Technical data sheet THERMOPAL®-FS33 Preparing the surface 1. 2. 3. 4.
Shrinkage processes in the restoration plaster must be largely completed. Extremely absorbent and slightly sandy substrates must be primed with AQUAFIN-Primer. The primer must be completely dry / must have reacted fully before the subsequent work steps are carried out. No primer is required for applications on THERMOPAL-SR24, THERMOPAL-SR44 or THERMOPAL-ULTRA.
Application Mixing 1. Pour THERMOPAL®-FS33 into a mixing bucket with clean water (Technical Data > water addition) and mix with a mixer until free from lumps. 2. The mixing time is ca. 3 minutes.
Surface levelling 1. Apply the levelling compounds in the required layer thickness. 2. The surface can be rubbed down using a Rubber squeegee, felt or sponge board after a corresponding waiting time. 3. Allow one day standing time per 1 mm of layer thickness.
Storage conditions Storage Store in a cool and dry place. Min. 12 months in the original canister. Promptly use opened container.
Disposal Product residues can be disposed of in accordance with disposal code AVV 17 01 01.
Notes Protect surfaces that are not to be treated from the effects of THERMOPAL®-FS33! When carrying out plastering work, DIN18350 and DIN V 18550 must always be observed. The plaster surface should be free of cracks after complete drying. Hairline cracks/shrinkage cracks without hollow layers are, however, harmless and do not impair the technical properties. If water is extracted too quickly (heated rooms or highly absorbent substrates) or if plaster substrates are not sufficiently dry, there is a risk of cracking! Do not add water or new mortar to existing THERMOPAL®-FS33 mortar that has already set in order to make it workable again. (Risk of inadequate strength development) Very damp substrates may require longer waiting times before they can be rubbed off. Very high air humidity must be avoided by taking suitable measures, e.g. using condensation dryers, ventilating etc. However, direct heating or draughts should be avoided. Protect from strong solar radiation and draughts. Highly vapour permeable silicate paints must be used for the colour design. Rubbing prematurely or too intensively causes a binder concentration on the surface and can cause stress cracks.
