How to Pull Off DIY Spray Foam Insulation

spray foam insulationWe are always on the look-out for ways to save cash on home repairs and maintenance by DIYing it. DIY kits and tips can save immense amounts of money, time, and even the stress spent waiting for tardy contractors and repairmen.

Home insulation is a really important part of home maintenance, keeping a house cooler in summers, warmer in winter and which saves on heating and air conditioning bills.

Traditional forms of insulation can get really expensive, and nearly always require professionals for installation and removal. Skilled contractors can be expensive, and take time to properly insulate a house.

DIY spray foam insulation, also known as SPF (Spray Polyurethane Foam), is a continuous insulation and air-sealing barrier for the house. The coolest thing about it is that it can simply be sprayed on!

How to pick the right DIY insulation foam spray for your house

While buying an insulation spray, you need to ensure that the material, spray container and size you pick is optimum for your house. DIY spraying is best for smaller homes, or when you have less space to cover. SPF is the best insulation material available.

The nozzle of the spray bottle you buy should be large enough to avoid clogging, and small enough that you can handle the flow easily.

Here’s all you need to know about DIY spraying your house in three easy steps.

1. Read the manual well.

Make sure you read through all instructions thoroughly and follow safety warning labels included with the kit. Foam is dangerous when inhaled, so make sure to keep your safety glasses, gloves and a face mask handy.

For easy cleanup, you can place a newspaper on the floor before starting to catch any spills.

Remember: insulation is flammable. Keep away all items that could lead to an ignition, including lighters, bulbs and electric appliances.

2. Practice spraying before you start.

Spray foam insulation tends to expand after spraying, so it is a good idea to practice a bit, before you point the nozzle towards your house. Practice spraying into a garbage can or empty box.

Spray foam insulation can often expand up to 100 times of its initial volume in a matter of ten seconds, so be sure to practice before. The foam also gets really sticky before it hardens.

3. How to apply.

Before you start spraying, remember to:

  • have all your safety paraphernalia in place
  • keep a rag at hand to clean up spills
  • make sure you’re not spraying on anything flammable

You should mist the area with water before the spraying process, to make things softer and easier to adhere. This also helps speed up the curing process.

Spray using smooth, long strokes to cover the desired area. Remember to leave at least 50% of the space free, for the foam to expand. If the spraying nozzle gets clogged with foam, trim the clogged part away and continue spraying.

Once you’re done with your DIY spray foam project, you’ll have a sealed air-tight fortress, much more immune to temperature fluctuations. Spray foam insulation is great for reaching into and closing up any small nooks and crannies.

You can bring your heating costs and electricity bills down by up to 40%, using spray foam insulation. Happy spraying!
