Tips on using Pondshield Starter and Pondshield Pro
Once the product has been opened, as long as it is kept sealed in a cool dry area the pot life is 12 months.
It is important to mix Pondshield Pro thoroughly to ensure the two parts are perfectly mixed, a mixer attachment on a drill is ideal however take care not to aerate the sealant.
PondShield Pro should only be mixed when needed and only the required amount should be mixed at any one time; no more than 1 – 2 square metres worth at a time as it can harden quickly depending on the temperature. It cannot be stored pre-mixed and then reused.
The required amount of product must be poured from the original container into an empty, clean ice-cream container or other vessel and then used and applied at the recommended rate; do not make the sealant “go further” – use more sealant if required.
A light mist of water sprayed on the concrete before painting particularly in warm weather will allow the sealant to get a good foothold on the concrete.
The paintbrush should not be dipped in and out of the original container as bacteria will cause the product to go off.
Also ensure that the correct thickness of the pond sealant is achieved, if the sealants are applied too thinly, a waterproof barrier will not be achieved and the pond may not hold water.
Any “sharp” angles in the pond, gaps in between bricks/blocks and overly rough or textured surfaces such as the pitting that occurs on limestone blocks should be smoothed out with render prior to sealing.
Old pond sealant cannot be painted over and should be completely removed using a diamond tipped grinding disc or high pressure gurney until the raw concrete/render is exposed. Before the pond is filled with water it is recommended to lightly spray and gently brush the sealant with a soft bristled broom to remove any residue, soak up the water pooling in the bottom of the pond with clean towels and repeat. The pond can then be filled with water.
