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

Very happy with the results. Definitely made my grout look better. Some areas needed to be applied twice but overall am pleased. Easy to use and looks good.

There are many negative comments (1* and 2* reviews) on the Amazon website but if used carefully, this is a good product.I Bought this pen a few weeks ago. After less than a dozen tiles the tip frayed and the pen became unusable. I called Unibond to "complain" and they kindly sent me a replacement. Using the replacement, I was much more careful how I used it and the results were very good. Here are my "tips" for a good result:1. Shake the pen vigorously when first removed from the packaging.2. Press tip CAREFULLY on a non abrasive surface for a few seconds to allow the fluid to flow (I used an old tile off-cut).3. Apply the tip to the grouting GENTLY and at an angle - rather like drawing a line. DO NOT PRESS HARD on the grouting as this will cause the tip to fray! Turning the pen slowly as the fluid is applied will help to preserve the tip.4. Shake the pen frequently every 2-3 tiles and repeat 2 & 3 above until the job is complete.I have now "revived" all the tiles in my bathroom and shower and the grouting looks great! As I have said, a good product if used carefully. If Unibond read this, I suggest better instructions could be provided!

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.

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.

Really easy to use, worked well and found it easy to clean if I got any onto the tiles. Instructions easy to follow.

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 👎

The media could not be loaded. Very good product… I m actually surprise, how Is work. I will do free coats.

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.
