How to Apply Acoustic Sealants
If you live in a home with very thin boards, then you may find that you need to add a layer of acoustic sealants in order to soundproof your walls from the next door neighbors. In some high-rise areas, or in modern buildings, the partition soundboards can completely fail to defend you from the sneezes, music, and even conversations of neighboring people, and you may feel that you need to completely seal the edges of the board using one of the range of acoustical sealants available. Applying these sealants is not a difficult job, and you can get it done quickly and easily if you follow some basic guidelines for getting the job done.
Step 1 - Prepare the Area
In order to make sure that your sealants stick fully to the place where you are applying them, you will need to prepare the wall or dry wall board by making sure that it is completely clear and free of dust. Clean the entire surface of the wall using a duster, and then wipe it over with a sponge dipped in some soapy water. Make sure that there is nothing else on the front of the wall, and then leave it to dry. Give a quick run over with a dry cloth before you begin to add the sealants the following day.
Step 2 - Add the Sealant
The next step is to apply the acoustic sealant to the wall. Keep windows and doors open while you are applying the sealant, as you will need a good source of ventilation. You should also avoid allowing the sealant to get hotter than around 55 degrees, as this may cause it damage. Don't leave the sealant in the sun, and don't expose it to extremes of cold either. You will need to apply this using a caulking gun, which can be bought from local supply stores, and possibly even rented. When you have added the sealants to the gun, place your first bead of sealant to the board. You should be able to apply around 1/4 of an inch of sealant to the edge of the board or wall. You should not have a bead of more than half an inch in diameter, as this may cause the sealant to be too large to dry properly in the future. Allow the surfaces you have covered to dry fully before the room is used.
Step 3 - Finishing the Sealant
Once you have applied a series of beads to both sides of the board, you can then proceed to cover other areas of the room with sealant. Good places to use the caulking gun is on window frames and door frames, on any corners of the wall, and along the edges of pipes and light fittings. You should cover the entire outside of electrical boxes and circuits with the sealant.
