Specification

The information contained in this data sheet is general in nature and refers only to the usual use of the product and it should not be construed to be a complete specification. Site conditions vary which may require the use of the products and related products to vary. For specific projects a written specification should be sought from the Company.

Benefits and Advantages:    

Quick drying - usually within 1 hour.

Dries tough and hard.

Provides a waterproof and weatherproof barrier against water ingress.

Minimises surfaces fragmentation as it has excellent binding properties.

UV resistant, suitable for exposed areas.

Dries clear with an attractive satin finish.

It can be re-coated.

Low dirt pick-up.

Precautions in Use

When applying AZCOSEAL it is strongly recommended that all safety precautions are followed as per product label and data sheet.
As the product contains solvent ensure that all sources of ignition are kept away. Ensure area is well ventilated. Adequate masks should be worn when spraying. Protect surrounds against overspray. Observe all precautions on the Material Safety Data Sheet.
In exposed areas, do not apply if rain is imminent and protect coating from rain and inclement weather until fully cured.

Priming and Preparation

Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of loose, flaking, friable material, dust and substances that may diminish adhesion.

Application

AZCOSEAL can be applied by brush, roller or spray at the following minimum application rates(increase rates for highly porous surfaces):
As an encapsulating binder: Two coats at 4 sq m per litre per coat. Product should be worked well into the substrate.
Clear weatherproof sealer: Two coats at 4 sq m per litre per coat.
As a primer: One coat at 4 sq m per litre.
Trafficable 'wet-look' finish: Three coats at 4 sq m per litre per coat.
Substrates should be clean, dry and sound.
Allow each coat to dry before applying each additional coat.
For best results apply subsequent coats within 24 hours of the previous coat.

Coverage

The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique.

General coverage rate for AZCOSEAL is 4 sq m per litre per coat but it is dependent on the porosity of the surface on which the product is being applied.

Colours

AZCOSEAL is a clear product.

Drying and Curing

Drying and curing of the product is affected by type, dryness and porosity of the surface, temperature, humidity, ventilation, climate conditions and application technique. Therefore drying and curing can only be given as a guide.

Clean Up

All tools and equipment should be cleaned in solvent as soon after completion as practical.

Tiling, Topping or Top Coating

Not recommended as product is usually left exposed

Safety & Precautions

Sealed surfaces may be slippery when wet.
The use of solvent-resistant gloves, mask and eye protection is recommended.
Observe the safety precautions on the Product data sheet and Material safety Data Sheet.  

For full safety data refer to the product's Material Safety Data Sheet. Observe precautions as per label

Health Warning Information

Health Effects

Swallowed: Ingestion causes burning sensation, vomiting and salivation. Minute amounts aspirated into lungs can produce bronchio-pneumonia or pulmonary oedema.

Moderately toxic.

Eyes: Irritation and burning. Long term exposure can cause corneal burns.

Skin: Irritation and burning sensation. Can cause dermatitis.

Inhaled: Irritation with asthma-like symptoms. In high concentrations the product can cause nausea, vomiting and headaches. Vapours are anaesthetic and central nervous system depressants.

Chronic: Repeated exposure to eyes may cause reversible damage, bone marrow damage, low blood count, liver & kidney damage.

Swallowed: Do not induce vomiting. Give milk or water to drink and seek medical advice immediately.

Eyes: Flush eyes with copious amounts of clean water, lifting eyelid to ensure any product trapped will flush out. Seek medical attention.

Skin: Wipe product off skin and wash skin with soap and water. Apply moisturising cream.

Inhalation: Remove person to fresh air. Urgently seek medical advice. If not breathing, apply artificial respiration.

Personal Protection: The use of solvent-resistant gloves, coveralls and goggles (against splashes) are recommended.

Keep flames, sparks and any other sources of ignition away from uncured product. Product is flammable.

Advice to Doctor

Treat Symptomatically.

Follow normal good industrial hygiene and chemical precautions, particularly in respect of flammability. Use in well ventilated areas and provide flame proof artificial ventilation if required to maintain concentrations below xylene exposure standard of 350g/m2 (TWA) 655 mg/m2 (STEL) or 100ppm.

Keep sparks and ignition sources away from the product during application, as the product is flammable.

Ventilation

Good ventilation is recommended.

The use of solvent-resistant gloves, coveralls and goggles (against splashes) are recommended. Keep flames, sparks and sources of ignition away from uncured product.

Vapours may collect in low-lying areas. Ensure adequate ventilation.

Safe Handling Information

Store in a cool dry place, away from direct sunlight and ignition sources. Class 3 dangerous goods must be declared prior to delivery.

Suitable containers: Plain metal pails as recommended by the manufacturer.

Check containers are labelled and not damaged.

Spills: Remove sources of ignition. Prevent spills from entering drains and waterways. Absorb with non- combustible absorbing material.

Discard to suitable landfill in accordance with local council regulations or controlled combustion.

Fire/Explosion Hazard
