Why is Priming Before Levelling Non-Negotiable on Sydney Construction Projects?

Priming before levelling is the process of sealing and conditioning a concrete substrate so a levelling compound can chemically bond to it. Without primer, self-levelling products can delaminate, crack, or fail. On NSW projects, priming is a prerequisite for performance warranties and compliance-aligned installation.

What is priming before levelling? Priming before levelling is a preparatory step where a purpose-designed bonding agent is applied to a concrete or cementitious substrate before any levelling compound is poured. The primer penetrates surface pores, binds residual dust, and creates a controlled surface tension that allows levelling products to cure correctly.

In practical terms, primer performs three critical functions:

It stabilises porous or dusty concrete surfaces It prevents moisture shock between slab and levelling compound It enables chemical adhesion rather than surface friction alone On Sydney construction and renovation sites, skipping this step is one of the most common causes of premature levelling failure.

How does this impact Sydney property owners or businesses? For property owners, developers, and asset managers in Sydney, improper substrate preparation introduces latent risk. Levelling compounds that debond often fail silently at first, then release suddenly under load, moisture variation, or vibration.

This can result in:

Costly remediation after fit-out completion Disruption to tenants or business operations Insurance disputes where installation steps cannot be verified Loss of manufacturer warranties In commercial and strata environments, these failures are not cosmetic issues. They are operational and legal liabilities.

Why is this important for NSW projects or compliance? NSW construction and renovation works operate within a compliance-heavy framework. Product manufacturers, certifiers, and insurers all require documented adherence to installation systems.

Priming is explicitly referenced in technical data sheets for levelling products used across NSW. Pouring directly onto an unprimed slab typically voids:

Product warranties Installer guarantees Insurance coverage for consequential damage From a governance perspective, this creates a verification gap. Elyment addresses this risk through operational documentation, photographic records, and workflow controls integrated into its delivery systems.

Relevant guidance aligns with standards referenced by NSW Fair Trading and material performance research published by institutions such as the University of New South Wales.

What does this typically cost or affect in Sydney? Item: Primer material

Indicative Impact: Low Notes for Sydney Projects: Minor cost relative to remediation Item: Application time

Indicative Impact: 30–90 minutes Notes for Sydney Projects: Often same-day with levelling Item: Failure remediation

Indicative Impact: High Notes for Sydney Projects: Can exceed original works multiple times Item: Operational disruption

Indicative Impact: Severe Notes for Sydney Projects: Particularly in commercial properties From a cost-risk perspective, priming is one of the highest return steps in any levelling workflow.

What are the risks or benefits? Risks of skipping primer:

Levelling compound popping or shearing from the slab Cracking under point loads Moisture-related bubbling or hollow spots Non-compliance with manufacturer systems Benefits of correct priming:

Predictable curing behaviour Long-term substrate stability Warranty alignment Lower lifecycle maintenance risk In regulated environments, the benefit is not just technical. It is evidentiary.
