Can you pour self-leveling concrete over existing concrete?
You can pour self-leveling toppings or self-leveling overlays over concrete surfaces you didn’t think were salvageable, saving time and money. “It’s faster and easier than pouring new concrete,” says Paul Koury, president of Westcoat Specialty Coating Systems.
How do you prepare a concrete floor for self-leveling compound?
Quote from the video:
Quote from Youtube video: If any holes dips or cracks in the floor are deeper than the maximum thickness that the leveling compound can be applied to they will need to be filled with a suitable concrete repair compound.
Do you need to prime concrete before self levelling?
Self-leveling underlayments require the use of a primer prior to installation (like the TEC Multipurpose Primer). Failure to use product recommended primer may result in installation failure. Primer retains the moisture within the self-leveling underlayment to allow proper curing.
How much water do I mix with self-leveling concrete?
To ensure proper mixing, always add dry material to water when mixing, and never water to dry material. Use approximately 5 quarts (4.7 L) of clean potable water per 50 lb (22.6 kg) bag of either product. Adjust water as needed to achieve a self-leveling consistency.
How thick can you lay self-leveling compound?
Suitable for use on most common subfloors such as sand/cement screeds or concrete. It has high flow properties making it ideal for smoothing. It can be laid up to 6mm in depth.
Does self-leveling concrete level itself?
Self-leveling concrete is a cementitious mixture much like concrete. But unlike concrete, it flows easier and sets up much faster. The product is mixed with water, pumped or poured into place and spread evenly with a gauge rake. Once it’s spread out, it continues to flow evenly and levels itself out.
Will self-leveling compound crack?
A DIY self-levelling cement job might look good for a few months, maybe even a couple years. But if it’s not done properly, eventually it can start to crack.
Can you self level a floor in sections?
If you only need to level a room or section of flooring that requires less than 5mm in depth of screed then you can use a straight self-levelling compound, without the need to add sharp sand to the mix.
Is self levelling compound the same as screed?
Latex self levelling compound differs from the usual self screeds. The difference between ordinary screed and the latex self-levelling variety is that it contains a latex additive. Instead of using water to mix, this is replaced with latex. There is no need to add any additional water to this screed.
Do you need to seal self-levelling compound?
It’s always important to remember that levelling compounds are never suitable as a finished, wearing surface, and that they should always be covered.
Can you walk on self leveling compound?
Most concrete floor levelling compounds dry quickly, so they can be walked on after just 4 hours, drying fully after 24 hours. You can then install other types of flooring on top of concrete flooring after this stage.
How long before you can walk on self leveling compound?
Walk on time is typically 2 hours. Drying is dependent upon the absorbency of the subfloor, ambient temperature and humidity. The floor levelling compound must be left uncovered for a minimum of 24 hours before applying a floorcovering when applied at 2–5mm. Above this thickness, leave for 48 hours before covering.
Do I need to PVA before self-levelling?
There’s no need to use a PVA before you use a self levelling compound. However, it is advised that you clean and prime the surface before pouring over the cement mixture.
What happens if you add too much water to self-leveling concrete?
Too much water in a screed mix will mean that you are going to get increased shrinkage, and with it more risk of cracking, and you could be left with a weaker screed. A wet screed is going to make it hard to achieve a good finish, and you may end up with surface dusting due to high water contents.
