Products > Belzona 3000 Series ~ Polymeric Membranes for Waterproofing & Weatherproofing Buildings, Structures and Insulation

A range of liquid-applied waterproofing membranes for the repair and protection of buildings and structures, and for the fire retardant encapsulation of insulation materials.

Belzona 3000 Series - Polymeric Membranes Belzona 3111 Flexible Membrane A water-based, thick liquid that dries to a flexible film. It is ideal for waterproofing and weatherproofing problem areas of buildings and structures. Does require a conditioner and Belzona 9311 (3111 Reinforcing Sheet) where durability is required. Typically applied in two coats

Belzona 3000 Series - Polymeric Membranes Belzona 3121 MR-7 A two part, elastomeric material used for waterproofing roofs, parking decks, and other structures. This material is excellent for emergency situations and will cure under wet and/or freezing conditions. Can be applied directly to damp surfaces or poured through standing water to seal leaks. A typical coating application on a smooth surface would be a two-coat system at 15 mils per coat. Where possible, Belzona 9331 (3121 Reinforcing Sheet) should be used for added durability. A conditioner is not required.

Belzona 3000 Series - Polymeric Membranes Belzona 3211 Lagseal A water-based liquid used for a flexible yet seamless seal around all types of insulation. Has a Class A Fire Rating. Ideal on pipes, boiler insulation, and may be used around turbines to prevent oil penetration into insulation. The finished coating is micro-porous, which allows moisture from condensation to escape, but prevents water, oil, or other fluids from penetrating the surface. A surface conditioner is required only when sealing from insulation to another surface such as to a metal pipe surface or masonry wall. Typically applied in a 2-coat system

Belzona 3000 Series - Polymeric Membranes Belzona 3911 PSC Conditioner A one part, solvent based surface conditioner for use on all porous and bitumin.ous surfaces such as concrete, masonry, wood, asphalt, and min.eral felt. The coverage rate varies greatly with substrate porosity.

Belzona 3000 Series - Polymeric Membranes Belzona 3912 Water Based Conditioner A one part, water based formulation for porous and bitumin.ous surfaces, excluding asphalt. It is ideal for areas where no solvent based materials may be used due to either safety or regulatory requirements. The coverage rate varies greatly with substrate porosity.

Belzona 3000 Series - Polymeric Membranes Belzona 3921 GSC Conditioner A two part, solvent based surface conditioner for use on non-porous surfaces such as: concrete, masonry, wood, asphalt, min.eral felt, metals, glass, or slate. The product has a high zinc-epoxy content making it suitable for application to galvanized metal surfaces and small steel protection applications such as exposed re-bar in concrete.

Belzona 3000 Series - Polymeric Membranes Belzona 9311 Reinforcing Sheet for 3111 A man-made specially woven, open mesh fabric designed for use with Belzona 3111/Flexible Membrane. This sheet provides added durability and strength, and should be used in virtually all Belzona 3111/Flexible Membrane applications. The special weave allows for even, lengthwise ripping to any desired width.

Belzona 3000 Series - Polymeric Membranes Belzona 9321 Reinforcing Sheet for 3211 A closed mesh fabric designed for use with Belzona 3121/MR-7. This sheet provides added durability and strength to Belzona 3121/MR-7applications.

Belzona 3000 Series - Polymeric Membranes Belzona 9331 Reinforcing Sheet for 3121 An open weave, bonded fiberglass mesh that resists "shredding
