It is highly recommended to resort to a professional and reliable company that provides insulation services, because believe it or not, insulating your house can save you a great deal of money. Those high heating and cooling bills will be long forgotten after installing insulation. One of the most efficient and high quality types of insulation you can opt for is spray foam. You should do some research on the internet and look for the best spray foam insulation company in Toronto. Here are some common problems when spraying foam insulation that need to be avoided in order to benefit from the best results.
Spraying cold or hot foam
It is important to know that the foam should be at a very specific temperature the moment it is sprayed. If it is too cold, the foam will come out spongier and softer, leading to a reduction in hardener. The R value of the foam is reduced and this way the insulation is not of the best quality. One great method to warm up the kit is to place it in direct sunlight, but it should not be kept for too long. The foam should be warm to warm to the touch and not too hot. If it gets too hot, the foam will become flaky and crusty, which also results in a reduction of the R value.
Spraying with a clogged nozzle
Another common mistake that should be avoided is spraying the foam with a clogged nozzle. If this happens, it is highly recommended to replace the tip of the nozzle with another one, because otherwise the foam will not be sprayed in a regular and even pattern. When you start spraying the foam, you will notice that the pattern is quite even at first, but that it gradually declines during the process. This happens because foam is sticky and it tends to build up on the tip of the nozzle. If you notice that the pattern is not regular anymore, you can try either slightly rubbing the tip or replacing it with a new one.
Spraying too fast
When spraying foam, it is not recommended to move too fast, because you will only end up putting down about half inch of foam, which is not enough for proper insulation. Spray slowly and continue to move away as you spray. Do not forget that you have to apply another coat after the first one has dried out.
Another mistake to avoid when spraying foam is actually overspraying. You might be tempted to apply a thicker coat of foam from the very beginning just to make sure you properly insulate the house, but this is wrong. You should not stay for too long in the same spot, because this will not give the foam a chance actually to grow and install properly on the walls. If you apply another coat right after you have applied the first one, you will only end up losing nearly half of the volume of foam. Apply the right amount of foam to benefit from the best results.
