Firestop Putties

Firestop putty is a fire-resistant sealant commonly used to fill gaps and voids in walls, floors, and ceilings. It is designed to prevent the spread of fire and smoke through penetrations in fire-rated barriers, such as those found in commercial buildings, hospitals, and schools. Firestop putties come in various forms, including pre-mixed putties and those that require mixing before application.

The Benefits of Using Firestop Putties:

Firestop putties offer several benefits, including:

Fire Resistance: Firestop putties can withstand high temperatures and prevent the spread of fire for up to four hours, making them a vital component of fire protection systems.

Easy to Apply: Firestop putties can be applied quickly and easily using a putty knife, which makes them ideal for sealing small gaps and penetrations.

Cost-Effective: Firestop putties are cost-effective compared to other fire-resistant sealants, such as intumescent coatings.

Versatile: Firestop putties can be used on various substrates, including concrete, wood, and metal.

Types of Firestop Putties:

There are several types of firestop putties available in the market, including:

Intumescent Firestop Putty: Intumescent firestop putty expands when exposed to heat, creating a barrier that prevents the spread of fire and smoke.

Non-Intumescent Firestop Putty: Non-intumescent firestop putty does not expand when exposed to heat. Instead, it forms a rigid, fire-resistant barrier.

Water-Based Firestop Putty: Water-based firestop putty is a non-toxic and environmentally friendly option that is easy to clean up.

Application of Firestop Putties:

The application of firestop putties is straightforward and involves the following steps:

• Clean the surface to be sealed thoroughly.
• Apply the firestop putty using a putty knife or caulking gun.
• Smooth the putty to ensure a tight seal.
• Allow the putty to dry and cure according to the manufacturer's instructions.

Firestop putties are an essential component of fire protection systems, and they offer several benefits, including fire resistance, ease of application, cost-effectiveness, and versatility. With various types of firestop putties available, it is essential to choose the right one for the job and follow the manufacturer's instructions for application and curing.
