Let me start by saying I had BIG glitter dreams for my bathroom renovation. The Hemway Glitter Grout Additive promised to turn my basic subway tiles into a disco ball fantasy. Spoiler alert: it's not that simple.

The white iridescent glitter looks gorgeous in the packet - like crushed diamonds. But here's the reality check: you'll need WAY more than the recommended ratio (100g per 1kg grout) for visible sparkle. I ended up using nearly triple the amount (about 8 packets for 12lbs grout) just to get subtle twinkles.

Application was straightforward - just mix into dry grout powder before adding water. The consistency remained perfect, no clumping. But at $10 per tiny packet, this sparkle comes at a steep price. Pro tip: test small batches first to find your perfect glitter-to-grout ratio.

Where it shines (literally): mosaic projects or accent walls where you can really pile on the glitter. Where it disappoints: large areas unless you're ready to spend a fortune. The effect is beautiful when concentrated - like fresh snow catching sunlight - but disappears if spread too thin.

Final verdict? Gorgeous when used heavily, but consider premixed glitter grout for bigger projects. Save these packets for special accent areas where you want maximum bling factor.
