Preparation of Specifications

A robust specification reduces exposure by the owner and encourages attention to detail. It minimizes the risk of poor quality works; incorrect or faulty works being carried out and ensures that the works are done safely.

At Chem Spec, we have an experienced team able to review the specifications that will be required by the contractors onsite. With our NACE CIP qualified engineers, we can review existing specifications and add clauses and information in line with leading industry best practice.

Our primary role as coatings inspectors is to obtain, read and understand the specification and supporting documents; then observe, record and report on the technical aspects of a coating projects and conformance or deviation from the project specification. This ensures that the coating supplied matches the requirements of the job and/or industry; is applied according to the Product Data Sheet stipulations; and meets mandatory, statutory and SHE requirements.

During our onsite visit, we carry the following tests and offer specialised advise on;

  • Surface Preparation
  • Moisture tests
  • Climatic Conditions monitoring
  • Wet Film Thickness
  • Dry Film Thickness
  • Material Thickness
  • Adhesion tests
  • Pinhole and Porosity Tests
  • Concrete inspection

We service the following industries but not limited to;

  • Mining
  • Industrial
  • Pipeline
  • Chemical
  • Food Industry
  • Energy
  • Water & Waste Water

Coating job planning should and must be included at every stage of the building phase i.e. project design, application and maintenance stages. Chem Spec has a robust array of technical expertise in planning and forecasting, needs evaluation and specification consulting at your immediate disposal.

Paint or Solvent Spill Advice – Preventing Pollution

This information aims to assist people in the painting industry and to comply with their general environmental duty by preventing pollutants generated by their activities from entering the environment.

Paint and painting related pollutants are toxic to the environment. They can also poison animals and plants if they enter the storm-water system as it drains directly to our water sources without treatment.


On site

  • No material or wastewater should enter the storm-water system.
  • Check and note the location of storm-water drains.
  • Do not store any material within 10 metres of the storm-water system or in a place where it may enter the storm-water system.
  • Ensure a spill kit is available at all painting locations. Spill kits are commercially available and should be kept in a clearly labelled easy to get to place.
  • Develop a spill clean-up plan and make sure staff know what to do in the event of a spill. Prepare and practice your clean-up procedure. If a spill of paint, chemicals, or wastewater occurs in the storm-water system, stop the source, contain it and clean it up (do not use water, dry clean up only).
  • If the spill is too large to handle on your own or you don’t have the appropriate clean up materials, contact the Fire department for advice as soon as possible.
  • If you do have an accident and pollution occurs you are required to adequately clean this up.
  • If taking a break and returning to the project, the painting equipment may be wrapped in an impervious material such as a plastic bag to slow the hardening of the paint.
  • If the job is completed, return as much paint as possible from rollers, brushes and trays back into the paint containers and seal them.
  • Paint out any excess paint onto an absorbent material such as an old rag or newspaper, allow paint to dry then dispose appropriately.
  • Ensure you have a protected paint wash out area, for washing of all painting and/or other dirty equipment. Keep paint types such as water-based and solvent based paints separate.
  • For water based paints – Use one container of water to clean your equipment and another container to rinse. Water from the second container, which was used for rinsing, can be reused for cleaning equipment. – Place all wastewater from equipment cleaning into a larger drum and allow the solids to settle. There are also products available that treat paint wastewater allowing for easier disposal.

– Use an old rag or piece of newspaper and wipe out the paint solids from the container. Allow to dry before disposing.

  • For oil-based paints – Wash equipment in a series of solvent baths until clean. The solvent can be reused until it becomes saturated with paint. – Used solvent can be poured into a container for later use. An old rag or piece of newspaper should be used to wipe out the paint solids from the container. Allow the solids to dry before disposing appropriately.

– Solvents should be stored in labelled, sealed containers to prevent evaporation.

– You must dispose of waste solvent through a licensed hazardous waste contractor.

Do not place in a residential garbage bin or on the ground.
