1) The cost of paint just increased in the state of Oregon by 8%.
That means next time you decide to paint your home you will have to fork out extra dough for the project. Andruszko Painting will help offset these costs by giving you a 20-30 % contractor pricing discount on your next painting project.
2) Our NW weather patterns change from extreme to extreme, i.e. sunshine to cold nights in a 24 hour period.
What does this mean for the siding on my home or business?
The extreme temperatures cause the substrate (Hardie plank siding or cedar siding) swells and shrinks with the changing weather patterns. If you have an exposed substrate, right now may be the perfect time for Andruszko Painting & General Contractors to prep. it, and seal it before the cold winter sets in for the next 3-4 months.

Q: What is tannin? Do I have to worry about it?
A: Tannin is a natural extractive of Cedar, Redwood and most other dark woods. It migrates to the surface of the wood when water is present and leaves an ink-like, coffee colored stain or overall darkness on the wood after the water evaporates. Tannin bleeding is unsightly, but not damaging to wood or any coating on the surface. It can be removed with WOLMAN Cedar & Redwood Deck & Fence Brightener or All Exterior Wood Deck & Fence Brightener.
DEFINITION: Tannin (or Extractive) Bleeding: Redwood, Cedar and Douglas Fir are examples of wood species that contain naturally occurring, water soluble chemicals that tend to migrate to the surface with exposure to extracting agents such as water. After rain or heavy dew, coffee or tea-colored stains may appear on the wood surface. If the wood is coated, discoloration of the coating may occur when tannin extractives are dissolved into the coating solution by water, reach the surface and remain as dark, coffee-brown stains after the water evaporates. This reddish-brown bleeding is unsightly, but not damaging to the coating.

4) Paint Peeling:
Paint adhesion is loss and the loose paint starts coming off in single to multiple coats
Caused by improper surface prep., and not identifying the conditions that need pre-painting attention, Uncontrolled moisture conditions, painting over rusty nails, loose paint, chalking paint, and dirty surfaces.
5) Paint Blistering: dome shaped paint bubbles indicating loss of adhesion.
Causes- trapped moisture trying to escape through the paint, painting above 90%, using oil on wet/damp surfaces, humidity such as rain and a heavy dew before the paint dries and cures, painting a warm surface in direct sunlight or application over heavy chalking.
6) Paint Color Fading/Retention:
Oxidization occurs as soon as soon as the paint is put onto the substrate, When oxygen hits the substrate there is a build of oxygen molecules on the paint film surface which in turn gets underneath the paint and corrodes it from the inside out. There is no stopping this process because the substrate has been compromised. That is why it is so important to have full paint coverage and adhesion by pressing the paint into the substrate through the process of back rolling and back brushing.
7) Caulking Failure: Caulking failure occurs when oxidization is present, loss of the protective moisture seal due to the loss of initial adhesion and flexibility.
Probable causes- Filing too large of an opening, usually 1/4 of an Inch or bigger, wrong type of caulking for particular applications and exposure. Considerable movements or prolonged contact with settled water on caulking.
8) Alligatoring: Many wide patterned cracks in the paint film with the appearance of alligator scales.
Multiple of coats of oil based paints that have become brittle and start cracking. Insufficient drying times between coats. A hard coating over a soft primer. The top coat doesn’t bond correctly to anything with a glossy surface.
Paint that is aged through at least one coat will show you signs of cracking and flaking. Common causes are old oil based paint. This process of degradation : Loss of adhesion and flexibility which over time becomes hard and brittle. Poor surface preparation, Substrate cracking underneath paint film.
Excessive bubbling that doesn’t flow out and leaves craters or depressions in the paint film.
Incorrect nap roller length, painting too soon after shaking, playing in the paint i.e. rolling excessively, using old paint, painting over un-primed porous surfaces, painting in temperatures over 90 degrees.
