Rayson technical answers · Singapore
Start with the substrate, operating exposure and shutdown window. Rayson connects the site question to the relevant system, product and published technical data.
01 · Start with what you know
Choose the route closest to your current situation. Each path has one clear next step instead of repeating the same product catalogue.
Start from peeling, cracking, ponding, moisture or wear. Diagnose the condition before discussing a system.
Diagnose the surfaceDefine traffic, hygiene, chemicals, temperature and the shutdown window available to the business.
Plan by industryOpen the current product TDS, document code and published data directly—without submitting a form first.

Not by default. The concrete should first be assessed for strength, contamination, moisture and the condition of any existing coating. The preparation method and primer are selected from that evidence; coating over an unsound interface only carries the weakness forward.
Check: strength · contamination · moisture · existing layers
Peeling, blistering and delamination describe symptoms, not the cause. Loss of adhesion can involve contamination, trapped moisture, insufficient preparation, incompatible layers or application conditions. Identify where the failure sits in the build-up before deciding how to repair it.
Record: location · pattern · layer · moisture · operating exposure
Chemistry is selected from operating exposure, not appearance. Epoxy systems are commonly used for hard-wearing interior floors; polyurethane finishes are considered where flexibility, abrasion or UV performance matters; PU-cement is relevant to heavier chemical, hygiene and thermal-shock conditions. Confirm the final product and build-up in its TDS.
Define: traffic · chemicals · UV · temperature · cleaning regime
Water, movement, falls, joints and UV exposure should be considered together. A traffic coating is not automatically a waterproofing membrane, and a membrane is not automatically a wearing finish. Define whether the project needs waterproofing, slip resistance, UV stability or a combined system.
Check: drainage · joints · movement · UV · pedestrian or vehicle traffic
No. The available window matters, but return-to-service planning must be checked together with substrate condition, temperature, coat sequence and the relevant TDS. Establish technical fit first, then plan application and reopening against the published product data.
Plan: access · coat sequence · temperature · inspection · reopening
Start with the product TDS to verify intended use, suitable substrates, mixing, coverage, application information and limitations. Use the product page for system context, and contact Rayson when the site conditions or required submission documents go beyond the published data.
Verify: document code · revision · intended use · limitations
This page provides preliminary technical direction. Final product and system selection must be confirmed against site conditions and the relevant technical data sheet.
03 · From site evidence to technical data
Do not work backwards from a colour or product name. Define the site condition first, then use published data to verify whether the product fits.
Record strength, contamination, moisture and the condition of existing layers.
Set out traffic, chemicals, temperature, UV, cleaning and the shutdown window.
Combine repair, primer, body coat, finish or membrane roles around the required function.
Check intended use, substrates, mixing, coverage, application information and limitations.
