on the tan side in lighter applied areas, but ended up overall looking very nice.

As a first time acid stainer I learned a number of things. Prep is very important, take the time to do it right. Most importantly, is to make sure you are getting complete coverage when you are spraying the acid. You will note that there is some foaming immediately on contact which goes away quickly. This appears to be the time when the majority of the color transition takes place. As you brush in the liquid it still colors the concrete however not as deep as where the direct spray contact is made. I needed to be more generous with the initial spraying to make sure I had complete coverage. As a result, the appearance is a bit mottled and splotchy. Even with the incomplete coverage the floor looks significantly better than the bare concrete. Fortunately, I picked a room I built in my pole barn for my first try, but will be doing my basement and porch shortly.

5 Star ReviewThe floor turned out great! It took two coats of the acid stain to get the color we wanted and we love it. It’s hard to judge the true color of it until after it dries and you put a clear coat over it. The prep work is the hardest part but once you have a clean floor the application is easy. We used it in our basement pool-room and it took about 3 gallons to cover approx. 700 sq ft.

5 Star ReviewBought 2 gallons, only needed 1. I’m sure if I used the 2nd that it would have gotten darker but being that it’s outside in the sun, I didn’t want it darker. I LOVE the finished effect. Was scared when after I applied it, it turned neon orange, but after awhile it changed. PS if you do it in the sun it will turn quick!!!!!

5 Star ReviewGreat customer service by the actual manufacturer of the acid (not the seller). I called and spoke with the same person twice who gave me some great tips and ideas on how to get the best results. Be careful on how log you leave the stain on. We did a few test areas and when left on overnight the concreted turned almost black. At 1 hour my concrete reached a deep brown color. Not sure why but I’m happy with remote. Onto the sealer 2000!

Yes. You must put a base coat down prior to applying a smooth grade finish. Smooth micro-toppings are not designed for repair, spalling and uneven surfaces. We recommend the use of a single coat of RG micro-topping or the use of our G-100 and Duraset™ polymer to prior to applying the smooth grade topping.

1 ½ - 2 gallons of water for rough grade micro topping and 2 ½ gallons of water must be added to each bag of smooth micro topping. Once the water is added it is important to allow time for the polymers to become saturated. Wait 5-10 minutes; then remix and apply.

The first application can be applied with a squeegee or trowel at about 200 sq. ft. per bag of RG and SG micro toppings. Coverage with additional coats of smooth grade, usually applied with a trowel, increases due to a smoother surface with less voids etc. The second and subsequent coats are usually applied at 300-600 sq. ft.

Reason: If the stain is not fizzing it may signify an unsuccessful chemical reaction. Stain reacts with lime and other latents within concrete substrate. When a reaction does not occur it could signify that the concrete may be too old, washed out and/or chemical residue or oils may be interfering and preventing a proper reaction. If the stain is pooling on top of the substrate, a sealer or other curing agent may still be on the concrete preventing penetration.

Solution: Make sure any chemicals on the concrete are removed. If the concrete is old or washed out or you are dealing with a very tight power trowel, it may help to add no more than one cup of muriatic acid to one gallon of Chemical Stain Note: do not add muriatic acid to turquoise; doing so will cause an unfavorable result.
