Permatech
Staff member Alok personally guided a DIY customer through an entire garage floor coating project from product choice to final finish.
That level of advisory support is specifically why multiple reviewers favour Permatech over other specialist suppliers, not just because of the product range. The sample is small and review dates couldn't be verified, so it's worth confirming current stock availability and whether technical support staff are available when you plan to visit — walk-in or phone-ahead experiences may differ depending on staffing on the day.

About Permatech
Permatech operates as both a specialist product supplier and a technical advisory service — a combination that sets it apart from standard waterproofing contractors who only install. Staff member Alok is specifically called out for walking DIY customers through product selection, answering technical questions, and providing the step-by-step guidance needed to complete jobs like garage floor coatings independently using products such as the Megapoxy MC. That dual focus — serving both trades and homeowners who want to do it themselves — makes this a genuinely versatile destination. The team's product knowledge appears to be a genuine differentiator: multiple reviewers distinguish Permatech's expertise from other suppliers they use, not just from other contractors. Pricing is noted as competitive, which is relevant given that specialist construction products can carry significant markups elsewhere. With around 26 years of operation and GST registration as a trust entity, this is a long-running, structured business rather than a sole trader — which typically signals stability in supply chains and product availability.
Best for: DIY homeowners tackling garage floor or waterproofing projects who need guided product selection, trade professionals sourcing specialist construction materials, and anyone who wants technical advice from staff rather than a standard retail transaction.

Does Permatech support DIY homeowners or is it trade-only?+
Permatech explicitly serves both the general public and trade professionals. At least one reviewer completed a full DIY garage floor coating using Megapoxy MC with support from staff member Alok, who assisted with product selection and provided step-by-step application guidance. You don't need to be a contractor to walk in and get meaningful help. If you're planning a DIY project, it's worth calling ahead to describe what you're trying to do so staff can have the right products and information ready.
What kinds of products does Permatech stock?+
Reviews specifically mention Megapoxy MC as a floor coating product used for garage floors, and the business is categorised as a specialist construction product supplier. The broader product range appears to cover waterproofing compounds, surface coatings, adhesives, and related construction materials, though the full catalogue isn't detailed in available reviews. Multiple trade customers describe it as their go-to source for specialist products, which suggests a reasonably deep range. Contact them directly or visit to confirm availability for your specific application.
How knowledgeable are the staff at Permatech?+
Product knowledge is the single most consistent theme across the 5 reviews available. One long-term trade customer specifically states Permatech's knowledge is 'above any other supplier I use.' Staff member Alok is named for walking a DIY customer through product selection and application questions. Keep in mind this reflects a small sample of 5 reviews, so calling ahead to discuss your specific project is the best way to gauge whether the team can address your particular waterproofing challenge.
Is Permatech competitively priced compared to other suppliers?+
Pricing is mentioned positively in the available reviews, with one customer specifically noting prices are 'very very competitive.' Given the specialist nature of construction and waterproofing products, this is a meaningful point — specialist items often carry significant markups at general hardware stores. However, only a small number of reviews address pricing directly, so it's worth getting a quote or checking in-store pricing against your specific product needs before assuming across-the-board savings.
Where is Permatech located and who is it best suited for?+
Permatech is based in Wangara, WA, which positions it conveniently for Perth's northern suburbs. It appears best suited for homeowners planning DIY waterproofing or coating projects who want expert product guidance, as well as trade professionals looking for a reliable specialist supplier with strong product knowledge. With around 26 years of operation, it has the longevity you'd expect from a business that serves repeat trade customers. If you're outside the northern corridor, it's worth confirming whether they offer delivery for products or whether an in-person visit is required.
