A general rule of thumb with tinting lam resin, the more you put in the darker, richer and more opaque the color will be.
You really dont need to add much to get a light transparent tint. Maybe half a tablespoon. Start from there and keep adding whilst testing as you go for color and transparency. I like to get a scrap of foam and a bunch of 2: square cloth scraps and simply lam the resin after each time you add more tint.
With paint, thin it just enough to get it through the gun.
Here’s a useful tip: when you have thick paint and you want to thin it out, START with a certain amount of thick paint, then add the thinning medium a little at a time.
For example, if you use Liquitex out of the tube, it’s a thick paste. Begin thinning with just a little purified water, or Future Acrylic Floor Finish. Mix that thoroughly until you have a smooth, slightly thinner paste. Then add a little more water or Future, and mix that until it is smooth. Keep going until you get it thinned out so it goes through the gun.
Same principal applies with thick, liquid paints that need thinning. A little at a time. Thinner into paint.
Very Important. After mixing, pour the paint through a filter into whatever CLEAN container you will be storing it in. For the money, panty hose are the best. Use the legs, tie a knot in the end and cut off 2" to 3", drape it over the container and pour. Doug
No apology necessary about the pigment/tint mix up. I had the same confusuion…the only difference really is that tints will be more transparent, while pigments tend to be more opague. If you were hoping for a transparent look, just be careful not to over pigment the resin. I am not an expert, but if you post your ideas for the resin work, some of the pros on here will definetely be able to give you some really expert advice on how to acheive the look you are after. Good luck!
