Dryvit ShieldIt Base Coats are acrylic polymer-modified products, which are mixed in a proprietary ratio to produce the two composite base coats for: Dryvit ShieldIt warranty program, warding off woodpeckers; and improving point impact resistance, such as on pedestrian wall areas, and decorative EIFS trim.

The components are as follows:
ShieldIt 1st Coat (Dark Grey): Mix with Type I or Type II (Type 10 or Type 20) Portland Cement. This coat could be referred to as the
“scratch” or “screed” coat.
ShieldIt 2nd Coat (Light Grey): Mix with Type I or Type II (Type 10 or Type 20) Portland Cement. This coat could be referred to as the
“level” or final “skim” coat. Each product provides a medium build, base coat over top of existing EIFS lamina, or reinforced base
The ShieldIt Base Coats are used over existing EIFS and new EIFS base coats to provide a layer of protection against damage from woodpeckers and similar pests. The combination of the two ShieldIt Base Coat layers changes the surface characteristics to deter fowl from pecking their way through an EIFS lamina.
Note: ShieldIt is not recommended to have reinforcing mesh embedded into it – the coarse texture of the product is intended to be applied onto existing EIFS lamina, or newly applied Dryvit reinforced base coat.
Working Time: After mixing. The working time of the ShieldIt Base Coats is approximately 1 hour depending on ambient conditions.
Drying Time: The drying time of the ShieldIt Base Coats is dependent upon the air temperature and relative humidity. Under average drying conditions [70 °F (21 °C), 55% R.H.], the mixture will dry in 24 hours. Protect work from rain for at least 24 hours. Being cementitious products, the ShieldIt Base Coats will develop full strength in 28 days.
Job Conditions: Air and surface temperatures for the application of the ShieldIt Base Coats must be between 40 °F (4 °C) and 100 °F (38°C) and must remain so for a minimum of 24 hours.
Temporary Protection: Shall be provided at all times until the adhesive, base coat, finish and installation of permanent flashings, sealants, etc. are complete to protect the wall from inclement weather and other sources of damage.
Acceptable Substrates: Existing EIFS lamina (reinforced base coat and finish) that is clean, dry, and in good serviceable condition – including decorative EIFS trim, profiles and moldings; or upon consultant with Dryvit, on new Dryvit EIFS reinforced base coat, prior to the finish coat application.
