Epoxy Resin for Flooring: 6 Problems Contractors Face—and How to Fix Them

Epoxy resin for flooring is one of the most popular choices for commercial and industrial surfaces. But when contractors run into problems like bubbling, peeling, or slow curing, it often traces back to product mismatch or poor prep.

In this guide, we’ll walk through six common flooring issues—and show you how to avoid them using the right epoxy resin for flooring.

1. Poor Adhesion to Concrete Substrate

Resin lifting or peeling off usually means the floor wasn’t properly prepped. Moisture, dust, or a lack of primer will kill adhesion.

Fix it: Use a high-adhesion primer with our 2118AB epoxy resin for flooring. This system bonds well even to porous or aged concrete.

2. Bubbles and Pinholes After Application

These form when air gets trapped—especially in warm environments or thick pours.

Fix it: Use slow stirring, thin coats, and choose anti-bubble resins like 2116AB low-foam epoxy. Maintain room temps around 20–25°C.

3. Yellowing from UV Exposure

Clear or light-colored floors can yellow in direct sunlight without UV resistance.

Fix it: Our 3136AB-SX UV-stable epoxy keeps finishes clear and bright—ideal for showrooms or garages with natural light.

4. Peeling or Delamination Over Time

Usually caused by expansion/contraction or layering over incompatible materials.

Fix it: Deep-penetrating systems like 2116AB-F help anchor resin into older surfaces. Check moisture and compatibility.

5. Slow Curing in Cold Weather

In winter, epoxy takes too long to harden—delaying project handover.

Fix it: Choose a cold-curing formula like 2118AB-W, which cures well even at 10–15°C. You can pre-warm drums indoors.

6. Cracks After Curing

Cracks result from shrinkage or using too rigid a formula on shifting concrete.

Fix it: Use a semi-flex epoxy like 2116AB-F that handles floor flex without breaking.
