If your cinder block is outside, primer it first, then use oil base.
Scrub it with warm water and a sponge sander block.
No, it's not a latex base.
It's generally much better to use water base primer on drywall.
You have a contradiction ! - Latex primer CAN NOT BE oil based.
Just paint it on if the latex is adhering well.
Can you restate your question are you asking what is the latex paint or are you asking when was the invention of the latex paint.
Yes it will.
No, they will not mix,
Yes you can.
There are two main reasons:A bowling pin, at around 3 lbs. 8 oz., is much lighter than even the lightest bowling ball, while the opposite is true for a cinder block.In addition, the odd shape of the pin (with its small base and larger middle) brings its center of gravity up off the floor much higher than a cinder block of equal height. This makes the pin far more likely to tip over when struck.
It's primer made with a latex or acrylic base. You can use any kind of paint over this.
Yes, you can.
