*** CHALKING

Chalking is usually caused by using a poor quality paint, or by waiting too long between paintings.

Solution: Wash chalk off with a solution of ½ cup detergent in a gallon of water; rinse well.  After residue has been removed, reprime surface and repaint with chalk resistant Paint

*** NAILHEAD STAINING

Steel nailheads can rust from moisture in the wood or from improper patching with putty and primer when first painted.

Solution:  Replace rusted nails with a good quality, zinc-coated type.  For those that can’t be removed, sand rusted nailheads down to bright metal and countersink.  Spot prime nailhead with Oil Primer Sealer and after drying use an  wood putty or suitable caulking to over-fill (slightly) nailhead area.  Finish by sanding filled areas flush with surface and spot prime prior to painting.

***  MILDEW

Mildew looks like conventional grime, but is actually a living fungus which eats proteins and nutrients contained in paints and substrates.  If you are not sure whether your problem is dirt or mildew, place a spot of bleach on the affected area.  Only mildew will react by whitening Some of  of Paint contains agents which inhibit the growth of mildew on the surface; however, if mildew is present prior to painting, growth may still occur.

Solution: since moisture is essential to the growth of mildew, you must take preventive action against moisture to avoid recurrence.  To clean mildew from surface, use a solution of 1 quart household bleach in 3 quarts of water making sure skin and eyes are protected.  Rinse with clean water and allow to dry thoroughly.  Scuff sand glossy surfaces.  Sand down badly weathered areas and spot prime.

*** BLISTERING

Blisters are small pockets of vapor that form beneath paint film, caused by painting in direct sunlight and over hard or glossy surfaces.  They are also caused when water, trapped inside paint, vaporizes and bubbles on exposure to intense heat from the sun.

Solution: Break open a blister.  If bare wood shows, moisture is the problem.  If a sound layer of paint is under the blister, it is caused by heat.  In either case, blisters should be scraped, sanded and primed Oil or Acrylic Latex Primer Sealer prior to repainting with Premium Plus House & Trim.
