stains from water, smoke, ink, pencil, grease, etc. with fast drying primer.
Always wash surface with an appropriate cleaning solution, or solvent. Remove as much as possible
of any unsoundly adhered coatings. Sand any remaining paint film edges to desired smoothness.
Sanding can be done to a desired smoothness before applying primer. Primer is not sandable after
applied. Bare wood exposed for more than 4 weeks should be lightly sanded or abraded to remove weathered
wood fibers down to a pink color.
Remove mold and mildew before painting with a solution quality biocidal/ mildewcide
wash. Rinse well. Always wear protective clothing and goggles to prevent eye and skin contact
with bleach. Do not mix ammonia or any other chemical with bleach solution.
Apply when air and surface temperature is between 50 and 90 F (10 and 32 C) and
relative humidity is less than 80%. Substrate moisture content should be approximately 15%.
Never apply MDP if weather conditions will not permit drying before rain, dew or freezing.
Do not apply in direct sunlight or on surfaces with a temp of 90 F / 32 C or higher.
Cool temperatures and/or high humidity can retard drying and curing. Allow product to dry
overnight in these conditions. MDP normally cures within 7-14 days. Rainy Weather: If MDP does get wet,
allow MPD to dry, inspect affected areas, touch up and repair/reprime as needed, Then continue painting.
MDP’s secret of success is its glue like grip and flexible strength. As MDP remains
flexible, use only (Top shelf) high quality 100% acrylic (flexible) exterior latex paints and solid latex
stains. Some flat paints will claim 100% Acrylic, but, the resins within the paint are quite brittle and
can cause a crazing and crackling effect after a few days. If glossy paints are desired, the 1st coat over
MDP must be a satin/semi-gloss followed by the glossy paint. This will result in a true glossy finish.
Test products you have not used over Mad Dog to confirm compatibility. Topcoat within 5 days. If it
rains and you exceed the top coat within 5 days rule, allow the surfaces to fully dry, check and touch
up damaged areas, and continue painting. Please call the manufacurer's tech line to discuss which flat paintsare approved as the first coat over MDP. 507-645-7431
Prepare substrate, apply MDP and top coat for desired performance on small area several
days before proceeding with entire project to be assured of desired effect desired.
Flashing and Sheen Variation Concerns:
Spot painting is recommended over the primed area before apply the first coat of paint to avoid flashing.
This is especially true of areas which are mainly spot primed; we recommend priming entire
surfaces to reduce this common problem. Test for desired results and let dry overnight before
proceeding with the entire project.
Cold Weather Application Tips:
During cold weather conditions with sudden temperature drops or with temperatures hovering
between 40-55F degrees, apply MDP in the morning and let it dry during the day. Wait until
next morning to apply top coat. Always stop work well before the end of the work day to
allow all products to set up before nightfall and temperature drops.
Rusty Metal and Tannin Bleed Problems: Mad Dog Primers is designed to stop light to moderate
rust and tannin problems such as rusty nail heads and railings. Apply 2 coats of MDP.
Let product dry between prime coats. Allow to dry overnight before painting.
Stabilizing Stucco and concrete cracks:
MDP is ideal for stabilizing hairline cracks. After preparing surface brush or roll MDP
into the crack or unstable area. Allow area to dry overnight. Be careful not to
apply MDP or topcoat on too heavily on rougher surfaces as it could crackle / mud crack during the
Hard to penetrate surfaces:
To assist penetration of primer into hard finishes such as southern yellow
pine, oak, concrete, stucco and plaster that consistently peels, MDP many be thinned s
lightly with 1-2 OZ. Per quart . Let area dry and apply a second coat of full strength MDP.
Application Methods –
Shake or stir before using. Do not thin under normal circumstances. Apply
with brush and/or roller or airless sprayer. Back brush or roll to work product into cracks and edges
of old paint and also into new and unpainted surfaces.
Airless Sprayer – Use .015”–.017” tip @ 1800–2200 PSI.
Product can also be splattered on the surface with minimal overspray and product
lose by reducing the pressure of your airless sprayer. Back roll / brush MDP into all surfaces.TINTING:
Product may be tinted up to 4 oz. per gallon of universal colorant. Use 1/2 quart formula
per gal tinting formula. Backfill with white when appropriate.
Because MDP is a clear base it will not tint opaque; it will be a more transparent look.
Dry time is normally 1 hour to the touch and recoat in 2 hours. Product applies milky
white and dries a clear green.
CLEAN UP: clean up with soap and water after use. Clean spills and spatters immediately with
soap and water. Disposal – Dispose of unused or unwanted product in accordance with local laws regulating
Store between 40F–90F. Keep from freezing or excessive heat.
