A note about my experience on screenprinting fabric with latex house paint…
I have been screen printing fabric with latex house paint for at least 3 years now. I have successfully printed a lot of things: napkins, pillow covers, curtains, t-shirts, tote bags, etc. I have exclusively printed on cotton, linen, and ramie, so I can not speak for synthetic fabrics.
I hesitated sharing this information because
1.) I wanted to make sure I knew what I was doing before putting it out there, and
2.) I was not sure how it would be received. In the end, I figured, if it can help someone else, it’s worth the risk of an internet backlash (ha-ha!)
I mostly print on things that will not get a lot of washing, but I have successfully machine washed, and hand-scrubbed fabrics that I printed. I have found that it is best to wait at least a week or so, to let the paint cure, before attempting any washing.
So obviously, you can not just glop on some house paint onto your screen and expect a good print. If that was the case, everyone would be doing this already. There are a few reasons this would not work out.
- Latex paint, used in its pure form, is too runny to be pulled through the screen.
- Latex paint, used in its pure form, dries REALLY fast, and will gunk up your screen.
- Latex paint, used in its pure form will leave a nasty haze on your screen, because it dries so quickly.
- Latex paint, used in its pure form dries stiff on fabric, leaving a not very pleasant ‘hand.’ Because of this, it also tends to crack over time and washings.
- Latex paint, used in its pure form, *may not be* wash-fast. This is debatable.
I call these ‘challenges to overcome’.
In order to make latex house paint suitable for printing, it needs to be ‘modified’ and ‘extended.’
Modifying & Extending the Paint:
Extending the paint simply means diluting it. This means that you are not using the paint at full strength.
You will be diluting the paint with a thickener. Wait, what? Yes, you are thinning with a thickener. It will make complete sense, I promise.
Latex house paint is highly pigmented and can stand to be thinned. Strangely, the color is not noticeably lightened in this process.
Extending the latex house paint solves challenges #1-4. Extending the paint will:
- Thicken, duh. Now you can pull it thru the screen.
- The extender used will slow down the drying process.
- Because it will now dry slower, there’s less likelihood of it drying on your screen, leaving the haze of color, and possibly blocking the holes on your screen.
- Because the paint has now been extended, it will dry on the fabric with a much softer hand, and the paint will not crack on your fabric with repeated washings.
Modifying the paint just means that you will add textile medium. This solves challenge #5. to make the paint wash-fast.
Now, I’m of 2 minds regarding washability. I believe that latex paint is washable on fabric.
Think about the last time you got paint on your clothes while painting. How hard was it to get that paint out? Extremely.
I add textile medium for extra protection. I do not really believe that latex house paint needs textile medium to be wash-fast.
On the other hand, I’m nervous to leave it out.
So you want to know what I use to extend my paint, huh?
I have tried a variety of products to make my paint screen-able. Here are the ones that I have tried.
- Shaving Cream. The cheaper the better.
- Clear, non-flaking hair gel. The cheaper the better.
- Unscented Lotion (yes, lotion) The cheaper (think dollar store) the better.
- Mineral Oil
- Permaset Aqua Print Paste
So there ya have it.
