Answer: 
I tried to use a normal plastic sprayer and it did not work well at all after a very short period. i am not sure what the issue was (maybe bubbles?). Anyway, I then just used a paintbrush to cover the area. It worked great. I a=have also heard of people using a sponge. As long as the liquid gets on the area, I believe it should work fine.

Hi,
Thank you for your question and interest in Concrobium products.
Pump sprayers are recommended to use with this product. You can also use a sponge or trigger spray bottle. We recommend scooping out any remaining foam after mixing prior to adding it to your sprayer or spray bottle as the foam can clog it.
We hope this answers your question. Feel free to contact us again if you require further Read More

Hi depawl. Thank you for your question and interest in Concrobium products. Typically the recommended order of application is to treat your space with Concrobium Mold Control first. When Concrobium Mold Control dries on the moldy surface it encapsulates and crushes the cells right down to the root structure of the mold spores. While you may be used to using bleach or bleach-based products that whiten the mold stain, this product contains no bleaches or whiteners so it may require some mechanical action to remove the stain. Concrobium Mold Control is a very effective cleaner, though in some circumstances you may find that the mold stains left on a surface are embedded and very difficult to scrub away. In this case, ensure that the treated surface is completely dry so that the mold spores have been eliminated. Use Concrobium Mold Stain Eraser as your second step to remove the tough embedded mold stains. Once the cleaning step is complete, it¹s recommended to leave a layer of Concrobium Mold Control on the surface to provide mold resistance. Read Less

I suppose they will both kill mold, but the stain eraser will eliminate any residual stain from the mold after it is killed.
I currently use the Mold Stain Eraser periodically and the Mold Control daily (on marble tile in a shower).
So, they can be used in any order. If I were you, I would probably use the Stain Eraser first and then later apply the Mold Control (the bottle says it creates a protective barrier against future growth). Read Less

If you are planning to re-stain the surface then this is not necessarily going to be an issue.

22.9 oz. Mold Stain Eraser is rated 4.0 out of 5 by 60.
Rated 5 out of 5 by from Great on cotton hammock I have a cotton Brazilian Hammock that I left in the rain several times and the mold went crazy. Black spots the size of a dime and minute speckles all through the fabric. I had to saturate the spots and then overspray the whole hammock. I felt in secure about the overspray getting into the fiber so after 15 minutes I misted the hammock with the hose. After 8 hours it appeared that I needed a second dose. A rain was expected within the hour so I saturated the spots again and did a overspray on the whole thing. The rain was light but lasted an hour or longer. The next day it was better than new. Even the minute speckles were gone. I wish I had saturated the ropes at the ends but this stuff is like liquid gold$$$. I did the same thing to white resin chairs w mildew and stain from mimosa flowers. Awesome! No scrubbing. The chairs needed to be well sprayed with the 1gallon pressure sprayer. This stuff is virtually $15 per gallon and I wish it was cheaper. But I will never scrub chairs or fabric with Clorox again.

Rated 5 out of 5 by from Works as advertised!!!!! I was skeptical because I tried bleach, vinegar, comet, even this brand's mold control spray. Scrubbed, scrubbed and SCRUBBED!!!!!! It would go away. Put this mixture on in the morning, 4 hours later, not too particularly impressed, but noticed change. 8 hours later, ALMOST ALL GONE!!!! Can't wait to see what it looks like in 24 hours. I just couldn't wait to write this review!!!

Mold Control, the Concrobium Mold Stain Eraser exceeds expectations! 24 hours prior spray on the Mold Control (which kills the mold) then the following day mix the Mold Stain Eraser in a bucket of water. Use a sponge , dip into water and wipe away. May take several times of repeating this but after all done ALL of my mold was gone. I used this in one bedroom and it worked so well I used it again in another bedroom. It also works well in the bathroom for tub and shower mildew. I encourage anyone who has a small (3ft or 4ft) patch of mold on your wall to use this product, you will be satisfied with its performance.

Rated 1 out of 5 by from Did not work We bought this product 2 days ago to use on the sheathing in our attic. Upon home inspection by our buyer it was discovered that we had mold staining on the sheathing in our attic. We lost 3 offers all at once. We used this product to try and get rid of the staining and treat the issue. Applied it within the correct time frame and temperature as per the instructions, and it did NOTHING! Looks the same as it did last week. Very disappointed and definitely not what we were hoping for after all we have been through. If you are trying

Rated 5 out of 5 by from Works like a dream on attic sheathing For my purposes, product worked to my satisfaction on the underside of attic sheathing that had developed a blackish discoloration [mold ?] to the wood after nearly 40 yrs. Easy to use - just read instructions. Basically, to a gallon of warm water add #1 tub, stir to dissolve, then to that, slowly add #2 tub stirring to dissolve. Ready to use. I used a pump up sprayer type device to apply. Within a short period of time (30 mins) you can see the blackness gone and the wood plywood was looking like new. One application, no muss, no fuss, no scrubbing, no further clean up. Could not be happier. Once whole project is finished, I will likely fog the whole area with Concrobium's Mold Control product. Before purchasing I checked out videos on line for my usage and was very hopeful that the product would work as I saw on videos for my application - for which I could not be any happier.

Rated 5 out of 5 by from Did wonders on my mom's deck! For mother’s day we decided to give my mom's backy deck a spring cleaning and chose Concrobium Mold Stain Eraser. I wasn't sure how effective it would be because the solution seemed really harmless when we mixed it up and applied it to the deck. It was super easy and started working right away. After rinsing it off we were absolutely amazed and delighted at what a great job it did. The deck was almost back in its original condition after several years without cleaning. My mom was SO pleased and relieved to know that her precious plants and flowers weren't hurt in by the product. Will definitely use this product again.

This product was used on a small patch of fungus under my house that had stained the concrete blocks. It worked as described. There was a small area that needed a second application. The directions were easy to follow. It did not have a bad/strong smell and I would buy the product again.
