G4 Pond sealer
G4 is a single part air drying polyurethane finish which is used on rendered surfaces in order to seal out lime and provide a gloss or satin finish to pond walls and floor. It is simple to apply with brush or roller and is normally applied in two or three coats. 2nd and subsequent coats must be applied whilst the previous coat is still tacky. When using coloured G4, use two coats of clear followed by two coats of colour to provide the necessary depth of colour. Should only be applied to clean, dry surfaces. Clear - cost per Square metre approximately £17.50. Cost per square metre of coloured G4 finish is approximately £25.50.

Aquacote
Aquacote is a superb two part voc free epoxy finish comprising a clear basecoat and coloured top coat (black, blue, grey, clear or green). It can be applied with a normal paint roller in stages (no need to finish the entire job in one go!) and will last a lifetime. Once applied is completely unaffected by water even when wet so will cure completely normally underwater. Acts as a water proofer and sealer, gives a fantastic finish as good as fibreglass and at a quarter of the cost, and with none of the risks of fibreglass toxicity. Completely fish safe, pond can be filled and fish added within 48 hours of application. Can be applied to damp surfaces. Suitable for a wide variety of surfaces including metal, cementitious renders, brick, stone and concrete. Full application instructions are provided with this product. Aquacote would cost approximately £15.50 per square metre of finish using the recommended two coat system (1 x base coat and 1 x top coat). A 2kg tub will cover up to 10 sq. meters (for the clear product) and up to 8 sq. metres (for the colour product). Coverage is dependent on the type and porosity of the surface to which the product is being applied.
Examples of the outstanding finish achievable with Aquacote (above and right). One 2kg pack of Aquacote will cover 5-10 sq metres depending on the surface being covered. The Clear product is somewhat thinner in consistency and will generally cover a larger area.
We recommend Clear as the best primer/base coat Normal application : - one coat of base coat, then one coat of top coat. Further coats can be added if required.
Surface preparation. All surfaces recommended as suitable for application should be as dry as possible and free from all loose materials and grease, oils or other chemicals. Rendered surfaces must be allowed to cure fully before application. Provides excellent finish to fibreglass surfaces instead of normal gel coat - avoids any risk of polluting water with styrenes so commonly found with fibreglass finishes.

Plastic reinforcing fibres.
Used to reinforce and waterproof sand/cement render and concrete. These are not fibre glass strands, unlike other materials, but plastic fibres. They are safe and easy to handle and gloves are not required. Widely used in civil engineering construction projects for years, because concrete and render reinforced with plastic fibres is ideal for damp or wet construction projects - such as ponds. Massively increases strength of applied renders, make structure waterproof and helps avoid cracking. One bag of fibres is sufficient for 2 full mixes. We suggest a full mix in a barrow type mixer is 4 buckets sand to 2 buckets cement. 2: 1 mix. plus one half bag of fibres.
| Pack Size | Price | |
| 0.9kg | £17.50 |
The recommended mix is one part soft sand to one part sharp sand to 1 part cement. Add fibres to water in the mixer first then add the sand and cement to ensure they are well distributed. There is no need to use plasticiser, but one can add a good waterproofer such as Sika. It is recommended that one coat of render is applied only to improve bonding. The render can be finished with a plastic float and/or sponged finished. Once cured, any fibres protruding from the surface should be burnt off using a hot air gun. The resulting finish is then perfectly ready for your chosen paint finish (see above) or for fibreglassing.
