"I just bought Markal stick paints and they don't paint, why?"
Nothing happens to them. Markal Paintstiks have a thin film that covers them, prevents them from staining and also from drying out. To get them to paint, simply remove the film with a scalpel, vegetable peeler, or small knife to expose the fresh paint underneath.
"Are Markal paintings permanent? Can they be washed?"
Yes, they are permanent.
Let it air dry on porous surfaces and that's it.
On fabric it is necessary to allow it to air dry and then heat-fix the paint with an iron or in a clothes dryer. Once heat set, the paint is permanent and the fabric is washable. Note: do not dry clean fabrics painted with Markal. Dry cleaning fluid is a solvent and will dissolve Markal colors.
"¿Cuánto tardan en secar las pinturas Markal?"
On textiles, if you have painted using stencils, the paints will be ready to heat set within 24 hours, unless you have applied very thick layers of paint. To check if the paint is dry, rub with your finger over a small section; if it does not stain, the fabric is ready to heat set.
With any direct application technique they take longer to dry. Allow three to five days for the paint to dry. Up to seven days if you do multiple layers or during humid times of the year.
"How do I store my Markal Paintstiks?"
The thin outer film is self-generating the day after using the bars. This thin layer prevents staining and also drying out over time. Simply store the paintings in a plastic box, plastic bag, or whatever container you have on hand that will keep them separate from other products.
"How can I heat set the Markal Paintstik paint?"
Use an iron: preheat to the appropriate temperature for the fabric. Lay the fabric (paint side down) on a piece of parchment paper or brown kraft paper. Press for 10-15 seconds and do not steam. The greaseproof paper or kraft paper will collect excess oil and pigments, which prevents staining of the ironing board. Use a clothes dryer: After the paint has dried, put the fabric in a clothes dryer on the hottest setting for 30-45 minutes. Do not put the freshly painted fabric in the dryer.
"Do I have to heat set my tapestries?"
If you are painting fabric for a tapestry, there is technically no need to heat-set the paint. It is enough to let the paint dry. Heat speeds up the end of the drying process and is recommended for anything to be washed but there is no compelling reason to heat-set fabric to be used in tapestries.
"Can I use Markal Painstik colors on all types of fabrics? What about synthetics?"
The type of fiber is not going to be a problem with Markal paints. When a fabric is dyed, a chemical bond is formed between the dye molecules and the fibers. That is why a different type of dye is needed depending on whether the fabric is made of cellulose fibers (cotton, linen, rayon) or protein fibers. When painting a canvas, adhesion is strictly mechanical. The paint adheres to the surface of the fibers instead of forming a chemical bond. The only fabrics that cannot be painted are those that have been chemically treated to be stain resistant. We recommend washing the fabric before painting with a normal detergent without fabric softener.
"How much can I paint with a Markal Paintstik stick?"
Much! Two to three meters can be covered before completely finishing an entire 50 ml Markal Paintstik stick.
"How old are Markal Paintstiks paint sticks?"
Markal Paintstiks paint sticks have a very long service life. According to the manufacturer's instructions, they will begin to dry two years after their manufacture. We have some Markal bars from before 2000 that are still working in perfect condition - the film on them is a little thicker but that's it!
"What can I do so that the stencil I am using does not move?"
You can apply a repositionable adhesive to the back of the stencil. We use Wega brand spray adhesive. A small amount of adhesive is applied to the back of the stencil, you wait 30 seconds, check that the touch is like Post-It and finally you stick it to the surface to be painted. When you finish painting, remove the stencil and you will see that it does not leave any residue on the painted surface.
"I am using stencils and some of the images have to overlap. After painting the first image, can I immediately move on to the second image or should I wait for it to dry?"
You can immediately place the stencil in the next position and continue working. You just have to put a piece of plain paper over the stencil to prevent the paint stuck on the iron from staining. When working "wet", without waiting for the paint to dry, you can see some mixing of colors as you apply the paint with each stencil. If you don't want the colors to mix, you can wait 24 hours between each application. You can also use a hot air gun (a hair dryer is not enough) to quickly form a film on top of the paint. Heat is preferably applied to natural fabrics, synthetics can melt.
"How can I remove the adhesive spray from my stencils?"
You can use any solvent sold in paint stores.
"How can I clean my stencils?"
There are several things that can be done to keep stencils clean ...
1. Clean the stencils as you work. Have a tissue handy. After using the stencil, place the stencil on a microfiber cloth or tissue and gently wipe the paint with another cloth or paper towel. Clean both sides of the stencil.
2. Spray some thinner on the stencil and wipe clean with a cloth or paper towel. This is very useful if you have paint build-up on your stencil.
3. Clean with a little soap and water.
