Resin Overlay On Existing Surfaces Questions

Every question we get asked about resin overlay on existing surfaces, answered straight.

Questions

How It Works

  • Can resin be laid over an existing patio?

    Yes, if the base is sound, stable, and draining correctly. A damaged or moving base needs repairs first. Some surfaces are not suitable if joints are in poor condition or drainage falls are wrong, the specialist confirms suitability at the assessment stage.

  • What does ‘sound base’ actually mean?

    No active movement, no hollow sections when tapped, and drainage falls that move water away from the building. Concrete that meets all three conditions is suitable for overlay. If any of these fail, patch repair or a different approach is recommended before the resin goes down.

  • What happens if I delay and leave the surface as it is?

    Cracks widen with each wet winter, and water ingress accelerates base deterioration. A surface that is borderline suitable now may need full excavation in a season or two. Acting while the base is still sound keeps the overlay option open and avoids a more disruptive job later.

  • Why does the surface need primer before the resin goes down?

    Polymer primer creates the bond between the old surface and the new resin layer. Without it, the overlay can delaminate, particularly at edges and around drainage points. Primer is not optional; it is part of every correctly installed resin overlay.

  • What are the main risks of a resin overlay?

    Poor adhesion, cracking from base movement, and water problems if drainage is not right. All three risks are addressed at the inspection and preparation stage. If the base cannot be made suitable, the specialist will say so before any resin is mixed.
