Ventilation for Spraying


There are several reasons for venting the room when spraying paint.

1. Overspray gets everywhere and sticks to surfaces causing damage to painted and unpainted surfaces

2. Too much overspray build up in the air can become quite dangerous and explosive.  Even though today's modern materials have much less solvent and are less volatile they are still more dangerous when allowed to build to a high density.

3. Allowing too much overspray in the air will inhibit your ability to see causing poor quality repairs .

4. Higher concentration of toxins in the air can more easily cause health problems from exposure.

5. Venting is usually not that expensive on the hobbyist level and is usually only a small percentage of the cost of an overall restoration.
 


For most spray painting operations the air in the spraying environment should be changed every one to three minutes.  This recommended exchange of air can be prolonged for the occasional painter but it should still be entirely vented in about five minutes.

In order to calculate the time it will take to vent the room you should multiply  the length X width X height to get the cubic feet divide by the number of minutes you want to exchange the air.
