Whether you are a DIY enthusiast or a professional, these instructions help ensure lasting results and prevent common pitfalls in wet areas like showers.

Step 1: Prepare the Surface Thoroughly
Proper surface prep is crucial for adhesion. Begin by cleaning all shower surfaces—tiles, cement, or brick—removing limescale, soap residues, and loose particles. Any traces of moisture or contaminants will compromise the resin bond. For tiled showers, degrease thoroughly; on cement, allow at least 7 days of drying time after any repairs or installation. Fill any cracks or joints with a suitable filler and sand the surface for better keying.
Make sure the area is well-ventilated, and protect fixtures with masking tape and sheets.
Step 2: Prime and Seal with the Correct Resin
On concrete or cement shower bases, a primer coat helps seal and waterproof the surface. Apply “Resinstone” – One-Component Methacrylic Resin for Concrete Floors and Driveways with a roller or brush in an even layer. This step ensures the substrate is protected from rising damp and prevents bubbles in your decorative coat above.
Allow the primer to dry fully—typically 12 hours—before proceeding.
Step 3: Apply the Decorative Resin Finish
Mix your chosen resin, such as “Vertical Glass” – Thick Resin Decorative Wall Coating, following the manufacturer’s instructions. Use application tools suited for your surface: a spatula for vertical and sloping shower walls or a roller for flat areas. Spread the resin in even, controlled layers, working from the top downward to catch drips.
Avoid over-applying resin on vertical surfaces; thinner coats give a vitrified, glass-like look while thicker coats can add durability but may sag if overloaded. For creative finishes, you can tint the resin or layer colours as desired.
Step 4: Curing, Finishing, and Maintenance
The resin must cure undisturbed for at least 48 hours in a dust-free, ventilated area. After this period, surfaces can be lightly sanded for a satin look or left glossy for maximum reflection. Wait at least 7 days before exposing the shower to heavy water use.
Routine cleaning is simple: use a mild non-abrasive cleaner. Avoid acidic or harsh chemicals which can cloud the resin surface.
Tips and Common Mistakes to Avoid
Ventilation and safety precautions are essential: Always wear gloves and ensure good air flow when mixing or applying resin. Always check surface dryness before coating. Don’t rush the drying times between layers. Using too much product in one go can cause sagging or bubbles, especially on vertical surfaces.
Intensive sanding should only follow after full curing. If working for a custom effect, practise on a spare tile first to perfect your technique.
