UniBond Anti Mould Sealant

Best grout pen I've tried. Nib stays in shape and lovely, bright white finish to grout really freshens up old tiling. Easy to use.

Actually did the job. Bathroom needed a lift and really did made a big difference. Would buy again

Old looking, discoloured grouts are white again. The pen is easy to use, compact (in fact, you might misplace it easily). Make sure the grout is clean, moudless and dry first. I cleaned it with some grout cleaner and the dried for a while as well as with a blow dryer to be sure. Just shake it, prime it by pushing it on some cardboard and then gently go over the grout, one even stroke. I did not really press, I coloured the grout and it came out clean, white with not leaks. The tip is not thick and the liquid flows nice and consistent. I couldn't believe it, after all the products I had tried, this one worked. It says to repeat after an hour, but my first pass was already fine. Amazing little product.

The UniBond Grout Reviver Pen is a simple and easy-to-use product designed to refresh discolored grout, giving tiled surfaces a cleaner and brighter look. While it’s a handy tool for minor touch-ups, it may not be a long-term solution for heavily stained or deteriorated grout. Pros: ✅ Quick and Easy Application – The pen-style design makes it convenient to apply without the mess of traditional grout. ✅ Instant Brightening Effect – Works well on lightly stained or faded grout, providing a whiter and fresher appearance. ✅ No Strong Odor – Unlike some grout paints or sealers, this pen has minimal odor, making it more pleasant to use indoors. Cons: ❌ Not Ideal for Deep Stains or Heavy Wear – While effective for surface-level discoloration, it may not fully cover deeper stains or fix cracked/damaged grout. ❌ May Require Multiple Coats – Depending on the grout’s condition, more than one application may be needed for an even finish. ❌ Durability Varies – The effect is not long-lasting in high-moisture areas like showers, where it can fade over time. Verdict: A Handy Touch-Up Tool, but Not a Permanent Fix The UniBond Grout Reviver Pen is a useful, budget-friendly option for quickly refreshing grout in kitchens and bathrooms. However, for deep stains, worn-out grout, or long-term results, re-grouting or using a more durable grout paint might be a better choice. ⭐⭐⭐ (3/5) – Good for quick fixes, but not a lasting solution for heavily stained grout.

I bought 4 of these ! There amazing ! The grout is clear white again I love these and was satisfying using it easy to use like a pen honestly but this !!! No mess at all

Works well

Pointless. No paint comes out unless you push down on the nib. If you push down on it the nib it frays out and becomes fairly useless. Couldn’t use it after a couple of meters. I would say it was a waste of money but it’s given me an opportunity to rant about something mundane.

Easy to use, even with dexterity issues, strong white colour, looks good

Did the work.

Easy to use BUT the pen tip wears out fast

Before using make sure to follow instructions. Initially nib would be dry, you need to press against a hard surface, so that the nib goes in breaking the seal and the white paint fills up the nib and then you can start using it. Everytime you feel the nib is dry you need to repeat this step. 7ml is less and costly. Maybe better to buy a white paint and a small brush and repaint the Grout.

I went over some grout lines which now look so much better.

Es carisimo por la cantidad de producto y por lo tanto cunde muy poco. No lo recomiendo por esta razón si tiene más de 3 metros cuadrados. La verdad, es un engaño.
