We were given an ornate (& I reckon expensive) bird bath a couple of Christmas's ago. It's made from reconstituted stone or concrete with some initial protective coating.
The frosted water during the 'long winter' has crazed the finish & it won't hold water now.
Is there a clear treatment, impervious to water that I could coat it with?
I would like to save it.
:-\
Not sure of the real answer, but if you try anything that seals boats...?
Someone will be along with the real answer shortly...
???
Assuming you don't want to go along the varnish route... have you considered the waterproofing liquid used to stop water penetration on masonry ...
I had the same problem, used Thompson's water seal. Available at B&Q, builders merchants etc.
What about a clear lacquer, like the kind used on cars? Can get it fairly cheaply in Halfords etc
There is an official pond sealant type thing made by bondaglass voss
see: http://www.arghamvillage.co.uk/products/details/184.html
They used this on groundforce to make ponds out of flowerpots :)
might be a bit expensive though - the smallest quantity this company do is 500g for £7

Thankyou all for replies.
Sally, I think you may have answered the question.
A mate said that he had used a product but couldn't remember the name, but expensive!
If it's expensive, it usually does work. I'll investigate Bondaglaass Voss.
I'll report back!
