Series 208

Epoxoprime MVT

Generic Type

Modified Polyamine Epoxy

Common Usage

Epoxoprime MVT is a unique, moisture-tolerant, two component, low viscosity, high solids epoxy primer designed to reduce moisture vapor emissions and provide alkalinity control for concrete with elevated moisture vapor transmission levels that exceed the acceptable limits of non-breathing resilient and polymer floor topping finishes. Epoxoprime MVT can be applied to properly prepared, 10 day old concrete and withstands moisture vapor transmission up to 15 lbs (per ASTM F 1869) and relative humidity up to 95% (per ASTM F 2170). Epoxoprime MVT has a low perm rating (0.05 perm) and is alkaline insensitive to pH levels of 14.

Special Qualifications

Series 208 was tested in accordance with, and passed, the California Department of Public Health CDPH/EHLB/Standard
Method Version 1.1, 2010 emissions testing and meets qualifications of LEED v4, Collaborative for High Performance
Schools, and Living Building Challenge.

Number of Components

Two: Part A and Part B (2 Parts A to 1 Part B by volume)

Recommended DFT

16.0 to 20.0 mils (406 to 508 microns) per coat. Note: The potential for outgassing increases with higher film thickness. Care should be taken during application to reduce these occurrences. Reference the application section of this product datasheet for important information on environmental requirements.


Series 201, 205, 206, 206SC, 210, 222, 223, 224, 233, 237, 237SC, 238, 239, 239SC, 247, 248, 280, 280FC, 281, 282, 290, 291, 294, 295, 296, 297. Note: Refer to the applicable topcoat data sheet for color availability and additional information. Note: If Series 247 (tinted), 248 (tinted), 290, 291 or 297 is selected for the finish coat, Series 208 must be tinted or a tinted intermediate coat must be utilized.

Curing Time

Temperature To Topcoat Max Recoat
75°F (24°C) 6-8 hours 24 hours

Note: If more than 24 hours have elapsed between coats, the coated surface must be mechanically abraded before
topcoating. Note: If Series 208 is used as the primer for an epoxy mortar system, the 208 primer must be reprimed with Series 201 or 237 prior to placing the mortar. The mortar application should take place while the Series 201 or 237 is still tacky, typically up to four hours, otherwise, aggregate should be lightly broadcast into the 201 or 237 primer while wet so to provide anchor points for the trowel application. Do not broadcast aggregate into the Series 208 Epoxoprime MVT.
