Product Description

It is easily applied both horizontal and vertical surfaces, cross-linking at ambient temperatures to form a flexible product. Seals formed with Neutral Sealant remain unchanged even after many years of exposure to climatic extremes, industrial pollution, sudden temperature change and water. It remains flexible at temperatures from -40°C to +150°C. Neutral Sealant adheres perfectly to most surfaces used in building without needing a primer. Apply Primer PL first on different and compatible plastic materials.

Field of Application

Neutral Sealant is a solvent-free, neutral silicone sealant with a low modulus of elasticity, specific for sealing fillet joints between tinwork accessories and layers of waterproofing material. It is particularly recommended for metals normally used on roofs and flat roofs such as steel, zinc and pre-painted sheet, anodized and pre-painted aluminum and copper. The chemical characteristics of the product also make it perfectly suitable for absorbent materials such as concrete, cellular concrete, brickwork, varnished and lacquered wood and various compact, non-absorbent materials such as glass, ceramic, clinker, enameled surfaces, water and solvent-based paint and plastics such as polycarbonate: we recommend always carrying out a preliminary test. Thanks to its broad spectrum of adhesion and low modulus of elasticity, Neutral Sealant is also suitable for sealing fillet joints in tinwork accessories such as:

· downpipes;

· guttering;

· flashing;

· gables;

· metal flat roofs;

· corner guards;

· special shaped pieces;

· heads of rivets and fasteners.

Application Procedure

Preparation of substrate

Surfaces to be sealed must be dry, de-greased, solid and free of dust, loose parts, oil, grease, wax, old paintwork and rust on metal surfaces. We recommend applying masking tape along the edges of the joint in order to avoid the sealant seeping out of the joint and to get a more attractive finish.

Preparing the product

Ready to be used.

Applying the product

Insert the cartridge in an extrusion gun, cut off the tip of the cartridge, screw on the extrusion nozzle, trim the nozzle at an angle of 45° and according to the extruded width required and squeeze out the product in a continuous flow into the joint while trying to avoid air entering the joint. Immediately after applying the sealant, smooth over the surface before it hardens with a spatula wetted with soap and water. Remove the masking tape immediately after smoothing over the sealant
