Intumescent paint coatings finish standards
A variety of finish standards can be achieved depending on the look desired and the available budget. Naturally a higher level of finish is going to be more labour and material intensive and will therefore cost more.
The level of finish, however, has no bearing on the achieved FRL.

intumescent paint coating anatomy
This diagram shows the recommended coatings over mild steel. Consult with the intumescent paint coating manufacturer for their approved primer and topcoat... these vary from product to product.
All surfaces should receive an abrasive blast to SA2.5 prior to applying the approved primer.
Always refer to the relevant technical datasheet prior to use to ensure a product is suitable for your application.
Visit the manufacturer's website to find the relevant datasheet or check our own library of datasheets that are regularly udated.
