How to use pond foam - black waterfall pond expanding foam

Love your videos. By far the best I have seen. What are the disadvantages of using mortar when compared to foam?

Mark, in other videos you anchor Willow Moss with the Waterfall Foam. Can you confirm that the moss will continue to grow and flourish in the cured foam?
,

thank you mark for the great advice and tips. My go to advisor.

I see you directly put foam on the liner, after 6 or 7 years, when you wanna remove the old foam, will the liner be damaged?

Mark
Can you use normal expanding foam or does it have to be specific for ponds/fish
Regards
Jim

Nice Mark!

Thank you for your great video, i wish I had seen your tips before I built my pond. Have a persistent leak on my waterfall, got some black foam and your video was so informative and gave me tips that I would never thought of. Thank you my Pond Guru. You are my “Go to Guy” in the future my valuable Gem.

Thank you for this Great explanation and your practice insights. Really helpful 👍🏻

Excellent what and how-to video. More like this for us beginners please.

Hi mate, good job, where do you get your foam from see some on ebay there are 3/4 all the same make and one don't say its fish safe but its say its an adhesive would you use it, just because it don't say its fish safe is it really going to kill all the wild life......

Been doing a marathon on your vids!! Keep up the good work!!

I wish you would come theUnited States and build me a fish pond. Thank you for all great videos. Jerry S

Great video. Watching your video just gave me an idea. I hope it works. Floating base for pond plants are really expensive. You mentioned it will float. So I thought of applying this waterfall foam to the plant basket around the sides. Thank you

Who do you know in eastern PA? Thank you

Hi Mark I had two questions I’m struggling with my waterfall going into my pond is there anyway I could get your email address so I could send you a pic and show you what I’m confronted with

Good old British weather. I love it 😁

Hi Mark. Is the DIY grade foam the same actual foam, but just with more basic can/applicator? Also do you use a liner underlay AND an overlay? Cheers!

Hi Mark, is it necessary to use the foam? Does it matter if water gets behind the rocks? I’m only building a small wildlife pond

Very informative Mark thanks.

You just forgot to mention the 2 most important things:
Where to buy?
How many cans in one normal size pond?

Great video ! Have you ever had any issues using cement mortar to set large stones ? I’ve heard people say cement based mortar is not safe for fish ? I’m restoring a large pond at my house and the stones were set with mortar

Hi Mark. Thanks for this video it’s really useful. Can you tell me where I can purchase this and the applicator in UK please ? Thanks. Dom

Great video, very helpful. Advice please. We bought quite a powerful pond pump because to make sure it could pump the water to the top of the waterfall but are finding that the flow rate down the waterfall is too fast and splashing outside the membrane so potentially losing water. The pump was quite expensive and does not have a regulator so is there a solution rather than changing the pump?

I was looking to buy some, but only doing this once, so seems expensive to buy the one you used. So can I use a generic aplicator gun with the Aquascape professional grade foam?

tell them to bring their sheets in

Thanks for your time.

I was liking the videos but when I seen you can only buy what he recommends out of other brands of expanding foam from his website, he’s talking nonsense, and the applicator gun is such a rip off.. you can buy one of these for £10, I wouldn’t waste your time buying from him

Great video! Has your washing dried yet? :D

Can I stick moss to the pond liner with waterfall foam? Will it adhere well enough? Great video!

Hi will this stick rock to the liner for my stream and waterfall…?

I have a tear abot 24" long 1-2" wide. We have used a patch that lasts about a year. Could I possibly use the foam ang "glue" stones over it to seal the crack? Plain clay underneath. The edpm patches don't seem to stick when it gets gold or stays under water. Thanks

hahah the washing on the line

Hi
Please can you advise where I can get this from?

Just found your video, thank you Mark! I’m a novice aiming for big things with my pond… already part filled with a massive stack of rocks ready and waiting! Will go and buy the foam now . Quick question how much do you need for a decent size 3 tier waterfall? Would one can do it?

No matter how much of this stuff I use I still have a leak under a guide stone on top of my spillover rock. How can I fix this problem? And how can I get the water to fall over the edge smooth instead of folding under and running under the rock?

Good stuff. Thank you.

Two days after using my hands with pond foam I am still struggling to get it off. Maybe I was unlucky/stupid but it’s horrible stuff to deal with manually or with gloves as it is so cloying and sticky (unsurprisingly). I would strongly recommend that it is very unsafe to just use your hands to handle or manipulate this stuff. Follow the H&S guidance on the can as I did what the pond advisor did and it turned out very badly for me.

Can this be applied underwater? Will it setup and plug a pipe full of water?

Thank you so much for being very precise with your explanation. I have bought several brands of PU Pond Foams - the workers most likely did not shake the cans enough. Our waterfall is leaking everywhere. It's a mess. The PU Foam turned into a sponge-like material - it holds water - and yes, my waterfall is leaking. They then turned to industrial foam which I am not happy with at all. So basically you are saying that these Pond Foams will never turn hard and are NOT water-tight - and do they all turn into a sponge-like substance which holds water? So - the only thing that will prevent water from leaking is the rubber underlay?

Do you think this product is safe to use on wells, we need install a steel cage at 80mts deep to handle a mild colapse and erosion, there is a 10 to 20 cm organic gap around the cage,, its usually enough to use the steal mesh, cage but in my mind, its would work, amazing if foam, with it dry, and how long with it last.

Go off = set. Also, this was not a very helpful video. I am going to get some foam, and hopefully get things right, but I would not give this video any credit whatsoever with my success. My failure yes, but not my success.

Can I seal cracks in my concrete pond with this foam? I tried silicon chalk ten years ago and the chalk is coming loose now. Can I trowel it flat over areas that may be leaking? Thanks for this information. I never heard about this product.

Is there a more British scene than the washing outside during a thunderstorm - with absolutely no one concerned whatsoever? 😂 Classic

Great video very comprehensive & informative! Thanks Mark 👍

Awesome details! Thank you for providing so many helpful tips.

Super appreciate solid demonstration of black landscape foam by a professional. Considering using this type of product, and there just isn't much out there.

Excellent! I can stop watching 'how to foam a waterfall' videos now. Wish yours had come up first. You are the only one that I watched that answered the question about using it on wet rocks. Subbed.

Thanks! Any reason why you cannot put the stone grit on the wet foam as you go? Cheers from down under 🇦🇺

Cleaning foam guns with pipe cleaners lmfao. What about foam gun cleaner just Screw it on gun instead of foam and press trigger it dissolves unset foam on contact inside gun. Also has a spray attachment to spray on any foam on outside of gun.

👍
