What Causes Poor Adhesion in Renewed Resin Floors?

Ensuring strong adhesion is critical when renewing a resin floor. If the resin doesn’t bond well, it can peel, blister, or wear away quickly. Understanding what causes poor adhesion is the first step to a more reliable and attractive finish.

Causes of Poor Adhesion

Poor adhesion often occurs due to contaminants like dust, grease, or residues left on the substrate. Moisture in or on the floor can also inhibit bonding between the old surface and new resin. Applying new resin without using a compatible primer to prepare the surface increases the risk of delamination. Thorough cleaning and drying before applying resin is essential.

How to Prepare for Better Bonding

Start by cleaning the floor thoroughly and allowing any residual moisture to evaporate. For most substrates—including concrete, tiles, screed, and timber—you should apply a suitable primer to enhance bonding. For example, Epoxyprimer offers excellent compatibility across popular floor types and helps maximise adhesion. Choose primers and resins suitable for your specific surface to ensure the best results.

When This Matters Most

If the floor is subject to high traffic or mechanical stress, poor adhesion can lead to early wear or peeling.
Moist environments such as basements require extra attention to surface dryness and the choice of products designed for such settings.
Project success hinges on careful preparation in both residential and commercial spaces where longevity is vital.
