Dunlop Easy Clean Epoxy Grout Questions & Answers

No. Have only used inside.

Hi Geoff, yes the exact ratio. That means equal parts of each, so you can mix 100ml of each or 1litre of each, as long as they're equal.

Thanks heaps for that. So would it be recommended to mix small batches and see how I go ?

Please ask Dunlop. I am a home handyman and not qualified to answer your question.

I did manage to use small quantities to test its strength and suitability on old tiles but it is obviously more difficult to get the ratios right. I took all the old grout out, so I can't really help you with going over cement grout. But I guess it's like anything else, the better the surface it has to adhere to, the better it works. Probably depends on how good your old grout is in the first place.

To make up in smaller batches, what I did was to weigh the powder and divide into two parts, then divide both liquids into two equal parts. This way you can do smaller sections at different times.

Hi - I would probably wait until it is cooler. The warmer the weather, the quicker it sets. There is nothing worse than mixing a batch and have it start to set half way through, you end up rushing and doing a poor job. Speaking from experience!

Sorry but I've really got no idea. I've only used it in a shower and it is really obviously dry and hard after a few hours. I think I left it 48 hours to be sure. Might be worth giving Dunlop a call as I am only a handyman not a timer.

Hi Bill, there's a table on this page that sets out how much you'll need. external link  For 600x600mm tiles with a 5mm grout line you'll get a coverage of about 12m2 per bucket, so for 45m2 you'll need about 4 buckets. But alwasy best to buy a little less than you think as you can always go back and buy more, you don't have to grout the whole thing in one sitting. Just start where you left off, when you feel like it. Hope this helps.

I'm not a tiler - just to qualify my remarks. However I tried 2 non-epoxy based grouts in the base of our tiled shower and none did the job for very long. I even used waterproofing compounds on the grout afterwards and this was poor too. This one being epoxy based was totally different and has lasted about 9 months now and looks as good as the day it went down. It has not stained or leaked at all. It looks great too. I didn't need to silicon the edges either as it formed a really strong bond. Don't miss that silicon! In my case it has certainly been suitable for a waterproof shower tiled base.

Hi Palf. I found it straight forward to mix smaller quantities. When I mixed I did measure quantities really carefully so as not to get any colour or texture changes between the two batches and it has turned out absolutely uniform. My shower base has big tiles and is about 1500 x 1000 mm. I did it in two batches and cleaned as I grouted. That is I put the grout over quite a small area and cleaned it to a reasonable extent before proceeding. I used a textured sponge in warm water which lifted the excess quite well. My tiles are reasonably smooth and cleaned very easily. I could have done it in one batch as it was a cooler day but I was not confident to do so having not used this material before. My grouting is still perfect after a few months and is impervious to dirt. It has also sealed the horizontal joints between wall and floor where I have always used silicon before - don't miss the silicon! I will never use cement grout again in a situation like a shower base. There are probably other great products out there, but this one was easily bought at Bunnies and has worked really well for me.
