Question: Is this recommended to skimcoat over a sponge-painted wall? Actually the whole room!
Document: I have some experience working in the building trades, and I am an avid do-it-yourselfer. I bought this to skimcoat an entire room where wallpaper was removed from unprimed drywall. The removal process damaged and tore the drywall paper.If you have any experience with drywall joint compound at all I'm sure you will find that the Magic Trowel is a gimmick. It definitely does not perform as shown on its online videos. The joint compound needs to be watered down to an unacceptable consistency or else the magic trowel leaves too thick of a coating on the wall.
We used this to smooth out joint compound to remove textures from our wall. We needed a smooth wall to create a chalk board wall to write one. Worked like magic.
wish I had this tool before. have been renovating old house for some years now. this tool really makes mudding drywall easier. right now using it to skim coat walls with joint compound. doing excellent job.
this was exactly what i ordered. worked awesome with smoothing out lumps or skim coating. i would highly recommend this product
this tool worked great made from good quality rubber not flimsy or cheap feeling  we used it on my ceiling that was 340 sq feet and it worked great
significantly reduces sanding
We used this trowel to spread micro topping on our concrete floors. It was shipped fast, the quality is good and the price is right.
We just finished using the magic trowel to skim coat our plaster walls...amazing! Hardly any lines were left to knock down, which resulted in less sanding. We had little to no experience with mudding/troweling before starting this project and I am positive this trowel is the reason we didn't resort to Plan B (hiring an expert! ).
This trowel wasn't stiff enough to skim the mud off the ceiling that we were doing, and left little waves in the compound. If you are going to be skim-coating, just use a joint knife. We followed the directions and thinned out the mud before painting it on with a roller, but it worked much better to skim it off with a joint knife than to use this product.
This tool seems a bit pointless. I have some drywall experience and bought it to assist with a 1,950 sq foot drywall project I was doing. I was hoping it was going to help reduce sanding. In reality, it is not any better than a good finish taping knife and in some ways it is worse. You have to really thin the joint compound to get this to work and even then it leaves behind faint lines that have to be sanded. So, it really does not save time on sanding and you waste time thinning your joint compound.
Answer: yes
