Technical data sheet THERMOPAL®-SP Application Measures depending on the degree of salting after WTA
Mixing 1. Put the water into a clean mixing bucket and mix with the powder component with a stirrer to produce a homogeneous, lump-free mass. 2. The mixing time is ca. 3 minutes.
Application 1. The material is applied in a net shape for subsequent plaster build-ups with restoration plasters. (degree of coverage ≤ 50%) 2. The application must cover the whole area for subsequent applications with mineral waterproofing slurries or quarry stone substrates. 3. The splatterdash coat should only be applied thinly, max. 5 mm.
Storage conditions Storage Store in a cool and dry place. Min. 12 months in the original canister. Promptly use opened container.
