Unibond Grout Reviver Pen, White Grout Pen for Bathroom Grout Joints, Easy to Use Tile Grout Pen, Whitener for Restoring Discoloured & Faded Joints, 1x7ml

Brilliant! Made such a difference! So easy to use and will be buying again!

Pens work well if you dab them every so often . Don't press to hard or the rip will just full in on its self. Looks great when done and does go along way doe usage. Some pens can break pretty quick. Always get spares just incase

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 wasn't expecting much from this pen-style product but I have been very impressed, very easy to use also, good adhesion and looks good.

Easy to use good coverage well priced for 3 pack

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

Il prodotto ha la forma di un pennarello, con punta di 3mm circa, il colore del tratto è bianco. Sulle fughe verticali nessun problema, su quelle orizzontali è consigliabile tenere il "pennarello" in modo che sia sempre un po' verticale per garantire la costante "discesa" del liquido sbiancare. Sono molto soddisfatto in quanto solo sulle fughe veramente scure son dovuto passare 2 volte. Con 2 pennarelli ho sistemato le fughe di 3,5m di cucina. Attenzione a 2 cose: -il prodotto sbianca la fuga, non la crea, quindi se rovinata dovrà essere ricostruita -se avete fughe molto strette, potete tagliare 1 spicchio di punta x ridurla (io ho usato delle forbici) o lasciarla così e poi ripulire il bianco in eccesso dalla piastrella una volta essicato (basta strofinare un po') Molto soddisfatto della resa del bianco, e della resa in termini di metri lineari di fuga che 1 pennarello può fare. Sulla scatola sono indicate in modo chiaro le istruzioni

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.
