Flooring Top Coats: A Specification Guide

For architects and specifiers, flooring top coats are a critical component of system performance, not a cosmetic add-on. The selected top coat directly influences how a floor performs under traffic, how it responds to UV exposure, how it is cleaned and maintained, and how closely it aligns with compliance and project documentation. 

All Purpose Coatings manufactures a comprehensive range of Australian Made flooring top coats, each formulated to suit specific environments, access constraints, and performance requirements. While multiple products may appear interchangeable, their differences in curing profile, VOC content, UV stability, and regulatory alignment make them suitable for very different project types. 

This guide outlines the practical differences between APC flooring top coats, with a focus on where each is best specified, what benefits they bring to a project, and what considerations should be addressed during documentation.

What the Flooring Top Coat Does

From a specification perspective, the flooring top coat governs the final interaction between the built environment and its users. It determines slip characteristics, surface clarity, resistance to staining and chemicals, and the impact of sunlight or artificial lighting over time. 

In many commercial and public projects, the top coat also influences return-to-service timelines, which can affect construction sequencing and occupancy planning. Selecting the correct top coat ensures the broader coating system performs as intended under real-world conditions. 

SPARTA60® Polyaspartic Flooring Top Coat

SPARTA60® is a polyaspartic flooring top coat designed for projects where rapid cure times must be balanced with finish control and UV stability. Its formulation allows for both internal and external use, making it suitable for mixed-use developments where continuity across spaces is desirable. 

Architects and specifiers frequently nominate SPARTA60® for residential garages, commercial interiors, hospitality venues, and Cut & Coat applications. The product supports high-gloss finishes with strong visual clarity, aligning well with decorative flake systems and polished concrete-style aesthetics. 

SPARTA60® provides flexibility for time-constrained projects. Slip resistance should be addressed at the system level where required, particularly in areas exposed to moisture. 

SPARTA SHIELD® Polyaspartic Flooring Top Coat

SPARTA SHIELD® is formulated specifically for exterior flooring applications exposed to direct sunlight and weather. Its UV stability and fast curing profile make it well-suited to environments where external performance is the primary concern. 

Specifiers commonly select SPARTA SHIELD® for driveways, car parks, pool surrounds, pathways, and outdoor commercial spaces. The product supports fast return to service, which can be critical for external works or access to sensitive sites. 

Given its rapid cure characteristics, application planning is essential. SPARTA SHIELD® is not designed for wet-on-wet application, and this should be reflected in construction sequencing and contractor coordination. 

SPARTA GUARD® Polyaspartic Flooring Top Coat

SPARTA GUARD® has been developed for projects where compliance, environmental considerations and long-term performance are non-negotiable. It's APAS approval positions this product as a reliable option for government, education, and publicly funded projects. 

This flooring top coat is commonly specified in schools, universities, healthcare facilities, and large format commercial spaces. Its ability to be used internally and externally supports consistent finishes across varied environments, while compatibility with Ultra Flake® and Hyper Flake® systems allows aesthetic intent to be maintained throughout a project. 

While cure times are more controlled than rapid polyaspartics, this supports application quality across large floor areas and complex sites, a consideration often prioritised in specification led projects.

LIQUATHANE® Water Based Flooring Top Coat

LIQUATHANE® is a water-based, two-part urethane flooring top coat designed for internal environments where low odour and low VOC levels are required. This makes it particularly suitable for occupied buildings or projects delivered in stages. 

Architects often specify this top coat for retail environments, commercial interiors, warehouses, and residential grind and seal applications. Its semi-gloss finish provides a softer visual outcome compared to high-gloss polyaspartics, supporting design-led interior schemes. 

It is important to note that LIQUATHANE® is not suitable for areas subject to hot tyre pickup. This limitation should be clearly addressed during specification to ensure correct system alignment. 

LIQUATHANE® MATTE Flooring Top Coat

LIQUATHANE® MATTE offers the same low VOC and water-based benefits as its semi-gloss counterpart, while delivering a matte finish that reduces glare and visual reflection. 

This product is frequently specified for commercial interiors, retail spaces, and residential projects where understated finishes are preferred. Matte surfaces can highlight substrate preparation quality, making coordination between design intent and applicator capability especially important. 

As with LIQUATHANE® systems, suitability for vehicle exposure must be assessed early in the design process. 

TETRATHANE® Urethane Flooring Top Coat

TETRATHANE® is a single-pack, moisture cure urethane flooring top coat with strong UV stability, allowing it to perform across both internal and external environments. Its versatility makes it suitable as a standalone topical coating or as a top coat over EPO100® epoxy systems. 

Specifiers regularly nominate TETRATHANE® for garages, hospitality venues, cold storage facilities, and transitional spaces that move between interior and exterior conditions. Its performance under varying light exposure supports broader material continuity across a site. 

As a solvent-based product, TETRATHANE® requires careful planning in occupied environments. Ventilation and staging should be incorporated into project documentation.
