Mad Dog Dura-Last Primer

Mad Dog

Gray (When Dry)

Mad Dog Dura-Last Primer(MDPDL) is an exterior water-based, non-toxic, stabilizing primer with a light gray 35% solids formula. Dura-Last Primer is designed for cost conscious projects which do not require tannin or rust blocking qualities. Dura-Last penetrates and stabilizes and prepares peeling paint, cracking stucco, wood, concrete surfaces. Using MDP effectively doubles or triples the job life of many projects.

Double or Triple the job life

Here are some practical examples of doubling or trippling the life of a job.

Repainting walls
Normally repainted every 6-8 years. With Mad Dog Primer the project can last 10-20 years with some touch up

Deck Railings
Normally refinished every 1-2 years. With Dura-Last primer the coating can help it last 3-6 years.

Using Dura-Last brings the maintenence cost of any project down significantly. When the surface does finally need to be recoated surface prep will be minimal before recoating.
