Spray Paint Indoors
Can you use spray paint indoors? This might not seem like a common homeowner question, but it comes up more often than you would think!
You might associate “spray paint” with graffiti, but a surprising number of homeowners find themselves needing a can. Beyond the decorative repainting of light fixtures and furniture that you see on TV, spray paint delves into the world of specialty primers.
Speciality primers provide extra sealing before you repair damage, or finish knotty wood. So some cases where you would need a small amount of specialty primer are:
- you have a watermark on your ceiling
- there is an area with mold
- three knots showing through your stair stingers or door frame
- someone’s pet peed on the rug and it soaked through to the subfloor
In these situations, the amount of product in a spray can is more desirable then a quart or gallon of paint.
If you are painting a home that had smoke damage or a cigarette smoker then you are going to need a larger quantity and a quart or gallon size will be more appropriate.
Using the Spray Can
Spray paint cans have smelly solvent based products in them, and they also create overspray. So unless you are creating a Dexter like spray booth, using cans indoors is ill advised. But you can’t take your ceiling stain outdoor, right?
Don’t worry, we’ve got your back.
1: Get a container and a brush that you are willing to throw away after using.
To clean specialty primers you need specialty solvents, which are not great for the environment. On the other hand, dry paint is not an environmental hazard and can be disposed of in the trash. Our advice is to use disposable containers and cheap brushes, and simply dispose of them when they are dry.
2: Assemble all of your tools and product at the site that needs to be primed
These primers dry extremely quickly and if you take five minutes to prepare after step three, you will loose some of your product.
If you need a step ladder, or a drop cloth (these primers tend to be drippy so make sure you protect the areas around them even if you are not a painters tape user)
Your brush will also dry quickly, so unwrap the brush and have a piece of plastic wrap laying out to wrap it between coats.
3: Put on latex gloves.
When you use a spray can some of the product will get on the finger that is on the nozzle and as per step one, cleaning if off your hand is going to take a harsh chemical. When the project is finished remove the gloves and let them dry. You can decide if you want to reuse them or chuck them in the trash.
4: Go outside and shake the can as per the instructions
Some need to be shaken a lot. Don’t skimp on this step!
5: Spray the can into your disposable container
Holding the container away from you and making sure you are not downwind from it, spray the product into the container until you have the desired amount. The products tend to dry quickly so aim for what you would need for one coat, or no more then 1/4 of a cup.
6: turn the can upside down and spray until the vapour is clear –
This stops the nozzle from clogging
7: Brush on the paint, and wrap up your tools when you are finished.
I like to always make sure I have a thick enough layer on the surface before I lay out my brush to dry. Most areas that are using one of these specialty primers will need more then one coat, sometimes several.
Read the directions on the side of the can to see the recommended number of coats for your project and plan for that before you start.
