- Composition
Neyra Asphalt Emulsion is an environmentally friendly, concentrated, high solids, mineral reinforced asphalt emulsion fortified with a high molecular weight polymer. The binder base is emulsified in our high temperature, high shear, state of the art manufacturing process. The hot blending process of the high molecular weight polymer and asphalt base resin along with other quality raw materials creates a homogeneous coating formulated to be job mixed with high sand loads, providing an exceptionally tough, long lasting, skid resistant surface.
Features & Benefits

- Ready-to-Use Product Features
- Features
- Environmentally Friendly: Contains less than 0.1% Polycyclic Aromatic Hydrocarbon (PAH) content. It is also a low VOC, nonflammable coating that contains no coal tar or emits obnoxious odors
- Fast Dry & Curing: Higher solids, polymer modified asphalt emulsion allows for a faster cure, opening to traffic faster
- Protects & Beautifies: Neyra AE forms a tight seal that is impenetrable to the destructive effects of sun, water and chemicals giving your pavement a deep black long-lasting color
- Tough & Durable: Neyra AE is a polymer modified, mineral reinforced asphalt emulsion blended with emulsifiers and surfactants for superior durability, adhesion and flexibility
Applications & Uses

- Basic Uses
Neyra AE extends the service life and reduces maintenance costs of asphalt pavements, protecting them from the destructive effects of water, sunlight and oxidation. When mixed and applied according to manufacturer’s recommendations, Neyra AE provides a new looking, long lasting surface that is easy to clean.
- Preparatory Work
The asphalt surface must be structurally sound, surface cured and free from all loose or foreign matter prior to the application of Neyra AE.
- Methods
Neyra AE can be applied by spray, squeegee, brush or mechanical equipment designed for this purpose. Due to the heavy body of the Neyra AE slurry mix, application by means of specialized equipment is recommended. This equipment can be of two types, high volume positive displacement airless spray or mechanical squeegee. Both types must be capable of keeping material thoroughly mixed and homogenous throughout the application process. All equipment used must be capable of supplying a sufficient quantity of material for uniform application over the entire width of the application mechanism to provide a uniformly coated surface.
- Mix Design
- Neyra AE is a highly concentrated material intended to be mixed with water and mineral aggregate to form a ready to use pavement sealer
- Do not over dilute
- Use only Neyra additives specifically designed for Neyra AE
- Do not use other additives that are not chemically compatible with Neyra AE and will degrade the emulsion
- All sand used should be clean, dry, pure silica sand, free of contaminants
- Medium fine sand with an A.F.S. rating of 50 to 70 gives best results
- There should be no more than 2% retained on 30 mesh or coarser, no more than 10% retained on 140 mesh and no more than 0.3% retained on 200 mesh

For use over sound asphalt pavement, the following application procedures are recommended for best results:
Gal/SY Gal/SF Concentrate (Per Coat) 0.1 0.11 Mix (Per Coat) 0.13 - 0.15 0.014 - 0.016 One gallon of concentrate will cover 90 square feet per coat. Multiply square yards of surface x 0.1 to determine gallons of concentrate per coat. Coverage rates can vary with the application method and the age, texture and porosity of the pavement to be sealed. For low to moderate traffic areas, we recommend applying two full sand slurry coats. For high traffic areas, a third coat is advised. For highly oxidized surfaces, a primer, Polyprime (Product Data Sheet 155) is recommended. Each coat must be dry before additional applications. On a typical parking lot, a combination of application systems could be used. For example, two coats for the parking stalls and a third for the drive lanes where most of the wear occurs. Application must be made when ambient temperatures and pavement temperatures are above 50° F. Good drying conditions above 50° F are required during the subsequent 8 hours and no temperatures below 50° F should be anticipated for 48 hours. Night time application is not recommended. It is recommended that the area over which the application is made be opened to use only after trial shows it to be dried and sufficiently dry to accept regular traffic. Lower temperatures, high humidity, clouds or shade, and lack of air movement slow drying time. Do not apply when rain is imminent.
Caution: Application of this product in marginal weather conditions or over dilution will result in premature wear.
- Maintenance
Occasional flushing with water will help to retain an attractive appearance.
- Caution
Application of this product in marginal weather conditions or improper mix designs can result in premature wear or product failure.

Safety & Health
- Precautions
Do not apply Neyra AE over chip seals, or sealers which contain gilsonite. Neyra AE is not recommended for use on portland cement concrete. Keep out of reach of children. Container should be closed when not in use. Contains petroleum distillates. Avoid breathing vapor or prolonged contact with skin or eyes. Flush immediately with water. New asphalt should be allowed to cure for a minimum of 30 days prior to application and must not exhibit ribboning, crawling, nor show oil rings when 1 gal. of clean water is poured onto the surface. Protect wet Neyra AE at all times from freezing and rain.
