Roof Seal Cracks and Edging Sealer

Name: Roof Seal Cracks and Edging Sealer

A one part, high quality, flexible material for use with Roof Seal Liquid Membrane. Based on hybrid technology this product can be applied to wet surfaces and is non-shrinking making it ideal for use as a gap-filler where cracks and apertures exist in the roof substrate to be covered.

Features: High modulus, remains permanently flexible. – For exterior applications in all weather conditions. – Non-shrinking. – Contains no isocyanates, solvents, silicone and phthalates. – Rapid curing. – Excellent adhesion to most surfaces (even moist surfaces). – Wet on wet application. – No odour.

Application: It can be used prior to application of Seal It Roof Seal Membrane to make good any cracks, edges, details and other openings in the substrate to give a sound base. Suitable for use with most common roofing materials offering superb adhesion. Alternatively it can also be used after application to secure edgings and seals to create a self- terminating flashing or provide extra protection around roof elements such as chimneys, air vents etc.

Instructions: Preparation: Ensure all surfaces are clean and free from grease, oil or any other contaminants that may hinder adhesion.
Application: Carefully cut the top of the cartridge taking care not to damage the threaded area. Screw on the nozzle supplied and cut at an angle approximately 45°. Apply using a standard sealant gun. Apply in a continuous bead along the area. Smooth by tooling with
a soapy solution and once cured rinse with clean water before applying RoofSeal. Remove any excess material and clean tools immediately with white spirit. Replace plastic cap after use. RoofSeal can be applied over the filled gaps and cracks approximately 8 hours after application of sealant/filler, or once the filler has skinned sufficiently so that it will not be damaged during application of the coating.

Limitations: It is imperative that the sealer and ROOF SEAL are not applied over 5 days apart from each other. Adhesion between the two products will be affected if applied after 5 days. It is essential that bitumen surfaces and roof felts, etc. are properly and completely primed
using ROOF SEAL BLEED BLOCKER before application or product failure WILL occur.
Do use with expansion joints or for installations where the joints are continually immersed in water. Note: not suitable for use on LSE plastics such as PE, PP and PTFE
