Choose a self-levelling compound by matching the substrate, required thickness, floor covering and installation programme. Bag price alone does not show the quantity needed or whether a product is suitable. Confirm the system and site conditions before ordering or scheduling the next trade.
What is LEVELMAX ProFlow?
LEVELMAX ProFlow is a cement-based self-levelling compound supplied in 20kg bags. Its published application range is 1–40mm per coat. It prepares a base for a suitable floor covering and is not an exposed final wearing surface.
Start with the ProFlow product page and the current technical and safety data sheets. Product information should be matched to the actual bag and document version used on site.
Check these five items before choosing a floor leveller
-
Substrate: Identify the base, its condition, contamination, movement and moisture. A levelling layer cannot make an unsuitable substrate suitable on its own.
-
Thickness: Survey the floor and estimate the average build-up. The deepest low point is not necessarily the average thickness across the room.
-
Floor covering: Confirm whether the next layer is timber, vinyl, carpet or tiles, and check that product manufacturer's requirements.
-
Preparation and primer: Choose a documented, compatible preparation system. Do not assume every primer can be used on every substrate or under every compound.
-
Installation programme: Separate working time, light foot traffic and readiness for subsequent bonding. They describe different stages.
How many bags of ProFlow will I need?
The published ProFlow TDS gives an indicative consumption of 1.65kg per m² per mm of thickness. Divide the estimated mass by 20kg and round up to whole bags. Add a project-specific allowance for surface profile and wastage.
Example: 100m² at an average thickness of 5mm requires approximately 825kg before allowance. That is 42 whole 20kg bags. With an illustrative 10% allowance, the estimate becomes 907.5kg, or 46 bags. The 10% allowance is an example, not a manufacturer-specified requirement.

Use the floor preparation system guide to plan an enquiry. Confirm quantities against the actual floor survey before purchasing.
When can timber flooring be installed?
Do not treat walk-on time as permission to install a floor covering. Application thickness, substrate moisture, temperature, humidity and the next flooring system all affect readiness. Obtain the current written requirements for your project before scheduling timber installation.
For ProFlow, contact the LEVELMAX technical team to confirm the waiting time and conditions for subsequent bonding. A fixed time without those conditions is not a reliable installation instruction.
What matters on Australian sites?
Record the actual site conditions rather than relying on the season or postcode. Hot weather can shorten working time; cooler conditions can change the installation programme. Follow the product's stated application limits and confirm any underfloor-heating procedure with the relevant manufacturers.
For apartment projects, assess the complete floor build-up against the project's acoustic requirements. A levelling compound or adhesive name on its own does not establish that an apartment floor meets its required acoustic performance.
Compare products on the same basis
When comparing options, use current manufacturer documents for the exact product sold in Australia. Check pack size, consumption at the same thickness, permitted substrates, preparation, application limits and conditions for the next floor covering. Do not transfer a similarly named product's specifications, certifications or warranty to another brand.
For a project quote, send the floor area, average thickness, substrate, planned floor covering, postcode and required date to LEVELMAX trade support.
