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.
Until recently, you had to wait one to two months for the stucco to cure properly. However, new-generation masonry primers speed up the process considerably. For instance, Loxon Exterior Masonry Primer from Sherwin-Williams can be applied as soon as the stucco is hard, dry and at a pH level of less than 13. After the primer dries, you can follow with latex house paint immediately.
