How to use this product
- Throughly clean and dry surface from oil, dirt and grease with Mineral Turpentine firstly and then Methylated Spirits. Allow to dry completely before applying silicone. If there old silicone which needs to be removed, we recommend using SELLEYS SILICONE REMOVER, this ingenous product makes removing old silicone easy.
- We also recommend sanding the surface back with a good quality sanding block.
- 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.
- 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 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. 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 under cutting the seal.
Handy tips
Tips for Using a Brick & Concrete Silicone Sealant
- Ensure you tape both sides of the gap before applying the product. This ensures a neat finish and makes it easier to clean up.
- 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.
Safety tips
- Uncured product may irritate eyes. If in eyes, flood the eyes for at least 15 minutes and seek medical advice.
- Avoid contact with skin, if contact occurs, wipe off immediately and wash with detergent. It may irrtate sensitive skin.
- Avoid breathing in vapours.
- Ensure you use a well ventilated area as product releases methyl ethyl ketoxime while curing.
- For advice, contact a Poisons Information Centre (AUS 131 126; NZ 0800 764 766) or a doctor.
- 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 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.
