    How to use a sealant gun


    Summary: Learn how to use a silicone sealant gun.



    Sealants are used for filling joints and bonding various components within a house. Such uses include filling in the edges of architraves or skirting boards, window and door frames, or for sealing around a bath or other similar places.


    Using a silicone sealant gun

    Sealants are an essential adhesive, used widely in DIY. A gun is used to apply the adhesive, which is a simple process; however it must be done correctly in order to be effective.

    • You will firstly need to open the tube of sealant. This can be done using either sharp scissors or knife. Cut the end of the nozzle off where marked. If there is not a manufacturer’s mark, then cut the tip at a 45 degree angle.
    • Insert the tube into the gun and practise using it on some old newspaper. You will want to get the hang of applying the sealant in even quantities. Be careful not to squeeze the trigger too hard or the sealant will shoot out. Be gentle and increase pressure gradually.
    • When you know how to use the gun sufficiently, inspect the area you want to use the sealant on and make sure it is completely clean. Any dust and dirt could affect the ability of the adhesive to bond properly.
    • Place the nozzle of the tube against the surface of where you want the adhesive applied and gently squeeze the trigger as you have practised. Holding the gun at a 45 degree angle, move it along the length of the area you want bonded once the sealant starts to come out of the nozzle.
    • When you have finished and want the sealant to stop coming out of the gun, press the release catch at the back which will stop all pressure on the tube.
    • You should check the job to make sure you have used enough sealant. It is usually best to have a little too much than not enough, as sealants need to fill the entire area that you are sealing or bonding. Any excess can be wiped away with a damp cloth.
