Envirograf EP/CP White Intumescent Paint for Plaster

Introducing EP/CP White Intumescent Coating from Envirograf to gain up to 60 minutes fire protection

Introduction:

EP/CP White Intumescent Paint for plaster is a white, fire-resistant coating system, offering fire protection to plasterboard or lath-and-plaster ceilings and walls of various thicknesses. Provides an excellent solution for projects where plasterboard features are in need of fire rating but cannot be replaced, as is often the case in listed buildings. When attacked by fire, the intumescent material protects the integrity and insulation of the coated surface.

Application Rate 8m2 per litre per coat:  1 litre will cover 4m2

Advantages:

–  Designed for application to 9½mm or 12½mm thick plasterboard, 18mm & thicker lath-and-plaster, or concrete walls and ceilings, providing 1 hour of integrity and insulation

– Can be used to protect and insulate concrete and also insulate steelwork within a layer of concrete

– Dries to a smooth or stippled decorative finish

– An ideal solution for upgrading the fire rating of original features in Graded historical buildings

Application Instructions:

Clean all walls or ceilings, taking off any loose paint and removing all wall or ceiling paper. Any grooves or cracks in the ceiling or walls can be made good with Envirograf® Intumescent Cement – Product 63 or AM Intumescent Mastic – Product 58. Should it be found that EP/CP will not adhere to the existing coating, then apply 1 coat of Envirograf® HWAP Adhesion Primer at 10m² per litre. Then apply 2 coats of EP/CP at the rate of 8m² per litre, per coat. The approximate drying time is 1 hour. EP/CP is a smooth coating, but if you require a comb finish or a stippled look, then apply 1 coat of EP/CP at 8 m² per litre, followed by 1 coat of AB – Product 96 – this is a thicker version of EP/CP, which can be comb finished. Please contact us for a quote.

EP/CP and AB both need a Top Finish Coat. We recommend the usage of Envirograf® HW Acrylic Coating at 10 m² per litre, per coat. Please contact us on 01752 690997 if you would like this to be coloured to a specific RAL or BS colour code.

Envirograf® HW Excel can also be applied to EP/CP, if a satin or gloss finish is desired. This comes in white as standard, although it can also be tinted to RAL or BS colour codes. Please contact us to order a tinted version.

HW02/E can be applied where cornices have gold leaf on them. The application rates are – 3 coats at 8 m² per litre, per coat. 1 coat of BL/TCW topcoat should then be applied at 8-10 m² per litre. Please contact us for a quote on these products.

How does the intumescent protect the plaster:

Envirograf EP/CP White Intumescent Paint for plaster surfaces, protect plaster by undergoing a chemical reaction when exposed to high temperatures, such as those encountered during a fire. Here’s a detailed explanation of how this protection works:

Expansion:

Upon exposure to heat, intumescent paint expands to many times its original thickness. This expansion process creates a charred layer or barrier.

Insulation:

The expanded layer acts as an insulating barrier that protects the underlying material—plaster, in this case—from the heat of the fire. This insulation significantly slows down the rate at which heat transfers to the plaster surface, thereby reducing the risk of the plaster catching fire or deteriorating under extreme heat.

Integrity and Stability:

By insulating the plaster from heat, the intumescent coating helps maintain the structural integrity of the wall or ceiling. This is particularly important in buildings where maintaining the stability of plaster walls or ceilings is crucial for the overall structural integrity during a fire.

Fire Resistance:

The protective char layer formed by the intumescent coating can withstand fire for a specified period, often ranging from 30 minutes to several hours, depending on the product and the thickness of the application. This provides valuable time for evacuation and for emergency services to respond.

Aesthetic Preservation:

For historical buildings or in cases where the aesthetic of the plasterwork is important, intumescent coatings offer a way to enhance fire resistance without altering the appearance of the plaster surfaces. The paint can be applied like a regular paint and, under normal conditions, does not affect the look of the plaster.

This combination of expansion, insulation, and the creation of a protective barrier makes intumescent coatings an effective solution for enhancing the fire resistance of plaster surfaces, thereby contributing to the overall fire safety of buildings.
