Choosing between epoxy and methacrylic resins is key when it comes to waterproofing showers. Each resin comes with distinct properties suited to different surfaces and project requirements.
Epoxy Resins – Seamless Decorative Protection
Epoxy resins are valued for their ability to create continuous, attractive coatings on interior shower walls and trays. When applied correctly, epoxies deliver a smooth, watertight barrier with an option for custom finishes or tinting. For example, products such as “Vertical Glass” wall coating can be applied to tiles, masonry, or wood and provide a wash-friendly, durable finish ideal for areas exposed to frequent moisture.
Methacrylic Resins – Deep Sealing for Concrete
Methacrylic resins such as ‘Resinstone’ work differently by penetrating deeply into absorbent materials, especially bare concrete substrates. This creates robust internal waterproofing that helps resist moisture while maintaining some breathability. Methacrylic resins are well suited for prepping concrete shower tray bases before other coatings are added, ensuring a strong foundation resistant to prolonged dampness.
Practical Buying Tips: Which Resin Should You Use?
- For finished or tiled walls: Epoxy is ideal due to its seamless, protective decorative surface and compatibility with a range of materials.
- For new or absorbent concrete bases: Choose a methacrylic resin first for deep waterproofing, followed by a decorative surface layer if required.
- For clear, shallow layers: A multipurpose clear epoxy like “Trasparente” is suitable for up to 2cm thickness on shower trays needing a transparent finish.
When This Matters
If your shower project involves a concrete base or older masonry, a methacrylic product ensures moisture is blocked internally before decorative finishing. For most renovations and decorative upgrades, epoxy is the professional standard for wall surfaces and visible waterproof layers.
