Air Leakage and Moisture Intrusion in Single-Wythe Masonry Walls

Buildings, Commercial, Moisture / By

While water is life-sustaining to humans, it is detrimental to buildings; especially ones made from single-wythe concrete masonry walls.  It causes paint to fail, cracks to form in mortar joints, and blocks to spall.  These deficiencies are unsightly and reflect poorly on brand, and over time, moisture intrusion can result in the complete deterioration and …

Use of Fire Resistive Coatings in Building Construction

2 Comments / Buildings, Commercial, Fireproofing / By

Fire resistive coatings generally refers to a broad group of materials known as sprayed fire resistive materials (SFRM).  These coatings provide protection to structural steel in buildings and other structures by serving as an insulative layer in the event of a fire.  The coatings are rated by how long they provide such protection, typically from …

Localized Assessment of Air Leakage in Building Air Barriers

Buildings, Commercial, Concrete Walls, Inspection, Instruments / By

ANSI/ASHRAE/IES Energy Standard 90.1-2010 and the 2012 International Energy Conservation Code require that building envelopes be designed to limit uncontrolled air leakage into and out of buildings. Air leakage in buildings is controlled at the time of construction by installing air barrier systems.  ASTM E1186-17, “Standard Practices for Air Leakage Site Detection in Building Envelopes …

scrubability

What is Scrub Resistance of a Paint and Why is it Important?

Commercial, Lab Testing / By

In the paint industry, the property of scrub resistance is measured as the ability to resist wearing or degradation of a dried paint film. The wear or degredation is assessed either visually or by weight loss, when using a scrubability instrument or an abrasion tester.  According to the ASTM test methods governing scrub resistance testing, …

Wind-Driven Rain Resistance Testing of Exterior Coating Systems

2 Comments / Buildings, Coating Assessment, Commercial, Concrete Walls, Lab Testing / By

Controlling moisture intrusion from blowing rain is a fundamental part of designing a functional and durable building. Driving rain is typically the largest source of bulk moisture for above-grade building assemblies.1 Inadequate wind-driven rain resistance can lead to moisture intrusion in building assemblies that are intended to stay dry, causing problems for building owners and …

Measuring Gloss Retention in the Coatings Industry

Buildings, Commercial, Lab Testing / By

Background The gloss level of a coating is selected primarily for aesthetics. Choices can range from flat to egg shell, satin, semi-gloss and gloss. Industrial protective coatings are not always available in each of these five levels. The gloss of a protective coating changes over time; these changes may be caused by aging of the …

Determining the Presence of Asbestos in Commercial Buildings

Commercial, Health & Safety / By

When planning and designing building renovations and additions, facility upgrades and demolitions, consideration needs to be given to determining whether asbestos-containing materials (ACM) are present in the areas of proposed work.  Lack of pre-planning for the assessment of the spaces for ACM can lead to significant scheduling delays as well as cost overruns or change …

The Significance of the Permeability of Paints

Buildings, Commercial, Concrete Walls, Lab Testing / By

Permeability of Applied Paints & Coatings… Do I want a permeable coating or not? The answer to the question posed is based on the substrate and the service environment. All paint and coatings are permeable to water, just to different degrees. A high resistance to permeability is likely desirable for lining applied to the interior …
