Lastic

Performance Characteristics

• Flexible Retains elasticity at low temperatures.
• Waterproof Two 15 mils. wet coats provide waterproof membrane.
• Anti-carbonation Mitigates carbonation of concrete.
• Breathability Water vapor permeable.
• Alkaline stable Formulated for highly alkaline substrates.
• Durable UV stable. Mildew resistant.
• Colorfast Premium quality exterior grade pigments, minimize fading.
• Textures Available in sanded and smooth finishes.
• Extensive color spectrum 38 standard colors and custom matching.

Surface Preparation

• Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper adhesion.
• Prepare surface to a sandpaper-like texture (CSP 3) by mechanical abrasion or medium water blasting. Refer to ICRI Surface Preparation Guide 03732 for information about Concrete Surface Profile (CSP).
• Surface must be dry and frost free.
• Small voids, air pockets, static cracks up to 1/16 inch and irregularities should be filled with Plastermix.
• Repair larger voids and damaged areas with Conpro Set.
• For cracks greater than 1/16 inch, rout and caulk with a urethane sealant. Refer to SWRI Sealants – The Professionals’ Guide.
• Apply Plastermix to concrete where a monolithic, void free texture is desired.
• Apply Plastermix on reinforced concrete to increase carbonation resistance.

Priming

• Priming is not necessary under normal circumstances.

Mixing

• Stir or mechanically mix using a low speed drill (400 – 600) until homogenous.
• Mix pails from different batches when an entire surface is visible.

Application

• Apply a test sample to determine adhesion. Test using ASTM D3359 cross-hatch adhesion procedure.
• Substrate temperature must be above 45°F.
• Ambient temperature must be above 45°F for the entire curing period.
• Roll, spray or brush apply a uniform 15 mils. wet – dries to 7 mils.
• For roller applications use a 1 – 1-1/4 inch synthetic nap roller depending on texture of substrate.
• For spray applications use a Graco 3500, President or Bulldog or equivalent with a 0.041 – 0.047 tip. Refer to Conproco Black Book.
• Spray application must be back rolled for a pin-hole free surface.
• Work to pre-determined break points in the structure.
• Maintain a wet edge.
• Apply a second coat when the first is dry-to-touch.

Curing

• Protect from moisture for 24 hours and wind driven rain for 72 hours.

Clean Up

• Clean tools and equipment with water. Clean adjacent areas with water before material dries.

Coverage/Yield

• 100 ft²/gal. @ 15 mils. wet for smooth surfaces.
• 50 – 75 ft²/gal. @ 15 mils. wet for split block or rough surfaces.

Product Handling

• Packaging 5 gallon containers
• Shelf Life 18 months in unopened containers.
• Storage Protect from freezing. Transport and store in cool, clean, dry conditions in unopened containers. High temperature will reduce shelf life.

Limitations

• Do not apply if precipitation is forecast within 24 hours of application.
• Do not apply in strong winds.
• Do not apply to horizontal or overhead surfaces.
• Do not apply to frozen surfaces.
• Do not apply if temperature of substrate is below 45°F.
• Do not apply if ambient temperature is below 45°F.
• Do not apply in areas susceptible to ponding water.

Health and Safety

• Product is alkaline.
• Do not ingest.
• Avoid contact with skin and eyes.
• Avoid breathing vapors.
• Refer to Safety Data Sheet (SDS) for additional information.

First Aid

• In case of skin contact, wash thoroughly with soap and water.
• For eye contact, flush immediately with a high volume of water for at least 15 minutes and contact a medical professional.
• For respiratory problems, remove person to fresh air.
• If respiratory difficulty persists, contact a medical professional.

Disposal

• Dispose of material in accordance with local, state and federal regulations.
