by evaporation
chemically
by adding heat
by smoothing with solvent-soaked cloths
The property that best indicates the tools required for application is:

oil-based sealants and fillers
solvent-based sealants and fillers
chemically curing sealants and fillers
resin-based sealants and fillers that do not contain solvents
Which of the following is not a purpose of sealants and fillers?

If finished wood is not deglossed when the sealant is applied to a joint;
adhesion will be better
adhesion will be the same
adhesion will be poor
cohesion will change
If the primer is still wet when sealant is applied to a joint:
adhesion will be better
adhesion will be the same
adhesion will be worse
cohesion will change
If sealant rips away for the substrate without elongating during a hand pull test, the:
substrate failed and requires replacing
sealant must not be very flexible
sealant adhesion is perfect
sealant adhesion to the substrate is poor
