Viruses are classified by the type of nucleic acid they contain, and the shape of their protein capsule. Examples of several viruses are shown in Figures 1-3. Figure 1. Structure of a variety of viruses. Image from http://www.gene.com/AE/AB/GG/examples_of_viruses.html.
Stucco is a durable and beautiful building material, but homeowners should accept that it just isnât waterproof. If youâre concerned about damage to your home, look from these signs that your stucco is, indeed, due for a waterproofing job: Paint coating stucco is chipping, peeling, fainting, or cracking.
Ideally, you are also able to install some rigid foam board underneath the Stucco to create a thermal break (the wood framing has very poor insulation value and is about 20% of your wall surface in an older home). The foam board should be paired with a weep screed and other best practice water managment systems.
