How to use this product
Thoroughly clean and dry surface from oil, dirt and grease with Mineral Turpentine firstly and then Methylated Spirits. Allow drying completely before applying silicone. If there is old silicone which needs to be removed, we recommend using SELLEYS SILICONE REMOVER, this ingenious product makes removing old silicone easy.
Ensure you tape both sides of the gap before applying the product. This ensures a neat finish and makes it easier to clean up.
Cut the seal at the top of the cartridge and cut the nozzle at a 45° angle, to the size of the gap opening. Fit the nozzle to the top of the cartridge.
Insert the cartridge into a caulking gun such as SELLEYS LIGHT SPEED Caulking gun. We recommend SELLEYS LIGHT SPEED Caulking Gun, as its new innovative pressure release design reduces the mess which results from run on and stress on your hands, which is critical if you are doing a lot of sealing.
Hold the caulking gun at a 45° angle. Press the nozzle opening against the joint, apply steady pressure to the caulking gun and extrude the silicone sealant forcing the sealant into the gap and move in a pushing motion, along the joint in one smooth action.
For a smooth finish, smooth with a finger dipped in mineral turpetine or for a professional finish use a paint scraper such as a 50mm ROTA COTA Soft Grip Scraper dipped in mineral turpetine.
Excess sealant must be cleaned up before the sealant skins in 5-10 minutes. Wipe excess away with a cloth dampened in mineral turpetine or use a SELLEYS Hand Kleen Wipe. Remove tape before the sealant skins. Clean tools immediately in mineral turpetine.
Avoid smearing on surrounding surfaces, see handy tip.
Sealant will cure fully in 72 hours. As this point, any unwanted sealant can be removed by trimming with a sharp blade but avoid undercutting the seal.
For aquariums, allow the product to fully cure for 7 days. Prior to usage, thoroughly wash out with water, drain and refill before introducing fish. Suitable for constructing and repairing small aquariums. The specialist design required for large tanks. Contact SELLEYS if unsure.

Handy tips
Tips for Using a Silicone Sealant on Glass

Ensure you tape both sides of the gap before applying the product. This ensures a neat finish and makes it easier to clean up.
The depth of the sealant should be no more than 10mm in joints. To fill larger joints use a suitable backing rod (such as closed cell polyethylene foam or similar), leaving the gap depth no larger than half the width of the joint.
When first applying product, extrude a small amount onto a piece of scrap material to ensure a smooth continuous flow of silicone sealant.
Remove the tape before the silicone sealant skins.
For a better finish complete painting prior to use of the sealant as it can not be painted over.
For a better finish, use a spatula dipped in mineral turpetine or detergent and water to tool off the sealant.
Work in sections that can be completed before sealant skins. Tooling off and tape removal must be completed before skinning occurs or a rough surface may result, so working in sections allows for a better finish.
Keep a pack of SELLEYS Hand Kleen Wipes handy to wipe up any spills and for cleaning any material off the skin before it cures. They are an easy and effective way to keep clean on the job.

Safety tips
Uncured product may irritate eyes. If in eyes, flood the eyes for at least 15 minutes and seek medical advice.

Keep away from children.

Storage and re-use
Store in cool dry conditions, below 30°C
The sealant should be used within 6 months after opening.
After use, keep the nozzle on the cartridge.
Silicone is a reactive product and is designed to cure once exposed to humidity. While the product may be stored for a few months once opened, it does have a limited shelf life. Storage in an upright position in a cool dry place is recommended to maximise the storage life.
If the sealant is going to be used again within a few days, leave the nozzle on and merely extrude approximately 2 cm of the product before storing the cartridge upright. This will cure to a plug which can easily be pulled out when required.
For longer storage periods, leave the nozzle on and place a piece of plasticene or Blu Tack over the end of the nozzle. Tightly tape a piece of aluminium foil over the whole nozzle to exclude any air.
When you want to re-use the product, simply take off the foil and plug from the old nozzle pull out the excess silicone from the nozzle with a corkscrew, then re-pierce any cure at the tip of the cartridge and re-use.
If cure has taken place into the cartridge, the product is unlikely to be in a useable state and should be discarded.
