if the fish are in the pond use resin, if you buy the good stuff (ill find a link) you wont need that much you dont need to bladder it on as a few dots will hold it

if the pond is empty id use mortar

i did have a large amount of 2 part resin i promised to another member but it wasnt usable so it was binned, that will teach me to keep things wrapped up

I fitted mine after the pond was populated.

1cm wooden bead round the inner edge. Then concreted them into place. The bead stops any motor entering the pond.

Once all set I used black polyurethane to cover the wood.

I have just finished setting my stones this week and I used mortar. If you take your time to do each one carefully, it can be done with the fish in the pond.
They were very inquisative to know what was going on, and followed me to each stone that I did

Quite entertaining really

Hi Ben,

When our pond was built, the guy used mortar to fix natural slate. To me the mix looked a little weak but after 8 months we were leaning against the pond when one of the slates moved

. After a quick look at the rest, only one was still bonded down

.
We had to drain the pond to sort out the fibre glass (fish were always marked and we were pulling one out every week because of damage). Anyway we removed all the old mortar and bedded the slate back down with epoxy resin and kiln dried sand. These will never move

.
As for cost i'm lucky enough to work with resins and got some "samples" from one of our suppliers. We had to set 14m x 300mm on a bed of 25mm and used 5 bags of sand and 4 x 7.5kg of epoxy resin, the best price I could have got it for (apart from free) would have been £200 for the resin.

A word of caution, with many 2 part resins when in their liquid form they are a hazzard to the enviroment and WILL KILL your fish but if mixed and used correctly, once cured are perfectly safe.

If you decide to use mortar add pva to the mix to help it bond to the granite

Hope it helps

Regards Mark

Hi Ben

I used 10mm slats spaced about 36 inches apart fixed to blockwork, then mix your mortar add dye if wished, and flick onto wall, then use a piece of straight board longer than 36 inches, lets say 50 inches, and start at bottom of wall using a side to side action until you reach the top, flick on more mortar on any holes, then next day take off slats and fill in , apply a light coat of mortar smoothing as you go with trowel. see photos hope this helps, mine still work in progress at this stage.

I rendered mine recently.
Didn't use any slats and did it in one go.

4 to 1 mix
Plasters square trowel.
Base coat on nice and rough.
Smooth out roughly
Scratch it horizontially.
Leave for a day
Next coat on.
leave for an hour and float off.
