Applications & Uses
- Markets
- Application Method
- Substrate Requirements
- Substrate temperature must be a minimum of 55°F before, during and 72 hours after installation.
- It must have an effective vapor barrier directly under the substrate.
- It must be used only on properly prepared surfaces.
- The surface must be free of dirt, waxes, curing agents and other foreign materials.
- It does not function as a crack reflective membrane.
- Considerations
- Do not use solvent-based acrylic as a primer.
- Use over properly prepared concrete surfaces.
- Applications heavier than 200ft²/gal may result in solvent entrapment and possible blistering.
- Effective moisture vapor barrier needed directly under concrete slab.
- Surface Preparation
- Surface Preparation is the most critical portion of any successful resinous flooring system application.
- All substrates must be properly prepared as outlined in Düraamen’s Technical Bulletin # 1.
- Work must be performed by trained or experienced contractors or maintenance personnel.
- Installation
- Apply Perdure AU52 over properly prepared surfaces.
- Surfaces must be free from oils, grease, water or other foreign matter.
- The surface should be dry and above 50°F and rising.
- Relative humidity should not exceed 85%.
- Perdure AU52 is moisture sensitive during application and initial cure.
- Do not apply if the surface temperature is within 5°F of Dew Point.
- Not recommended on floors susceptible to hydrostatic pressure.
- The best methods of application are using lambswool applicators or mohair rollers.
- Perdure AU52 can be brushed by using pure Chinese soft bristle brushes.
- For rolling, use a shed-resistant phenolic core mohair cover.
- Roll in the same direction, always keeping a wet edge.
- Do not over roll product.
- For safety and proper curing, proper ventilation is necessary throughout application and cure.
- When using pigmented intermediate coats, be sure the batch numbers are all the same to provide a uniform base color.
- Perdure AU52 can be sprayed with an airless or conventional unit.
- Clean Up
- Clean skin with soap and water.
- Tools and equipment should be cleaned with Xylene or Lacquer Thinner.
- Coverage
- Perdure AU52 yields 300ft² per gallon at 3 mils dry film thickness.
- Thicker application may result in bubbles in the cured film.
