WIDOSEAL-LF 1K

WIDOSEAL-LF 1K is a solvent-free, one-component liquid waterproofing for flameless application on flat roofs and balconies, detailed connections, structural waterproofings and special solutions. The material basis of WIDOSEAL-LF 1K is an SMP.

The material has been tested at the highest performance levels in accordance with the European guidelines for liquid-applied roof waterproofings (ETA-24/0499 according to EAD 030350-00-0402).

In addition, it has been tested according to PG-FLK and PG-FBB. WIDOSEAL-LF 1K achieved the corresponding general building inspectorate test certificates for structural waterproofing of areas in contact with the ground. Thus, it may also be used at floor to ceiling windows and in basement areas.

During processing and curing, the material is nearly odour-free. The EMICODE-classification of EC 1 Plus confirms the low odour impact.

Polyester fleece G120 is used as reinforcement. The reinforcement determines the breaking strength and elongation at break and ensures an even layer thickness. The overlap of reinforcement layers must be at least 5 cm. The overlap to other materials is to be determined for each case separately, but should not be less than 10 cm.

Surface preparation

WIDOSEAL-LF 1K adheres without priming to many surfaces which are dry (max. 5% dampness), free from grease/oil, loose parts and other materials which may lower the adhesion. Surfaces that require priming, as well as general information on surface preparation, can be found in our references for priming. You may also seek advice from our application engineers.

Application

There is a foil on the material within the bucket, which has to be removed before using the material. Then, the material needs to be stirred thoroughly with a slowly rotating agitator. Then, 2/3 of the waterproofing material is applied onto the prepared surface with a paint roller. Afterwards, the Polyester fleece is embedded into the wet material, and the remaining 1/3 of the material is applied onto the fleece using the paint roller. Once the container has been opened, the material should be used up swiftly. Should the material form a thin firm layer, which can easily be removed, and the remaining material may be used up.

Additional coatings may be applied within 24 hours without any further preparation. After 24 hours, the surface needs to be roughened before a further layer may be applied. Alternatively, areas that may need additional coatings can be sprinkled with quartz sand while the first layer is still wet.
