Resin & Epoxy Flooring: Complete Guide

Why It Matters

Plain Concrete Isn't a Finish — It's a Substrate

Bare concrete floors dust, stain, crack, and wear unevenly under real traffic — forklifts, pallet jacks, foot traffic, spills, and repeated cleaning. Resin flooring exists to solve this: a properly specified epoxy or polyurethane system gives you a seamless, hygienic, chemical- and abrasion-resistant surface built for the environment it's going into, rather than a floor that's simply "good enough for now."

The catch is that resin systems are not one-size-fits-all. A thin-film coating that's perfect for a retail showroom will fail quickly under forklift traffic in a warehouse, and a heavy-duty polyurethane screed is often more system than a light-use office floor needs. This guide walks through the system types, how to choose between them, and what affects a resin floor's success over time.

Resin Flooring System Types

Tswanacrete supplies Technical Finishes' resin flooring range in Botswana. The right system depends on traffic loading, chemical exposure, hygiene requirements, and budget.

Water-Based Epoxy Coating

A twin-pack, water-based epoxy such as Solidkote WB Epoxy gives a breathable, easy-clean, semi-gloss or satin finish with very low VOC content, and can even be applied to green concrete less than 28 days old. A cost-effective option for floors and walls where a full resin build-up isn't needed.

Self-Levelling Epoxy Systems

Solvent-free, self-levelling epoxy systems like Solidflow SL 1000 (1mm) create a smooth, seamless, hygienic surface with strong abrasion and chemical resistance — well suited to food preparation areas, pharmaceutical spaces, and commercial kitchens. Solidflow SL ESD is an antistatic 1.5mm variant for electronics assembly or server rooms where static control matters.

Decorative Quartz-Broadcast Systems

Solidflow Quartz (2mm self-levelling) and Polyscreed Quartz (power-trowelled) give a coloured, speckled quartz finish that combines decorative appeal with the abrasion and chemical resistance of a full resin system — popular in showrooms, retail spaces, and upmarket commercial environments.

Polyurethane Floor Screeds

Technical Finishes' Polyscreed range scales by thickness to match duty: Polyscreed SL (2.5mm), Polyscreed MD (4mm), and Polyscreed HF (8–10mm) — all sharing high impact resistance and Shore D 80 hardness, with the thicker builds specified for the heaviest mechanical loading, forklift traffic, and thermal shock, such as food processing facilities, cold storage, and production environments.

Polyurethane Floor Coatings

Solidkote PU is a tough, single-pack, moisture-curing polyurethane coating (not recommended for exterior use), while Solidkote Impact is a high-build, solvent-free polyurethane system engineered for exceptional impact and abrasion resistance — a strong option where floors take a harder daily beating than standard epoxy is built for.

Chemical-Resistant & Specialist Systems

Solidguard HCP is a chemical-resistant epoxy coating with nil water permeability, suited to battery rooms and chemical storage areas. For food-grade or potable-water tank linings, Technical Finishes offers specialist made-to-order systems — these require project-specific specification and confirmation of current certification, so speak to us directly if this applies to your project. Solidguard PUR is an aliphatic polyurethane topcoat used where UV stability and colour retention matter. System selection must be based on the specific chemicals or exposure involved.

Substrate Preparation & Repair

A resin system is only as good as the concrete underneath it. Worn, damaged, or uneven floors often need a repair overlay before a resin system goes down — Technical Finishes' Solidscreed 90 (high-strength industrial overlay screed) and Solidscreed 400 (polymer-modified overlay for 10mm+ builds) are used to resurface and reinstate damaged concrete, while Solidkote 110 is a wet-to-dry epoxy bonding agent used to bond new toppings or repairs to existing concrete.

Where the concrete itself has deeper structural damage — spalling, exposed reinforcing, or significant cracking — that's a job for structural concrete repair first, not a floor overlay. See our concrete repair guide for that process.

How to Choose the Right System

A handful of project-specific factors should drive the decision, not a default preference for one resin type.

Traffic & Mechanical Loading

Forklifts, pallet jacks, and heavy foot traffic call for thicker, more impact-resistant systems than a light-use office or showroom floor.

Thermal Cycling

Bakeries, cold stores, and production facilities with repeated heating and cooling generally favour polyurethane's greater flexibility over standard epoxy. See our epoxy vs polyurethane comparison for the full breakdown.

