Review: It works - Very efficient,use old brushes have to dump after use, lovely water proof finish and easy to use,
Review: Does the job brilliantly…! - Used this to ensure no leaks on my new waterfall made of pure dry stones to match my pond. I put two coats on and it works perfectly. As a precaution, try not to put too much on your brush, just do small amounts at a time. It hardens in about 1.5 hours and then add a second coat. To save on your brushes, once you have done a coat, place in a plastic bag, squeezing out the air and it can be used again later. Great stuff for sealing stonework also.

## Questions & Answers

**Q: what happens if i wait longer than 4 hours to apply the next coat of g4 pond sealer ?**
A: I believe it is a question of bonding. If the first coat is still not completely dried it will bond better with the second coat. If it is cured completely, the bonding will diminish. This product is great for stones and bricks etc that has something that it can connect on to, less so for smooth surfaces like plastic or cured G4 for example. However, I have painted over G4 coats as a repair or just to touch-up long after the first coat, and it seems to still bond well. So the short answer is that optimal bonding should happen within 4 hours, hereafter still good though.

**Q: Does anyone know if this will dry with wet look I have coping stones that look really nice wet but not very good dry I’m hoping to keep the “wet look”**
A: It does dry with a wet look but it also darkens the stone. It is a yellowish brown colour when two or three coats have been applied. There is other coatings sold specifically for flags that gives a wet look. You may want to look at those first. G4 is made for ponds where it will not kill the fish, although it would do the job.

**Q: Can this be used on a perished linner**
A: Well I lcd a bird bath some years ago.with four coats of G4. It has stood a hard life with snow ice and even me scrubbing it so it is tough and is happy with multiple coats, which used a lot of the g4. In your situation I don't know the answer but if it was me and I wasn't risking  life & limb if it failed I would give it a go,  and use a good few coats.

**Q: Is it koi friendly?**
A: Sorry, Sony know as I used it to seal a concrete birdbath. Birds seem ok with it. Call their Customer Support, they were very helpful when I spoke to them. One other thing, it coloured the light gray concrete to a fawny brown so it is not transparent as stated.

### ⭐⭐⭐⭐ You may need more than you think
*by S***R on 28 April 2013*

Very effective sealer but it doesn't go a long way. I used it to seal a concrete bird-bath which kept losing water (and flaking) through absorption. I covered the whole stand, not just the bowl to stop winter damage and used almost 500ml with the recommended four coats. The first coat soaks in and the rest build up to leave a high gloss finish. Great seal which should avoid further winter damage but the birds had trouble getting a grip on the smooth surface. A bit of roughing-up with a file did the trick (on the sealant, not the birds) This will do for any non-toxic sealing job and looks like it will last a long time. Recommended. Note, (Oct 2013), after six months in all weathers: The finish is unblemished and has weathered to a slightly darker shade. No flaking or blistering and the bird bath looks ready to face winter. So, very pleased with purchase.
