Product Data Sheet


Clear, 'Wet Look' Acrylic Sealer and Primer


Azcoseal is a premium clear acrylic in a solvent solution. Azcoseal is formulated to provide a versatile sealer capable of deep penetration into a wide range of substrate and cures to form a clean, tough (hard) and resilient coating in a satin (semi- gloss) finish.
Azcoseal is an effective and long lasting sealer against water penetration, wind driven rain and salt spray.
Azcoseal is also designed as a penetrative primer for subsequent water based and polyurethane waterproofing membranes and high build paints and coatings and is particularly useful in high density and low-porosity surfaces such as tilt-up slabs.
Applied to pavers, brick,sandstone and masonry surfaces, Azcoseal gives an appealing 'wet-look' finish.
CAUTION: Sealed surfaces may be slippery when wet.


The properties of AZCOSEAL make it ideal for:
• Sealing and weatherproofing porous substrates such as face brick against rain and salt spray.
• Providing a penetrative primer for water based and polyurethane waterproofing membranes, high build paint and architectural finishes on to porous substrates or over existing painted surfaces.
• Encapsulating and sealing friable substrates such as asbestos sheeting. 
• Providing an attractive 'wet-look' sealer over pavers, brick,sandstone and masonry surfaces.
• Reactivating existing acrylic coatings prior to recoating

Suitable Surfaces

Azcoseal is suitable for use on:
Concrete, cement, cement render, acrylic coatings and membranes, FC and CFC sheeting, blue board, block work, bricks, cement pavers, sandstone, concrete stencil and masonry surfaces.


The information contained in this product data sheet is typical but does not constitute a full specification as conditions and specific requirements may vary from project to project. The instructions should be considered as a minimum requirement but the applicator or contractor must use their skill, knowledge and experience to carry out additional works as may be necessary to meet the requirements of the project. Specification for specific projects should be sought from the Company in writing.


Test areas are highly recommended, particularly if coating pavers and terracotta tiles as solvents may dissolve entrapped salts which may discolour the coating and tile.
Cured coating may be slippery when wet.
If area becomes wet before product has cured, it may turn product to a milky colour.
If used as a primer in exposed applications, ensure that solvents have fully evaporated before top coating.  If not, there is a risk that the top coat may bubble.

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.
  • When used as a primer it enhances the water proofing properties of the overall system.
  • Low dirt pick - up.

Precautions in Use

Follow all safety precautions as per product label and data sheet. Azcoseal contains solvent and is therefore flammable while still wet. Ensure that all sources of ignition are kept well away. Ensure area is well ventilated. Adequate masks should be worn when spraying. Protect surrounds against over spray. 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.

Cured product may be slippery when wet.

Priming and Surface Preparation

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


All surfaces must be clean, dry, of sound construction, stable and free of any dust and mould, dirt, grease, oil, curing compounds or contaminates that might interfere with adhesion.
Remove efflorescence and wash area and allow to dry before application.  
When used as a primer best results are achieved if it is top coated as soon after the Azcoseal has fully cured.
Ensure solvents have fully evaporated.


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 4m² per liter per coat. Product should be worked well into the substrate.
• Clear weatherproof sealer: Two coats at 4m² per Lt per coat.
• As a primer: One coat at 4m² per Lt.
• Trafficable 'wet - look' finish: Three coats at 4m² per Lt per coat.

Allow each coat to dry before applying each additional coat. For best results apply subsequent coats within 24 hours of the previous coat.


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


General coverage rate: is 4m² per Lt per coat.


Azcoseal is a clear product and dries to a clear, semi-gloss finish.

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 and therefore drying and curing can only be given as a guide.


At 25ºC and 50% RH (per coat):
• Touch dry: 1 to 2 hours
• Dry: 2 to 6 hours
• Full cure: Within 24 hours.

Service Temperature: 10ºC to 50ºC
Application Temperature: 5ºC to 30ºC


Azcoseal should be stored in a cool, dry place and kept clear of sources of ignition as product is flammable.
Class 3 dangerous goods must be declared prior to transportation. 
Azcoseal is available in 4 and 15 Lt pails.

Clean Up

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

Tiling, Topping or Top Coating

If used as a clear sealer the product is not recommended to be tiled or topped as the product is usually left exposed.
However if used as a primer then the product can be over coated with suitable Duram membranes and coatings.

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.
Keep all sources of ignition away from product.
Use only in well ventilated areas.


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

Tests and Technical Data

Shelf Life: Up to 12 months in unopened containers and 6 months after resealing open pails. Performance and shelf life can vary when stored in extreme conditions.
