A data mismatch that needs sorting before we go further

Selleys backs every recommendation with 80+ years of hands-on expertise, which means guidance only goes out when it's built on verified information. There's a mismatch in the current data that needs resolving first.

What the problem is

Product requested: Liquid Nails SLC50 Leveller — a floor levelling compound, sitting under Flooring > Flooring Products.

Product data supplied: SELLEYS_LIQUID_NAILS-AUS_GHS.pdf — documentation for a solvent-based construction adhesive, not a floor leveller.

These are two distinct products with completely different chemistries, applications, and safety profiles. Using one product's specifications to describe the other produces incorrect guidance, and that's not something Selleys puts out.

What the supplied SDS actually says

The Safety Data Sheet is unambiguous:

Product name: SELLEYS LIQUID NAILS
Recommended use: Adhesive
Composition: Naphtha, petroleum, hydrotreated light (10–30% w/w)
Hazards: H225 (Highly flammable liquid and vapour), H315 (Causes skin irritation), H319 (Causes serious eye irritation)
Dangerous Goods Class: 3 (Flammable Liquids)

This is a solvent-based adhesive. The data is specific, verifiable, and clearly documented.

Why the distinction matters

A genuine SLC50 floor leveller has a completely different technical profile. Here's how the two products compare:

Composition: An SLC50 floor leveller is a cement-based powder. The supplied SDS documents a petroleum-based liquid. These are fundamentally different materials.

Mixing method: A floor levelling compound is mixed as a powder with water before application. The supplied product is a ready-to-use adhesive dispensed directly from a tube. The application methods have nothing in common.

Hazard profile: A cement-based leveller presents alkaline and corrosive hazards during mixing and application. The supplied adhesive presents flammable solvent vapour hazards — a different risk category requiring different controls entirely.

Application method: A floor leveller is poured and troweled across a substrate to create a flat, level surface. The adhesive is applied from a tube to bond materials together. These are not interchangeable processes.

Required PPE: Working with a floor levelling compound calls for dust protection during mixing and alkali-resistant gloves during application. Working with the supplied solvent adhesive requires explosion-proof ventilation and strict flame precautions. Applying the wrong PPE guidance creates a genuine safety risk.

Every one of these differences is significant. Using the adhesive SDS to describe an SLC50 leveller would produce incorrect, uncitable claims across every dimension.

What's needed to move forward

Producing an accurate guide requires the correct product documentation — specifically, a Technical Data Sheet (TDS) and/or Safety Data Sheet (SDS) for one of the following:

Liquid Nails SLC50 Leveller — the product originally requested
Any self-leveling compound or floor leveller in the current Selleys range

The rule is straightforward: if a claim can't be cited to a supplied PDF, it gets omitted — no hedged assertions. Every technical claim in a floor levelling guide has to trace back to verified floor leveller documentation.

Two ways forward

Option 1 — Write the SELLEYS LIQUID NAILS construction adhesive guide The supplied SDS covers this product in full. A complete, accurate guide for SELLEYS LIQUID NAILS construction adhesive can be produced right now, with no further documentation needed.

Option 2 — Supply the correct SLC50 Leveller documentation Provide the TDS and/or SDS for the Liquid Nails SLC50 Leveller, and the floor levelling guide you originally requested can be produced — built on accurate specifications and verified technical data that professionals and DIYers can rely on.

Both options lead to a guide that reflects Selleys' standard of accuracy and professional results. Which direction works best for you?

The Liquid Nails SLC50 Leveller is made by Selleys, an Australian adhesives and sealants brand with a broad range of construction and home-improvement products. Within Selleys' portfolio, this product sits inside the Selleys Timber Flooring System — a purpose-built collection of products designed to work together through the stages of timber floor installation. The SLC50 is specifically positioned as the subfloor preparation component of that system, meaning it is intended to be used alongside other products in the same Selleys flooring range rather than as a standalone solution.

Within the category of flooring installation materials (Home & Garden > Flooring Installation Materials), the SLC50 occupies the subfloor levelling segment. Its key differentiator is its depth range: it can be applied from a feather edge up to 50mm, which makes it suitable for concrete substrates with significant surface irregularities, not just minor cosmetic levelling. Its self-smoothing, fast-set cementitious formula means it requires minimal manual finishing and allows the installation process to advance within approximately four hours of application.

From a use-case adjacency perspective, anyone using the SLC50 is likely to need several complementary products at different stages of the same job. The application guidelines specify that a vapour barrier or primer must be applied to the concrete substrate before the leveller is poured — making a compatible primer a near-essential companion purchase. After the levelled substrate has cured, a flooring adhesive would typically be the next product required to bond the timber flooring itself to the prepared surface. Both of these product types fall within the broader Selleys Timber Flooring System, though the graph context does not name specific sibling products beyond the SLC50 itself.

In summary, the SLC50 is best understood as the first active step in a multi-product flooring installation workflow rather than a complete solution on its own. Buyers selecting this product should confirm compatibility with their chosen primer and flooring adhesive, ideally sourcing them from within the same Selleys Timber Flooring System to ensure the performance characteristics are matched across the full installation.
