Technical Datasheet THERMOPAL®-ULTRA-white Substrate preparation Requirement for substrate 1. Free of adhesion inhibiting substances 2. Pore open 3. Load-bearing
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 whole area with 100% coverage.
Usage Measures depending on the degree of salting in accordance with WTA
Mixing 1. 2. 3. 4.
Pour the required quantity of water into a clean mixing bucket. Completely add the powder and mix until homogeneous and free from lumps. The mixing time is ca. 3 minutes. After a short activation time, stir again.
Application 1. 2. 3. 4. 5. 6. 7.
THERMOPAL®-ULTRA-white can be applied in a single application step bis 30 mm layer thickness on the surface. For thicker layers, render in several layers. In this case, strike off the previous layer with a plasterer’s darby, and immediately after stiffening, roughen up horizontally and allow to dry. Removal takes place using a suitable tool (float, trowel or plasterer’s darby), depending on the application, within the pot life. After sufficient standing time, the surface may be felt boarded matt damp or rubbed down. Alternatively, the surface can also be treated with a grid float. Grid floating is performed depending on the ambient conditions. If necessary, the plaster surface can be overcoated after one day with THERMOPAL® FS33 fine mortar.
Storage conditions Storage Store in a cool and dry place. Min. 9 months in the original canister. Promptly use opened canister.
Disposal Product leftovers can be disposed of in accordance with disposal code AVV 17 01 01.

Technical Datasheet THERMOPAL®-ULTRA-white Notes Protect surfaces that are not to be treated from the effects of THERMOPAL®-ULTRA-white! Very damp substrates may require longer waiting times before they can be rubbed off. 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). With difficult site conditions (e.g. inhomogeneous masonry work, waterproofed masonry work, use in exerior 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. Rubbing prematurely or too intensively causes a binder concentration on the surface and can cause stress cracks. Observe the WTA "Restoration plaster systems" data sheet for planning and implementing of restoration measures. Protect from strong solar radiation and draughts. Highly vapour permeable dispersion silicate paints must be used for the colour design.
