Temperature of Working Area
- Maintain a temperature of 60°- 85°F on air, substrate, Liquid, and Hardener components during mixing, application, and cure. The material components should be maintained at 65°F to 85°F for 48 hours prior to beginning work.
- At temperatures below 65°F, the application becomes more difficult and curing is retarded. Above 80°F, the material working time decreases.
- Application in direct sunlight and rising surface temperatures may result in blistering of materials due to expansion of entrapped air or moisture in the substrate. Concrete that has been in direct sunlight must be shaded 24 hours prior to application and remain shaded until after the initial set. When the surface temperatures are rising, it may be necessary to postpone the application or apply during cooler hours.
Surface Preparation
- New Concrete - All structures must have the necessary strength to withstand imposed loads during normal use and operation. Surfaces should be floated free of ridges or depressions and all voids filled with Sauereisen Underlayment No. F-120 or Filler Compound No. 209. The choice of underlayment will depend on the severity of the voids to be filled. Surfaces should be sloped 1/8 to 1/4 inch per foot for drainage. If No. 209 is the material of choice, it must be applied AFTER PenePrime No. 500.
- Substrates must be free of oil, grease, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. Abrasive blast, high-pressure water blast, or acid etch concrete to remove laitance and to obtain a uniform surface texture exposing fine aggregate resembling coarse sandpaper.
- Old Concrete - Concrete must be dry, firm and must have the necessary strength to withstand imposed loads during normal use and operation. Mechanical methods should be utilized to remove laitance, old paints, protective coatings, and attacked or deteriorated concrete. Surfaces must be free of oil, grease, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. Abrasive blast, high-pressure water blast, or acid etch concrete to obtain a uniform, sound substrate. All structural cracks should be repaired and all slopes should be reestablished with Sauereisen Underlayment No. F-120.
- Brick - Surfaces must be free of oil, grease, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. Abrasive blast or high pressure water blast all foreign particles and attacked or unsound mortar from the joints. Loose brickwork should be regrouted with appropriate Sauereisen mortar to ensure structural integrity. Mortar joints should be repointed to be flush with the face of the masonry units.
- If chemical cleaning is utilized to remove contaminants, substrate must be neutralized. If abrasive or high-pressure water blasting is used as the method of surface preparation, all sand and/or debris must be removed by thoroughly vacuuming the area with an industrial vacuum cleaner.
- If surfaces do not have desired conditions, repeat surface preparation procedures.
- Application
Mixing
- Primers are packaged in premeasured containers consisting of Hardener Part A, and Liquid Part B which must be mixed together before use. Remix the Part A and Part B before combining.
- Completely empty contents of Hardener Part A into Liquid Part B container. Using a slow speed 1/2 inch drill motor with a "Jiffy" type blade, mix thoroughly for three minutes until blended to uniform color. Primer is ready for use immediately after mixing.
