Gold Label Pond Paint Black

G4 Black Pond Sealer

G4 Black Pond Sealer is a moisture cured polyurethane which forms a non-porous seal on concrete rendered ponds, G4 pond sealer uses the moisture in the air and the render to harden, G4 pond sealer can be applied to slightly damp surfaces, but it is important that the render is sufficiently dry to be porous so as to enable the first coat of G4 pond sealer to bond and obtain a mechanical grip, G4 pond sealer can be applied in poor weather conditions, high humidity and at temperatures down to zero degree’s.

Koi Pond Construction Materials

As a general rule the pond should be constructed to be structurally sound since the G4 pond sealer only provides the waterproof seal, on no account use a P.V.A based sealer to seal or prime any surfaces, these materials can contain ammonia and also stop the G4 pond sealer from adhering to the render.

Ponds will normally be constructed with either brick, lightweight block or concrete block and then rendered, it is not necessary to add waterproofing agents to the render mix as this will increase the density of the render and can inhibit G4 pond sealer penetration, if a waterproofing agent has been used, simply rub down the surface with an abrasive to obtain a key.

If a fibre is used to give strength to the render it is necessary to burn off or sand down any fibres that are on the surface, as any fibres that protrude will cause leakage, G4 pond sealer will not bond to the fibres.

The cement render should be trowelled to an even surface but not to a smooth dense plaster like finish since this prevents the penetration of G4 pond sealer, new render should be kept damp for the first three days and then allowed to harden for 21-28 days depending on conditions.

G4 Black Pond Sealer is an excellent sealer for brickwork, but below the waterline the brick should also be rendered. The reason is that while the G4 Pond Sealer is able to seal hairline cracks G4 Pond Sealer is not capable of bridging larger joints, cracks or holes.

G4 Pond Sealer Method of Application

Apply the first coat of G4 pond sealer by brush, a roller can be used but it is necessary to avoid puddling of the G4 pond sealer on the base, it is best to use a brush, allow the first coat of G4 pond sealer to become finger tacky ( like cello tape ) or dry enough to walk upon carefully, approximately 45-60 minutes depending on humidity, then apply 2nd coat of G4 pond sealer, when second coat of G4 pond sealer is finger tacky apply third coat of G4 pond sealer, no longer than 4 hours should pass between coats, if a colour is used, then use 2 coats of standard and 2 coats of colour, G4 pond sealer is mechanically hard after 24 hours but must be given 72 hours to chemically cure, after which the pond can be washed down with plenty of water, drained, and can then be filled.

We strongly recommend that you mix Black Knight Wizard Fibre or some similar fibre into the render mix. This will help prevent the frost cracking the render in winter and give additional strength to the structure.

G4 Pond Sealer Clear Application

Apply first coat of G4 pond sealer Clear by brush, a roller can be used but it is necessary to avoid puddling of the G4 pond sealer Clear on the base. Allow first coat to become finger tacky or dry enough to walk carefully upon, approximately 45-60 minutes depending on humidity, then apply the second coat of G4 pond sealer Clear. When second coat is finger tacky apply Third coat. No longer than 4 hours should elapse between coats. Normally 3 coats of G4 pond sealer Clear is sufficient to build a continuous surface film but on very porous substrates a 4th coat of G4 pond sealer Clear may be required, apply as instructed above.

G4 Pond Sealer Colour Application

The system is slightly different. When using G4 Pond Sealer Colour the first two coats must be G4 Pond Sealer Clear. This is because G4 Pond Sealer Clear provides the maximum non-porous seal and adhesion.

Follow the application instructions as detailed for G4 Pond Sealer Clear but the last two coats will be G4 Pond Sealer Colour. G4 Pond Sealer is mechanically hard after 24 hours and workable on some 6 hours after final application. However, 72 hours must elapse for full chemical cure, before washing down the G4 Pond Sealer with copious amounts of clean water. This water should be drained off. The koi Pond can then be filled. Consumption of G4 Pond Sealer will vary slightly according to the porosity of the substrate.

G4 pond sealer Clear – 3 coats = 550g per sqm for the three coats (approximately 185ml per squ. metre)
G4 pond sealer Coloured – 2 coats of Clear = 410g per sqm for 2 coats (approximately 205ml per squ. metre)

G4 Pond Sealer is available in Standard Clear, Black and Green.

If rain is expected make provision for covering the coated area, since water can damage the G4 pond sealer during the curing process. As soon as it is superficially dry water should not affect G4 pond sealer

Gold Label Pond Paint Clear

This unique paint is designed to effectively seal and re-paint the concrete lining of your pond. It works using only 2 coats (on smooth surfaces) without needing primer, and as it is water based can be applied to damp surfaces. This means it is also less toxic than traditional pond paints.  It has coverage of 6-8 m2 which also means with 2 coats used (on smooth rendered concrete) it is far more cost effective than the typical pond paints out there. With a second coat application time of 6-48 hours and such ease of application, professional pond builders are choosing Gold Label Pond Paint every time! It comes in a variety of colours and sizes, is easy to mix and apply, and dries after 6-8 hours (full cure 3-7 days). The paint also works on other surfaces such as: blocks, brick, tiles, fibreglass and plastic. It should last approximately 5-10 years, giving you a fresh look to your water tight pond for years to come!

• No Primer Needed
• Works on damp surfaces
• Easy to apply with brush, roller or spray.
• Water based, therefore easier to clean & less toxic.
• 2 coats only (on smooth surfaces)
• Quicker pond refill than single pack paints
• Coverage of 6-8 m2 per litre
• Comes in recyclable packaging

DO NOT APPLY IN TEMPERATURES LOWER THAN 10°C OR OVER 25°C

Prep your pond: Make sure the surface is clean and dry and free of any imperfections/cracks etc. Should you find any cracks fill where appropriate with Gold Label Pond & Aquarium Sealer. For large cracks V out the crack to approximately 10mm, make sure the surface to be bonded is solid & dust free, prime the surface with PVA (follow manufacturer’s instructions), then fill with Gold Label Pond & Aquarium Sealer. 

Prep the paint: Please note: Although Gold Label Pond Paint is much safer than normal resin systems; it is recommended you should avoid contact by using a barrier cream or gloves. Please find the link to our gloves here. Any splashes should be washed off with soap and water.

• Your paint comes in 2 sections, the hardener in the top and the paint in the bottom. Prior to adding the hardener, thoroughly stir the paint. Add the hardener to the paint in the bottom pot and mix thoroughly for a minimum of 2 minutes (VERY IMPORTANT). Once mixed, the paint is usable for around 1.5 hours in ambient temperatures. (Over 20°c the timing will be reduced.)
• Once mixed, apply the paint by brush, roller or spray, ensuring that the coating reaches all corners, nooks & crannies etc. Apply a minimum of 2 coats (the 2^nd coat can be applied once the 1^st coat is touch dry (approx. 6-8 hours at 20°c) This applies to any subsequent coats). The paint will cure hard in 12 hours, and fully cure in 3-7 days depending on atmospheric conditions. Once fully cured, wash the surface completely and allow to drain before refilling to use once again. B: Leave for 24 hours and if there is any residue on the surface, skim off before adding any livestock.
