This is to help clear up a common misconception about mixing ratios which can lead to disastrous results. Normally, the ratio is given in a format like this-- 2:1:1,which translates as 2 parts paint,1 part hardener,1 part
reducer. NORMALLY hardener(hardener and activator are the same thing) is
listed before the reducer but you must verify that by reading the tech sheets. That way is self explanatory, it's when the ratio is given as a percentage that the confusion sets in.
A 50% reduction does not mean half and half ,that would be 100%(1:1) reduction,50% translates to 2:1,the percentage is a percentage of one part,NOT a percentage of the contents.If the ratio is given as 100% paint, 50% hardener, 25% reducer then that translates as 4:2:1,i.e. 4 parts paint,2 parts hardener,1 part reducer
Mixing ratios are very important and should not be ''eyeballed",i strongly
suggest using a clear mixing cup with the ratios already marked on the cup.
In a pinch you can use a straight sided can with a flat bottom and make a stick to get your ratios.
take a wooden paint stick and a tape measure, now mark off 1/2 inch
increments. Now number each space as such:
now if you have a ratio given as 4:1:1 then you will pour paint to the line above the 4,you will add activator to the line above the 5 and reducer to the line above the 6.
Remember, you should always wear a respirator when mixing the paint or primer as the chemical reaction of blending the components is more dangerous than the mixed component you are spraying.