Hygiene & Chemical Exposure

Food-grade, pharmaceutical, or laboratory environments need seamless, cleanable systems — and sometimes FDA-compliant specialist coatings for direct food or water contact.

Static Control

Electronics assembly, server rooms, and similar environments may require an antistatic (ESD) system rather than a standard epoxy finish.

Aesthetic Requirements

Retail, showroom, and commercial reception areas often justify a decorative quartz-broadcast finish over a plain, functional coating.

Budget

Thin-film and standard self-levelling epoxy systems are typically more cost-effective than heavy-duty polyurethane screeds — but underspecifying for a demanding environment usually costs more in early failure than it saves upfront.

This is exactly the kind of decision our technical team can help with. Tell us about your environment, traffic, and chemical exposure, and we'll recommend a system with the Technical Finishes documentation to back the specification.

The Application Process: What to Expect

General principles apply across most resin systems, though exact steps, pot life, and cure times vary by product.

1. Substrate Assessment & Moisture Testing

Checking the concrete's condition and moisture content before any system is selected — a step that's easy to skip and expensive to regret.

2. Surface Preparation

Grinding, shot-blasting, or diamond-prepping to remove laitance and open the concrete's pores for a mechanical bond.

3. Repair & Priming

Patching damaged areas with a screed system and applying a bonding primer where the chosen system requires it.

4. Mixing & Application

Working within the product's pot life — often as short as 15 to 30 minutes — while applying by trowel, roller, or squeegee depending on the system.

5. Curing

Cure times vary significantly by product: some systems allow foot traffic in 12 to 16 hours and reach full cure in around 7 days, while others take longer. Always confirmed against the specific data sheet.

6. Topcoat & Detailing

A UV-stable or chemical-resistant topcoat is applied where the base system needs additional protection or colour stability.

Exact pot life, coverage rates, and cure times vary by product and must be confirmed against the current Technical Finishes data sheet for the specific system selected. Installation should be carried out by suitably experienced applicators working to the correct specification — talk to us about installation options, including through PourEpoxy, our approved applicator.

Why Resin Floors Fail

Most problems trace back to a handful of recurring causes.

Untested Moisture in the Slab

Rising moisture vapour through concrete that wasn't tested first is a leading cause of blistering and delamination.

Wrong System for the Environment

A rigid epoxy in a thermally cycling environment, or a thin coating under forklift traffic, is set up to fail regardless of installation quality.

Insufficient Surface Preparation

Laitance or contamination left on the concrete prevents the resin from properly bonding to the substrate.

Exceeding Pot Life

Mixed resin used past its working time cures poorly and compromises the finished floor's strength and appearance.

Early Trafficking

Walking or driving on a floor before it reaches the manufacturer's specified cure time causes marking, indentation, or bond failure.

No Ongoing Maintenance

Using cleaning chemicals not tested against the specific coating, or leaving chips and gouges unrepaired, shortens a floor's service life.

Maintenance Checklist

Use only approved cleaning chemicals Repair chips & gouges promptly Avoid dragging heavy equipment Follow the product's cure schedule before use Reseal wear layers in heavy-traffic areas Inspect for early signs of delamination

Frequently Asked Questions

How long before a new resin floor can be used?

This varies by system, but typically light foot traffic is possible within 12 to 24 hours and full loading after 4 to 7 days at normal ambient temperatures, confirmed against the specific product's data sheet.

Can resin flooring be installed over old tiles or a failed coating?

Sometimes, depending on the condition and bond strength of the existing surface — but old coatings, loose tiles, or contaminated substrates usually need to be removed or properly assessed first, since resin systems rely on a sound, well-prepared substrate to bond correctly.

Does Tswanacrete install resin flooring?

We can support your resin flooring project from product supply through to installation, depending on what's right for your project. PourEpoxy is our approved applicator for epoxy and polyurethane installation in Gaborone — talk to us early so we can scope the right approach.

Is epoxy or polyurethane better for my floor?

It depends on the environment. Polyurethane generally handles thermal cycling and heavy impact better, while epoxy is often more cost-effective for stable-temperature environments with standard traffic. See our epoxy vs polyurethane comparison for a full breakdown.

Can resin flooring be made food-grade or chemical resistant?

Yes — specialist systems exist for this, such as food-grade epoxy tank linings compliant with FDA regulations for contact with food and potable water. The correct specialist system should be selected based on the specific chemicals or food-contact requirements involved.
