EIFS Caulking and Sealants
When it comes to EIFS caulking and sealants it is something you really have to take seriously
According to Dryvit, Tremco Commercial Sealants and Waterproofing’s Spectrem® 1, Spectrem® 3, and Spectrem® 4-TS are all approved sealants.
Here are the individual product descriptions from Tremco Commercial Sealants and Waterproofing
Spectrem® 1 is an ultra low modulus, high performance, one-part, moisture curing silicone joint sealant.
Spectrem® 2 is a medium modulus, one part, high performance, neutral cure silicone sealant ideal for a variety of caulking and glazing applications.
Spectrem® 4-TS is a multi-component, neutral-curing, low-modulus silicone sealant specially formulated for use in dynamically moving building joints with + / – 50% movement.
Using the proper sealant on an EIFS project is very important. If you use the the wrong type of sealant it may fail prematurely or even worst it may actually eat away at the foam. If you use Tremco sealants on your Dryvit project you can get a two year extension on your warranty. That of course, is only on a Dryvit warranty, it does not apply to all EIFS manufacturers.
