Stormdry MAX Enhanced Waterproofing Barrier

A row of houses. An orange glow emanates from the walls, ceiling and windows.

Heavily cracked walls in areas prone to graffiti and severe weather conditions demand maximum protection.

Stormdry MAX Enhanced Waterproofing Barrier bridges cracks, and waterproofs to a higher specification than Stormdry Masonry Protection Cream.

Stormdry MAX Enhanced Waterproofing Barrier makes surfaces resistant to graffiti and easy to clean.



Bridge large cracks

Bridges cracks up to 0.6mm

Everything from material corrosion to structural movement can cause cracks in masonry walls. Whatever the cause, cracks in walls allow moisture and rainwater to cause even greater damage. Stormdry MAX bridges cracks up to 0.6mm in width to keep damaged substrates dry.

Stormdry MAX is suitable for minor wall repair and renovation jobs:

  • Brick veneer cracks
  • Vertical brick cracks
  • Horizontal brick cracks

Remove graffiti with ease

Stormdry AG - Graffiti removal with jet wash

Stormdry MAX lasts for longer than competing anti-graffiti coatings. It actively repels fly posters and sticker adhesives.

Stormdry MAX cures to a hydrophobic coating that turns aerosolised paint particles back into liquid droplets on contact. This prevents ink and pigment from permeating the substrate, making it easy to wipe away.

Ensure any paint, marker pen, stickers or fly posters can be easily removed without ghosting or residue on porous substrates. As colour pigments cannot absorb through Stormdry MAX, you can reset vandalised walls back to a mark-free surface with little effort.

Graffitied substrates can be easily cleaned using a:

  • Pressure washer
  • Scouring pad
  • Wet cloth

Stormdry MAX requires a relatively low level of pressure to remove graffitied surfaces, helping to preserve and care for delicate and damaged substrates. No warm water, extra cleaners or high-pressure washers are needed for a perfectly clean surface.

Superior waterproofing protection

Stormdry MAX beading

Stormdry MAX can be used in conjunction with Stormdry Masonry Protection Cream and Stormdry Repointing Additive No.2 as part of an effective flood defence design.

Together with Stormdry MPC, Stormdry MAX forms a physical durable barrier that fills cracks in the substrate.


Increase and retain:

  • Resilience against water penetration
  • Substrate drying speed
  • Pre-flood building condition

Quick and effortless application

Stormdry MAX cures quickly on air contact. Touch dry after 2 hours and tack-free after 4 hours. Forms a fully waterproof, crack-bridging and anti-graffiti coating in a single coat. 

Application does not require unique equipment – use a standard brush or roller. Stormdry MAX cures to a semi-gloss finish.

UV resistant. Shield a wide range of substrates
