New Growth Wood Siding will not hold Paint...

On sound wood siding, however, these great heavy acrylic coatings are being used and the jobs are failing often.  At first glance, adhesion deficiencies seem to be the reason for the failures.  This is not the reason that many of the jobs fail in two to three years after application.  The very high quality nature of the coatings is the reason for their demise.

An envelope is created when a heavy acrylic is applied onto the exterior of a building.  This envelope that is applied to the exterior of buildings becomes a monolithic wrapping, sealing in any hope for moisture pressure to escape from the inside of the outside.  In the Northeast, winter residential interior pressures are intense and with the heated air comes moisture vapor.  Interior, moisture laden air can easily penetrate walls, insulation and wall sheathing, etc.  The moisture often finds its way through the siding and to the back-side of these new acrylic envelopes.  As the moisture condenses, water accumulates and the pressure of changing exterior environments causes a percolation effect that separates the acrylic envelope from the substrate (siding). 

With all of the reasons being given for these failures, the scenario described above holds more validity than any.  With many of the new products being advocated as the answer to paint problems, a second look should be taken as to how the products are applied.

We do have the answer with our factory finishing system which utilizes the finest acrylics technology can offer.  When we install our Fiber Cement pre-finished products, they are fully cured and installed so as to allow full ventilation, as well as true watershed.  (See Photo below for diagram - Also this page for explanation and comparison to other types of sidings)  It is the Fiber Cement substrate, very stable, pre-finished, and self ventilating which holds the world’s best coatings, while still allowing moisture to vacate during the winter months. 

Truly, with the high cost of re-painting old substrates with the promise of long lasting coatings, it is just too costly to have a failure in several years down the road.  When our acrylics are factory applied to Fiber Cement Siding, fully cured, and then installed by our professional installers, you have a warranted, stable system that will last for many decades.

We also finish our very stable, insect and rot resistant solid composite trim packages in the same acrylics so that your home looks like a custom carpenter did the job for many years to come.
