Latex paints are widely used in residential and commercial indoor environme
nts. The surface areas covered by the paints in these environments are rela
tively large. Thus, latex paints have the potential for having a major impa
ct on indoor air quality (IAQ). A study was undertaken to develop methods f
or evaluating the impact of latex paint emission on IAQ. Small chamber expe
riments using stainless steel and Fainted and unpainted gypsum board substr
ates were conducted to determine the emission characteristics of latex pain
t. The emissions from the stainless steel were relatively short lived (3 to
4 days), whereas the emissions from gypsum board lasted for over 200 days.
Because gypsum board is a common substrate for latex paint, all emission m
odels were developed for the gypsum board substrates. The data from the sma
ll chamber tests led to the development of two empirical and two mass-trans
fer-based source emission models. Approximately 100 to 200 days of data wer
e required to estimate the parameters required for the empirical models. On
ly 8 days of data were required to estimate the parameters for the mass-tra
nsfer-based models. The final models use paint formulation and mass transfe
r correlations to predict the emissions of the major individual volatile or
ganic compounds emitted by latex paint.
