Sealants and Adhesives

The most important part when selecting any sealant - whether it is the clear Silicone Sealant or any other type of sealant is to remember that it should be 'non toxic' ... especially if you are sealing round pipe work which will be in close contact with the pond water ... this of course includes the water held in the filtration system ..

Naturally we stock only the sealants and adhesives that we know are pond safe ... which of course are going to cost more than the sealants you can buy from the local D.I.Y. store etc ...

The Silicone we have is clear and comes in the tubes which will fit any of the normal size frame guns available .. and it is just a matter of popping the new tube of silicone into the gun - and applying it to where you need it ...

Try where possible to 'tool' it once it is applied .. this is done normally, although we should not do so, by wetting your finger and then wiping gently over the joint which smoothes it out when it can then cure and form a good seal, as well as look a respectable job also ..

We also stock a Polyurethane Sealant which is ideal for sealing round the bottom drains and pipe work, if you are using a pond liner .. it not only seals the joint it is also an adhesive so it really does stick to both surfaces ... this can also be 'tooled' in the same manner as the clear.

All silicone and adhesives should, where possible, be allowed to cure for 24 hours before being submersed in water...


Polyflex Sealant (Black) General Purpose Sealer and Adhesive

A moisture hardened sealant. A sealer with strong adhesion but always remaining flexible under all conditions. Capable of sealing seams and joints and bonding to wood, brick, cement rendering and rigid plastics. Polyflex will also seal around pipe work and bottom drains. When liners are tucked into brickwork it forms an excellent sealant since it allows for movement. Polyflex is supplied in a cartridge and is easily applied with a mastic gun or similar application tool.
