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, such as a ROTA COTA Sanding Block Medium/Course grain, as the silicone will adhere more readily to a scratched up surface.
• 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 under cutting the seal.
• Protect from water contact for at least 24 hours after application. Under optimum conditions the Paint Over Silicone with normally cure in 24 hours and continue to strengthen over 7 days (longer in damp conditions).
• Paint within 48 hours. Some gloss paints don't adhere to the silicone, so paint first with an undercoat.
• To ensure you get a professional finish ensure you paint with a good quality paint and paint brush. Painting with a good brush ensures the finish and durability of the paint is increased. We recommend a 50mm SELLEYS SPIRIT Edger Brush, as the cut angle of the bristles takes the work out of applying paint.

Handy tips

Tips for Using Paint Over 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 use a spatula dipped in detergent and water to tool off the sealant.
• Allow the surfaces to skin prior to painting, which is approximately 30 minutes. Protect from rain until firmly skinned. Allow for longer skin and cure times in damp conditions.
• Some water based under coats & flat paints may crack on drying. To reduce this effect allows the product to cure for 24 hours in small gaps or 48 hours in larger gaps before painting with such paints.
• To improve the paint finish, wipe the sealant with detergent solution immediately before painting.
• Avoid smearing sealant on the surrounding surfaces as this may effects its paintability.
• Paintability reduces after 48 hours. Paintability can be improved by over coating exisiting sealant with a fresh layer of 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.

• For further detail on the safe use of this product, please refer to the Material Safety Data Sheet, which can be downloaded from this site.
• 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 air.  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.
