What paint product should I use to paint a pond's inside wall?

I have searched the internet and have come across liquid rubber and epoxy paint as the options? 

 

Which ones work best and are any of the products to tintable to a particular color? Is there a particular product that you would recommend?

Re: What paint product should I use to paint a pond's inside wall?

Hi @kashgenius. Many thanks for your question, I'd be happy to answer it.

 

The product I would recommend is Crommelin pond sealer which is specifically designed to paint a pond's inside wall. It is a flexible water-based membrane, UV stable, fish and plant friendly, and used for waterproofing ponds. It is available in the colours sandstone, blue, clear and black. 

 

If you wanted a specific colour you could use an oxide mixed into a cement-based slurry to render the walls of the pond. You would then need to seal that with the Crommelins clear pond sealer for waterproofing purposes.

 

If you need further information about these products or had other questions, please let me know.

Thank you.

 

I have just discovered there are a few cracks and holes in the pond. What would be the best way to fill them up before I seal them with Crommelin?

 

Cheers,

Kash

Hi @kashgenius.

 

What is the pond made from, does it already have a coating on it, and how big are the cracks and holes? Some pictures would really assist me, however with the details provided I should hopefully be able to give you an answer.

Hi Mitchell, thanks for the super quick response.

 

The pond walls are brick and the pond inner surface feels like hard plastic. Not able to describe the material as this is an established home. At certain places inside the pond, I stand on the surface and it moves up and down.

 

The biggest hole is upto 2 cm in diameter. And there are maybe 3-4 more small ones. The pond was coated with a green material (although I do not what it is) and it is cracking as well. I am attaching photos and a video with this post.

@kashgenius,

 

That appears to be a fiberglass shell with a very deteriorated coating. The holes can be repaired with a fibreglass repair kit and most small cracks can be just painted over. My concern is that coating is really deteriorated and anything that is flakey or may come off needs to be removed with a scraper. It would also be a good idea to sand the whole interior down with a 120grit sandpaper. Correct PPE must be worn including a respirator, gloves, goggles and preferably disposable over-alls.

Brilliant! Thanks a lot. Yes the paint has deteriorated so the plan is to scrap it off. Sand the surface and then re-seal with the Crommelin. Hopefully all should come out well. 

 

I had earlier intended to convert this pond into something but given the rain and the inability to help the water seep out, I decided I will keep the pond as is but renovate it a little.

 

Thanks a lot for your help.
