What is the recoat time for Mad Dog Primers?

Under ideal conditions, 1 to 2 hours for recoating with primer or applying a topcoat. A good rule of thumb to follow: when the primer feels tacky to the touch, without leaving any residue on your fingers, it’s ready for recoating.

It is recommended that you topcoat this primer within 5-7 days so the paint properly bonds with the primer.

Why does the primer stay sticky?

Mad Dog primers are made with patented resins that have high adhesion and bonding properties. They remain tacky to the touch when dry. That tackiness is what helps the topcoat of paint or stain to adhere and crosslink with the primer.

Can I use a flat sheen paint on top of a Mad Dog Primer?

Yes, in most cases. High quality flat 100% acrylic paints from paint manufacturers like Sherwin Williams, Benjamin Moore, PPG, California Paints, and others, perform exceptionally well on top of Mad Dog Primers.

If you are working with paint and primer that you haven’t used together before, it is recommendeed to do a test to ensure compatibility before progressing with you project.

If in doubt, try a 2 ft sq test patch. Apply the Mad Dog Primer, let it dry. And then apply your desired flat 100% acrylic topcoat. Let it cure overnight before proceeding.

Can I use an oil based paint or stain on top of a Mad Dog Primer?

No, oil or alkyd based topcoats dry harder and more brittle than Mad Dog's flexible primers. An oil based product will most likely crack on top of a Mad Dog Primer and cause problems. It is only recommended to use high quality 100% acrylic latex paints and stains in conjuction with Mad Dog Primers.

Can Mad Dog primers be tinted?

Yes, with up to 4 ounces of tint per gallon.

What is the best way to apply a Mad Dog Primer?

Brushing, rolling, or spraying through an airless sprayer, are the best methods for applying a Mad Dog Primer.

If you're spraying it is highly recommended to backroll to make sure the primer covers and adheres to all the nooks and crannies in the substrate you are priming.

If you're applying with an airless sprayer, a 517 or 519 or 617, if you want a wider spray pattern.

Mad Dog Crack Fix

I’ve used this before with our plaster wall house and think it really improves the look and durability when used before regular paint. I couldn’t find Mad Dog locally and was very pleased with how quickly it shipped.
