What Epoxy Is — And Where It Is the Right Specification
A correctly specified epoxy system consists of three layers applied in sequence: a low-viscosity penetrating primer that bonds to the concrete aggregate beneath the surface dust, a pigmented base coat that builds colour and structural thickness, and a polyurethane or aliphatic topcoat that provides the surface hardness, chemical resistance, and UV stability. The result is a completely seamless, non-porous surface with no joints, no grout lines, and no recesses where contaminants accumulate. In any environment where chemical contact, hygiene compliance, heavy loads, or dust suppression are the primary requirements, epoxy is the most cost-effective system available.
The leading cause of epoxy failure in Saudi Arabia is undetected moisture in the concrete slab. Saudi concrete — particularly in new buildings and summer pours — retains internal vapour pressure for up to 18 months after the surface appears visually dry. When epoxy seals over an active slab, that pressure accumulates beneath the adhesion line until the coating delaminates. This is entirely preventable, but only with a sealed 60-hour moisture test before any material is opened. Every project we complete begins with this test — it is not optional.
If the primary requirement is visual impact — a surface with organic patterning, three-dimensional depth, and colour movement that shifts as light changes — that is a different material category. Metallic epoxy with mica mineral pigments is a separate system with its own chemistry, process, and purpose. This page covers the functional epoxy system only.

Questions About the System
Standard epoxy is a functional performance coating — solid colour, uniform, specified for durability, chemical resistance, and hygiene. Metallic epoxy is a completely different system using mica mineral pigments suspended in resin to produce genuine three-dimensional visual depth. They share a base chemistry but serve entirely different purposes. If visual impact is the primary requirement, see our dedicated Metallic Epoxy service.
Moisture is the primary cause. Saudi concrete retains internal vapour pressure for up to 18 months after the surface appears dry. When epoxy is sealed over an active slab, that pressure builds beneath the adhesion line until the coating delaminates. The second cause is skipped surface preparation — bonding the primer to weak surface dust instead of the structural concrete beneath. Both are entirely preventable with correct process and a 60-hour sealed moisture test before any material opens.
Often, yes. Fully bonded and structurally sound tile can be coated directly after surface preparation. We sound every tile during the site visit — hollow or cracking tiles transfer instability into the epoxy system above them. If more than 10–15% tests hollow, we recommend removal. Where the tile is solid throughout, we apply over it directly.
A correctly prepared system — moisture-tested slab, diamond-ground concrete, correct primer and topcoat specification — remains fully intact for 10–15 years before the topcoat requires maintenance. What ages is the topcoat gloss and hardness, not the bond to the substrate. The topcoat can be abraded and recoated without removing the base system. Systems applied without correct preparation fail within 1–3 years regardless of product brand or cost.
Tell Us the Surface and Environment. We Handle the Rest.
Before pricing any epoxy project, we visit the site, run the moisture test, assess the existing surface, and confirm the correct system specification for the environment. The site visit is free. The quote is fixed after it — no additions once installation begins. We cover the full Kingdom of Saudi Arabia.
