Can I pour this twice to raise 2"? Obviously using the proper primer in between pours.

Asked by: Shwa5
No, use regular cement mix to bring within 1/4 to 1/2 inch then top with this. Much more stable.

Can you install hardwood flooring using staples to secure wood? 

Asked by: Jolap
It is not recommended but I was successful in using under hardwood over a uneven plywood subfloor. The subfloor needs to be primed first, otherwise the moisture will be sucked out of the levelling mix, and it will not flow. I used a 10’ metal stud as a screed, and pulled it across the room to ensure smoothness as without screening, the leveller may leave slight ridges.  The leveller dries as cement, quite hard and brittle.  If the leveller is greater than 1/4”, the hardwood staples have difficulty penetrating. I had some which deflected and curved and required careful extraction. Also some flooring boards were damaged as a result.  I used roofing tar paper over the levelling compound and under the hardwood.  In the end I was able to successfully install 500 sq feet of acacia wood flooring. Installed for 3 years now without squeaks.

1) Is there a "curing" time when the surface has been completed? 2) Can this product be painted? Thank you.

Asked by: rbprop
Per the vendor: Drying time before installation of non-moisture-sensitive floor coverings at 70°F (21°C) at 1" (2.5 cm) thickness: 1 day. Drying time before installation of moisture-sensitive floor coverings at 70°F (21°C) at 1" (2.5 cm) thickness: 2-3 days. Curing time for max strength: 28 days. Limitations: Do not use as a final wear surface. Novoplan 2 Plus must be covered with a finished floor system or floor covering.

Can this be used to level old tile floor before engineered wood floor application? ( we just do not want to deal with old tile removal in our living space) Will it adhere to old tiles? thanks for your replies

Asked by: Jayhere123
it can be used for that purpose, only if the flooring you plan to install is not a nail down product. There are many other products that are less expensive and will achieve the same results.

Good day, How much cement does one bag make... by volume? I need to figure out how many 50 lb bags I'll need to make 1.25 cubic feet. (It's for a big circle in an old furnace room, 4' in diameter and not quite an inch deep.) Tks

How many bags will be needed to cover 450 square feet x 3/8 thick?

Asked by: RobertHuckey
Each bag mixes to about 1/2 cu. ft. I did a similar area of varying thinkness (leveling builder basement slab) and it took about 40 bags. Your specific math works out to about 28 bags, buy 32+ for good measure. Start where you want the highest slope to be if mixing by hand. No way to mix that many bags (without a 6-man team or renting a mixer) before the first pours start to set, so you will end up with a "more" level floor but don't count on a perfect level.

can this product be applied on a painted basement floor?

Asked by: Rmb1
My floor had a lacquer finish but the kids had also used it as a canvas over the years and painted many masterpieces on it with craft paint. We didnt have any issues using the leveller on top of it, in fact we told the grandkids to go to town painting what floor was left before we did level it all out. Just sad to see all those years of art work memories go.

Can this be used over old linoleum flooring?

Asked by: Jjham
Yes as long as the deflection is good on the floor. Make sure you use the primer

Mapei 22.7 kg Grey Self-Leveler Plus Underlayment is rated 4.0 out of 5 by 27.
Rated 5 out of 5 by from First leveller install- worked beautifully! Client bought to level her dipping concrete floor before rigid vinyl plank install. Primed floor. Sealed where needed. Mixed 3 bags all at once in 16.5 gallon bucket, to flatten/level 120"x46" area. Mixed it up, spread it quickly around and it flowed out on its own to a flat surface . 3 bags flowed perfectly to where the wood stairs started.

Rated 1 out of 5 by from Very inconsistent Usually buy a different product, but thought this would be okay seeing it was on sale. Did not level as I'm accustomed to with my other option buy a different product

Rated 5 out of 5 by from Great product! I used six bags of this product to level the floor in my daughter's Ensuite Bath. There was 1 inch difference between the highest and lowest corner of the room. This product is very easy to mix and apply. I used the lowest amount of water recommended per bag (4-3/4 liters) and it turned out to be enough for each of the six bags. The product poured well and also flowed very well to the lower sections. Turned out with a very even and bubble free surface. I recommend you do the mixing in a well ventilated area (outside preferably) as there is a lot of dust when emptying the bag. Also, throttle the bag with your hands when emptying to prevent/reduce splash. It can be messy. The bag is most easily opened from the bottom. The bottom of the bag is folded over itself and glued. After unfolding you can cut open at the end to give a longer clean section of bag for easier throttling and pouring. You can pour the entire bag with the water in your mixing pail before mixing and it will still mix easily and well with a drill and mixing paddle.

Rated 4 out of 5 by from Vérifiez le poids! Sinon, excellent produit. Je conseil fortement de vérifier le poids de chaque poche et d'ajuster l'eau en conséquence. Nous avions deux poches sur 7 avec approximativement 10% de mélange de plus! Ça fait une énorme différence de densité lorsque mélangé. Le mélange devrait être gris pâle et presque liquide (pensez couleur béton de trottoir). Pour la densité, ça devrait ressembler à du jus de tomate en canne. Si ça ressemble à du Ketchup et que c'est gris foncé, ajoutez un peu d'eau et continuez de mélanger.

Rated 5 out of 5 by from Great Product I actually usually buy this product and am very happy with the results. Recently I was in a place that didn't sell it and I purchased the DAP brand self-level and no matter what I did to it I couldn't get it to self-level properly. I went through 3 bags and none of them turned out. Definitely going to stock up on this product so that I have it when I need it in the future.

Rated 5 out of 5 by from Easier than I thought I was honestly afraid of this job, first time using self leveller. Installed a heated floor in my gazebo and needed to cover it with leveller before putting down vinyl planks. 150 sq. feet, 14 bags. Followed the mixing instructions with 5L of water exactly. Poured 1/2 inch thick, one pail every 10 minutes. Literally didn’t have to trowel or rake anything, just flowed perfectly. Heavy bags though, and heavier pails when mixed, very physical work when using multiple bags. Love it! Dried perfectly flat and level!

Rated 5 out of 5 by from Works well if you know how to use it It works well. It doesn't flow like water like people expect. No self-leveller does. You need to help the product to position itself and already have a rough idea of your low points before mixing the product. You need to feather the edges with a trowel and sponge. Product works best if you have at least a 1/4inch everywhere. It won't self-level in places where the depth is under 1/4". You can save on product by filling with pea gravel in deep areas.

Rated 4 out of 5 by from Follow directions, don't run out I bought 4 bags to cover 80 sq ft, quickly realized when pouring that it wouldn't be enough. Unfortunately I had to do 2 separate pours to cover my space (total 6 bags). No complaints about the product itself. It dries nicely. I ended up with a dip where the second pour met the first pour but this is what happens. 4 stars because it sets a little too quickly which made feathering difficult and by the time I got to the last bucket it was much thicker than when I mixed. I recommend adding the max water (COLD) it allows for best results.
