Dryvit RapidPatch is an exceptional patching material specially engineered to patch holes in an existing EIF system up to a maximum depth of 1 in (25 mm).

Application Procedure:
Job Conditions – Air and surface temperature for application of RapidPatch must be 40 °F (4 °C) or higher and must remain so until RapidPatch is cured. When ambient temperature is above 75 °F (24 °C), water used for mixing should be chilled to a temperature less than 75 °F(24 °C).

Temporary Protection – Shall be provided at all times until patching material, finish and permanent flashings, sealants, etc. are completed to protect the wall from weather and other damage.

Surface Preparation – Surface must not be below 40 °F (4 °C) or painted and must be clean, dry, structurally sound and free of efflorescence, grease, oil, form release agents and curing compounds.

Mixing – One pail of RapidPatch will produce approximately 1 gal (3.78 L) of RapidPatch mixture. RapidPatch may be mixed by mechanical or manual means. RapidPatch should be mixed to a thick consistency such that it does not sag on the wall.

Mechanical mixing: To a clean 1 gal (3.78 L) pail, add 0.8-1.0 qt (0.77-0.95 L) of clean potable water. Add the RapidPatch slowly while
constantly mixing with 2 in (50 mm) ribbon type mud mixer (such as Marshalltown® Part No. RM771) at 450-500 rpm. Thoroughly mix until uniformly wetted, adjusting consistency with a small amount of water or RapidPatch. Let set for 4-5 minutes. Retemper, adding a
small amount of water if necessary. Material must be free of lumps before using.

Manual mixing: Add the measured small quantities of RapidPatch to the proper amount of clean portable water in a clean container and mix with a margin trowel. Mix for 3-5 minutes and let it set for 4-5 minutes. Re-mix to break the set for 1 minute and add a small amount of water if necessary. The pot life is 20-30 minutes depending on ambient temperature.
