Stormdry MAX Enhanced Waterproofing Barrier is a clear, moisture-curing gel coating that protects external surfaces from water ingress, graffiti and fine cracks. It is suitable for use on masonry, stone, concrete, selected metals and painted surfaces. When used on cracked substrates, it bridges gaps up to 0.6 mm, helping to prevent penetrating damp.This treatment is particularly useful on walls previously coated with Stormdry Masonry Protection Cream, forming a complementary topcoat where fine surface cracking is present. When used in anti-graffiti applications, the coating can withstand up to 15 cleaning cycles before recoating may be required. It also contributes to low-level flood resistance when used in conjunction with appropriate repointing materials.Stormdry MAX provides a partially breathable, semi-gloss finish that becomes less visible over time. It is applied by brush or roller and dries to a clear film. Application requires dry surfaces and dry weather for at least 24 hours. For best results, the product should not be applied to fragile or salt-contaminated substrates and is intended for use above the damp-proof course.
