Role of primer in house painting

All too often house painting companies skip this very crucial step when painting exteriors.  Unsuspecting home-owners can not tell the difference between a well prepared and primed surface, and a paint job that produces substrate protection for only a short period of time.  It is important that you hire only reliable and established painters who have proven themselves over time.  Drive by and see some of their model homes, contact references, and learn how long the painting company has been around.

House painting and wood rot

Raw wood is constantly trying to return to nature (rot).  Wood surfaces breath and have a natural humidity of ten to fifteen percent.  This humidly level fluctuates based on air humidity.  When exposed to high humidity, dead wood will capture some water from the air.  Living plants have microscopic pockets of water, but in dead wood, these pockets are consumed by fungai, and the walls between the pockets open up. This allows more moisture to be absorbed in the wood, providing more humid wood, which is more favorable to rapid growth of fungi, thus accelerating the decay of the wood.

 

Role of Primer in Exterior House Painting

elegant painting primer sammamishPriming is mandatory for exterior surfaces in our damp climate.  Primer acts as sealant.  It covers water stains, oil stains, and any other material that be be present on the substrate.  Wihtout primer, your wood siding is exposed to the elements. Primer is an under-coat applied before painting.  Priming improves adhesion, increases durability, and is an excellent protector for exterior substrate.  As paint dries, it undergoes chemical reactions.  Water evaporates from paint as it cures.  Primer controls the curing pace of finish paint and allows it to cure slowly while the chemical reaction is taking place.

Applying Exterior Primer

Primer should never be sprayed on.  Having a thin, sprayed layer of primer sitting on the surface offers little to no protection.  Brush and roll method is recommended to ensure proper penetration, even spread, and better adhesion.

Exterior Painting Preparation

Painting Preparation is key to a durable, professional paint-job that can withstand our damp Northwest climate.  Elegant Painting uses the following professional Preparation techniques to prepare exterior surfaces for painting. This process removes any loose or chipping paint and mildew, leaving the substrate ready for primer & paint.

 

 

Steps:

Washing is the first step in any painting job.  After moving items, such as patio furniture, planters, garbage cans, etc. a safe distance away, we wash they house by first soaking each wall, then we apply a mixture of TSP and bio degradable house bleach to any visible mildew and water-stains.  The solution is then allowed sixty seconds to activate and washed using Honda power washers.  The tip of the wand is kept a safe distance away from siding to prevent damage.  Windows and doors are rinsed from an even further distance to prevent water entering the house.  After the wash, we rinse all exterior surfaces to remove any debris before they dry.

Sanding & Scraping

After allowing sufficient drying time, our painters remove any peeling or chipping paint.  We start by using Makita disk sanders to remove not only paint that is currently peeling, but also anything that we feel might peel anytime in the future.  The Makita disk sanders remove loose paint as well as any early stages of dry-rot that might be developing underneath, leaving the substrate ready for primer.

Caulking

Caulking is done after the primer has dried.  Much like paint, Caulking materials adhere best to primer.  We caulk all gaps, cracks, nail-holes, and joints.
