Technical data sheet THERMOPAL®-GP11 Preparing the surface 1. Remove old, damaged plasters, paints or coatings from the substrate up to 80 cm above the visible damaged area or the area delimited through inspections. The substrate must be prepared so that it is load-bearing. 2. Pre-treat it with ESCO-FLUAT in case of salt contamination. Apply a semi-covering splatterdash coat of THERMOPAL-SP as a bond coat (degree of coverage approx. 50%). In conjunction with mineral waterproofing slurries, apply the adhesive splatterdash coat over the entire surface with 100% coverage.
Application Measures depending on the degree of salting after WTA
Mixing 1. Pour the required quantity of water into a clean mixing bucket. 2. Completely add the powder and mix until homogeneous and free from lumps. 3. The mixing time is ca. 3 minutes.
Application 1. THERMOPAL®-GP11 can be applied in a single application step §A_PIM_Applikationsverfahren_Max_Schichtdicke_pro_Arbeitsgang§ layer thickness on the surface. 2. For thicker layers, render in several layers. 3. In this case, strike off the previous layer with a plasterer’s darby, and immediately after stiffening, roughen up horizontally and allow to dry. 4. 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®-GP11! Very damp substrates may require longer waiting times before they can be rubbed off. Protect from strong solar radiation and draughts. Observe the WTA "Restoration plaster systems" data sheet for planning and implementing of restoration measures. With difficult site conditions (e.g. inhomogeneous masonry work, waterproofed masonry work, use in exterior area under changing weather conditions and thick-layer plaster build-ups, etc.), an alkali-resistant glass scrim with a mesh size of 7 × 7 mm or 10 × 10 mm can be used to increase the cracking resistance. The inlay of the plastering fabric is applied in the upper third of the plaster layer. With low strength substrates, a corrosion-resistant plaster base must be attached mechanically to the substrate prior to plastering. (Cannot be used with internal waterproofing).
