Why Regular (Cement) Grout Fails in Showers
- Porous by nature – it absorbs water, stains, and soap scum.
- Requires sealing – and resealing, which most people don’t do.
- Color shifts & hairline cracks – especially under constant moisture and heat.
Why Epoxy Grout Is Different
- Non-porous – resists water absorption and stains.
- No sealer needed – one less maintenance headache.
- High strength & low shrinkage – no cracks and callbacks.
- Color-true – what you install is what you keep.
Why SpectraLOCK® Pro Premium Is the Pick
- Installer-friendly working time and smooth spread.
- Consistent color across walls and floors.
- Proven in commercial and residential showers.

How to Use It in Your Shower
- Mix the three components: Part A (Resin), Part B (Hardener), and Part C (Color Powder) — per instructions included.
- Spread with an epoxy grout float, forcing grout firmly into joints.
- Clean on schedule using the included wash packets/sponges to remove haze.
- Let it cure fully before use. Enjoy a low-maintenance, mold-resistant shower.
Tools You Actually Need
- Epoxy grout float & margin trowel
- Two clean buckets, sponges, microfiber towels
- Timer (don’t wing the wash times)
- Gloves; good ventilation
Real-World Notes (No Sugar-Coating)
- Working time is finite. Mix manageable batches. If you overmix, you’ll rush and leave haze.
- Temperature matters. Hot rooms shorten open time; cool the space or your mix.
- Textured/pebble floors: It’s fine to use, but plan extra time for thorough cleaning of the surface.
