-Water-based:
latex = more flexible than acrylic
acrylic = a little harder than latex
both = cause grain rising of bare woodwork
How are primers different from paints? -CORRECT ANSWER ->>-Primers: prepares surface for paint
(creating good bond between the substrate and paint)
-Paint: protect surface, decorative element
Describe the difference paint formulas, highlighting their difference. -CORRECT ANSWER ->>-Epoxy

reused to produce modified alkyds that are emulsified water & oil
, -Latex and acrylic paint:

-Sags
-Dents & chunks
-Quality of sanding = surface is smooth
Checklist to inspect for when walls are painted? -CORRECT ANSWER ->>-Roller marks
-Lap Marks
