Soudal Soudagum Hydro is the optimal solution for ensuring the durability and resistance of a myriad of surfaces. Boasting solvent-free and isocyanate-free properties, it's as environmentally friendly as it is robust. Its low viscosity formulation means it is easily spreadable on both horizontal and vertical surfaces, demonstrating excellent workability. As a ready-to-use, single-component waterproof coating, it offers excellent adhesion on most standard substrates, with two layers application giving a premium, evenly applied finish.
This powerful coating combats against the typical UK weather onslaught and is rain resistant merely 2 hours after application, making it a dependable choice no matter the weather. Its water vapour permeable nature helps to prevent blistering and peeling by allowing moisture to escape while blocking off-water penetration. Its excellent resistance gives it the ability to endure chemicals, UV rays, and a range of temperatures.
Soudagum Hydro also provides exceptional crack-bridging capabilities, ensuring the surface maintains its integrity over time. Upon drying, it forms a brilliant, tough, elastic seal that will endure the challenges of the elements. To cap it off, it can be painted over, granting the professional or DIY user the creative control over their project's final look.

Take the usual labour hygiene into account.
PPE should be worn during application. See our Safety & PPE Products.
Consult label and material safety data sheet for more information.
Excellent adhesion on many substrates such as concrete, screed, glass, ceramics, tiles and wood, also metals such as aluminium, steel, zinc and copper.
All Surfaces must be firm, loadbearing and free of dust and grease.
We always recommend a preliminary compatibility test.
Remove all traces of loose existing coating material. SoudaGum Hydro can be used without primer on moist substrates but not in the presence of stagnant water.
Open the lid and stir the product before using.
Apply by roller or brush in 2 layers to a thickness of 2mm (Recommended).
SoudaGum Hydro may be reinforced with a fleece lining such as Soudatextile.
The second layer cannot be applied until the first has dried completely.
After approximately 12 Hours the treated surface should be dry and follow-up work can begin.
Be aware that different environmental factors can influence the drying time.
Connection and expansion joints must be previously properly dimensioned in order to achieve optimal performance. Suitable backing material is essential (foamed polyethylene).
For optimal elastic characteristics of the sealant 2:1 or 1:1 width / depth ratio of the joint is suggested (minimal joint width: 6mm; maximal joint width: 20mm).
Approx 1.4kg/m² (Based on 1mm thickness) to 2kg/m² (Based on 2mm thickness).
This equates to approx 0.5m² - 0.7m² per kg.
