This unibond 7ml grout pen is a great product & certainly revives things well to nice & crisp white. Told that it is easy to apply & that you can be more precise with it being pen & that there is no need to press too firmly & that it quickly dries within 60 minutes. & a tip the nip needs to depressed quiet a few times until the product flows you can think this isn’t working got a dud it just takes a while to come through. & when the nib frays pull it out & use the other end. & that a good thing is if any mishaps or have applied too much you can simply remove it with a damp cloth. This grout pen is great to restore discoloured grout & revive dull areas. Ours is used around the toilet because it goes off white quickly & odd tiles the white grout, a great product that saves you money & the need of replacing the grout in e.g bathroom/kitchen & so on.

Good, need a steady hand! also half the price of the shops!!

I bought this and am very impressed. Gave my white kitchen tiles 20 years old plus a good clean and this went on very easily. Definitely worth a try and good value

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 FixThe 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.

They made my grout look phenomenal. So easy to use, it's literally just a felt pen.Once it's dry it won't rub off, but while you're applying it's super easy to get excess off. Doesn't smell at all.Seen a few reviews saying it runs out fast. I will say, the nib does wear fast but that's because grout is rough. If you keep pressing it down, it should last longer. I did one rooms worth of grout and it was still usable afterwards so it doesn't run out mega fast

This so called product, (The Unibond grout reviver pen) is the biggest load of rubbish & waste of money I have ever purchased, I consider myself as quite adept at DIY & enjoy taking on most jobs & after decorating my bathroom I realised that due to the condition of my tiles & grout being quite good I would try the aforementioned grout pen to spruce them up, (what a mistake that was to be).I followed the instructions to the letter which isn't rocket science, shake the pen, press the nib, ( but not too hard ) onto a piece of paper until the liquid is released, ( so far so good ) then gently squeeze ( but not too hard ) onto the grout & gently move along grout line, after doing five 6" tiles the nib split into what looked like frayed string & therefore wouldn't press back into the pen to release the grout liquid rendering it about as useful as a chocolate fire guard.I spent nearly £12 for 2 of these pathetic, useless, infuriating little pieces of rubbish & ended up actually scraping out & regrouting my tiles which I actually enjoyed doing a lot more than messing about with the aforementioned pile of junk.This is only my experience & my opinion but please be careful when thinking of buying this product, it's equally annoying as I've bought Unibond products in the past & never had a problem, 0 out of 10 & no stars for this one 👎

Just had to leave a review. I am a terrible DIYer! This pen is amazing! So easy to use and results are fantastic.

I really wasn't expecting much, but it's done a surprisingly decent job, not bad at all, although I'm not sure how long the whiteness will last.
