Extend the set time of conventional, veneer and lime finish
plasters and setting-type joint compounds.
Easy to use formulations meet a variety of setting times; allow time for
proper plaster application and finishing.
Gypsum Plaster Retarders extend the set time of conventional plasters,
veneer plasters, lime finish plasters and setting-type joint compounds.
By slowing the chemical crystal formation that causes gypsum plaster to
set or harden, Gypsum Plaster Retarders allow more time to complete each
job. Gypsum Plaster Retarders easily disperse into water prior to adding
plaster and are available in the following formulations:
Standard Strength Retarderis recommended for slight
to moderate (30 to 45 minutes) lengthening of set times for veneer
and conventional plasters and setting-type joint compounds
High Strength Retarderextends the set time by one
to three hours and is especially suitable for machine-applied
conventional gypsum plasters
