Can you put a second coat of self-leveling compound?
Hi, yes you can put a second coat on wait till floor is completly dry then mix a uni-bond solution 80 parts water to 20 parts uni-bond apply this to the floor and lay second coat before this dries the thinnner the coat the more level it will be.
Can you pour multiple layers of self-leveling concrete?
Yes, you can use multiple layers on top of one another. Just make sure the first layer is fully dry and hard before adding a second. Also use a primer just like you would any other concrete floor unless your new leveler has primer built in.
How thick can quikrete resurfacer be applied?
One 40 lb (18.1 kg) bag of Re-Cap® Concrete Resurfacer will cover approximately 16 ft2 (1.5 m2) of surface at a thickness of 1/4 in (6.3 mm) or approximately 65 ft2 (6.0 m2) per bag when applied at the 1/16 in (1.6 mm) thickness with a broom or squeegee.
How long does it take for self-leveling compound to dry?
Protect your freshly poured underlayment: All self-leveling underlayments should be protected from direct air movement (drafts) during the initial curing process (2-6 hours) as they may cure prematurely which leads to cracking.
Can you layer Levelling compound?
Can you lay self levelling compound in layers? Yes, as long as you clean, prime and abrade the first layer.
How thick can you go with self leveler?
QUIKRETE® Self-Leveling Floor Resurfacer (No. 1249-50) can be installed from 5/8 inch (16 mm) thick to a feather edge. For areas deeper than 5/8 inch (16 mm), apply QUIKRETE® Self-Leveling Floor Resurfacer (No. 1249-50) in layers no greater than 5/8 inch (16 mm) each.
What happens if you add too much water to self leveling concrete?
When excess water is used in cement-based mortars, grouts, levelers or patches, it increases spacing between the molecules of the mixture and stops the fingers from interlocking tightly, weakening the cement. This can lead to shrinkage cracks, along with decreased flexural and tensile strengths.
How long does floor leveler need to set?
Do not walk on the resurfaced floor until it has fully gained sufficient strength. This is approximately 1 to 2 days for the Normal Set product or 2 to 4 hours for the Fast Set product, depending on surrounding conditions. No special curing steps are required.
Do you need to prime concrete before self-levelling?
The floor needs to be primed before adding the floor leveler and you’ll want the primer to soak into the floor, not the dirt and dust sitting on top of it.
Do you have to seal self-leveling concrete?
Once dry, a self-leveling overlay can be covered with a traditional flooring material, like carpet, tile, hardwood or laminate; or it can be sealed, and left exposed, to use as a wear surface, because its cement composition gives it a hardness and durability meeting or exceeding that of normal concrete.
What consistency should self-leveling compound be?
Quote from the video:
Quote from Youtube video: Keep mixing until you achieve a runny pancake batter consistency.
Is self-leveling concrete waterproof?
HLM 5000 SELF LEVELING grade is a one-component, moisture-curing, bitumen-modified polyurethane elastomeric waterproofing membrane for exterior below-grade or between-slab applications. Used for both vertical and horizontal applications. Product can be applied over Green Concrete (see data sheet).
Can you waterproof over self Levelling compound?
Note: Self-levelling cements are not suitable for application over waterproofing membranes although they may be applied to prepared concrete substrates as bonded toppings and subsequently protected by an applied membrane.
What can I use instead of self leveling compound?
The cheapest way to level a concrete floor is to use a specialized sand mix. This sand mix is 90% more affordable than self-leveling concrete while producing similar results. To do this, you will spread the sand mix across the top, spray it with water, and then let it dry.
Can you self level over membrane?
Nicole, I wouldn’t put a self levelling compound directly on top of a DPM as the compound is only laid in a very thin layer and as there will be no adhesion it will crack up as soon as any pressure is applied.
Can you self level over Tanking Slurry?
When it comes to a finish, tanking coatings should always be protected so never left exposed. You should apply a floor screed (this can be self-leveling). You can then tile or install other floor finishes on top of the screed if you wish.
Can you screed over liquid DPM?
Indeed, a liquid DPM is OK. You can use it depending on the screed. You can actually sand scatter the liquid DPM. When the liquid DPM is still wet, you sprinkle over with some kiln-dried sand onto the surface.
