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. ## Frequently Bought Together - Bonda G4 Pond Sealer Clear 500g - BOND IT CLEAR HA6 RTV Silicone Sealant Marine Aquarium Safe Water Fish Tank Adhesive - Bonda G4 Pond Sealer Clear 1kg --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/50892579-g4-pond-sealer-clear-500g](https://www.desertcart.pl/products/50892579-g4-pond-sealer-clear-500g) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-07*
