Chapter 3 Summery Questions Flashcards
Describe the difference between primer foundations
Primers may be sealers or underbodies
Sealers block stains that might rise through the paint; underbodies conceal minor imperfections in the surface.
Alkyd primers are used where water would damage the surface, like iron, which would rust
Latex or acrylic primers are water-based
Latex primers ar emoe flexibel acrylic primers are harder
How are primers different from paints?
Primers prepare the surface for paint and paint protects the surface
Describe the different paint formulas, highlighting their differences
Epoxy paints are two-part
systems that are very durable against abrasion and staining.
Solvent-based alkyd formulas are
for surfaces that cannot be painted with water; they tend to dry more slowly to a smoother finish.
Plant based oils are used to produce modified alkyds that are emulsified water and oil.
Latex and
acrylic paint are water-based paints.
Rank sheen level in order from lowest to highest using standard industry terminology
- Gloss
- Semi-gloss
- Satin
- Eggshell
- Flat
How would you explain to your client why one contractor’s bid is higher than another’s?
I would compare the description of the work and the presswork and steps
I would look at the product to be provided and see if the quality of material was comparable
How would you inspect for when the walls are primed?
Even coverage Sags Dents Chunks of material in paint The quality of sanding the surface and making it smooth
What would be on your checklist to inspect for when walls are painted?
Even coverage Sags Dents Chunks of material in paint Consistency of surface sheen and complete coverage with no thin spots
What is skim coating? What are the benefits of it?
Applying a layer of “hot mud” to the entire wall
surface in a manner similar to spackling.
It provides a hard surface and better acoustical
separation because it is just slightly denser.
How are faux finishes created?
They are made by applying multiple layers of translucent glaze
What sustainability issues pertain to paint and painting?
Durability and a proper spec are the
starting points of a sustainable installation
Specify water-based product with low VOCs.
What are some alternative materials if you want lower toxicity and more sustainability than is typical?
Earth plasters, milk paint, and other traditional formulations used before the advent of
modern petroleum-based chemistry tend to be low toxicity.
What organizations issue guidelines pertaining to air quality with regards to paints and coatings?
AIM SCAQMD CARB OTC Greenseal Greengaurd LADCO
What are the different decorative faces used for wall coverings, and what are the differences in their performance?
Paper is easily printed but the face is not durable unless it is coated paper. Paper
may have a vinyl applied or a vinyl film adhered (which is the more durable of the two).
Fabric
can be laminated to a backing and applied to walls but care must be taken to protect the surface
from adhesive when the covering is applied.
Vinyl is a durable surface that is often specified to
protect the walls beneath it.
Wood and cork veneer are also popular faces for wallcovering. They may need to be protected with a clear coat if one has not already been applied.
What backings are used, and what circumstances indicate the use of which wall covering?
Backings must be
paired with the face of the wallcovering.
A heavy vinyl face indicates a heavy drill backing.
If the
backing must be somewhat pliable to match the face, then an acrylic backing makes sense
Paper backings vary in thickness and surface quality
Non-woven backings are also somewhat
flexible.
What is the distinction between custom wallcovering and custom colorways?
Custom wallcovering
is a unique pattern and color whereas custom colorways means that the patterns are available
in different (stock) colors.
