Primer Sealer Paint. Oil based. COSHH Assessment Form

A pre-filled COSHH Assessment Form for Oil-based Primer and Sealer, with some example text reading:

Fire details:

Extinguishing media: Foam, CO2 or Dry Powder are recommended.

Not to be used – water jet.

Recommendations: Fire will produce dense black smoke. Exposure to decomposition products may cause a health hazard.

Firefighters should wear self-contained breathing apparatus.

Closed containers exposed to fire should be cooled with water. Do not allow runoff from firefighting to enter drains or watercourses.

An oil-based primer sealer is a specialised type of paint that serves dual purposes: it acts as both a primer and a sealer, particularly designed for sealing porous surfaces and preparing them for subsequent paint applications. Formulated primarily with oil, this type of primer offers several key benefits, including robust durability, superior adhesion, and the capacity to inhibit moisture from penetrating the underlying material.

One of the standout features of oil-based primers is their ability to effectively seal porous surfaces, such as wood. By forming a protective barrier, they prevent the paint from being excessively absorbed by the substrate, which results in a smooth and even finish that enhances the final appearance of the painted surface.

Moreover, oil-based primers excel in promoting strong adhesion between the primer and the topcoat of paint. This adherence is crucial for ensuring that the paint layers bond effectively, thus increasing the longevity of the finish.

In addition to their adhesive properties, oil-based primers are particularly adept at blocking out stubborn stains, such as tannins found in certain woods, thereby preventing these blemishes from bleeding through to the topcoat and compromising the final colour and quality of the paint job.

Renowned for their durability and long-lasting performance, oil-based primers can be applied to a variety of surfaces, including wood, metal, and previously painted surfaces, making them a versatile choice for both interior and exterior projects. Their ability to withstand environmental challenges, along with their reliability in promoting an optimal painting experience, makes oil-based primer sealers a preferred option among professionals and DIY enthusiasts alike.
