PAHTEL CERESIT CT 29 WEATHER-RESISTANT COARSE 5 KG

Ceresit CT 29 is a mineral-based jointing compound designed primarily for leveling walls made of brick or lightweight blocks. It can also be used to repair standard cement-lime plaster layers on interior and exterior surfaces of buildings, to fill deep defects (such as recesses created during installation work), and to smooth the surface of plaster. Thanks to its good moisture resistance, it can also be used in areas subject to constant moisture (bathrooms, basements) and for leveling the walls of swimming pools and water tanks, provided they are subsequently coated with a waterproofing compound. The properties of CT 29 allow for the application of a leveling layer 1–10 mm thick on walls and ceilings, which completely covers uneven and rough areas on concrete, brick, cement plaster, and cement-lime plaster surfaces. For spot filling, the maximum layer thickness is up to 50 mm. The recommended layer thickness in a single application is up to 5 mm, and the total thickness of all layers is up to 30 mm. • Ingredients: a mixture of cements with mineral fillers and modifiers • Bulk density: approximately 1.2 kg/dm³ • Density of fresh mix: approximately 1.89 kg/dm³ • Mixing ratio: 1.1–1.3 L of water per 5 kg • Application temperature: +5° to +25°C • Working time: up to 2 hours Surface preparation: CT 29 can be used on rigid, rough, dry substrates that have been cleaned of substances that prevent adhesion (e.g., lubricating oils, bitumen, dust): concrete, plaster, and exterior walls. Soiled areas, layers with low adhesion, materials that prevent absorption of the mixture, and paint residue must be removed beforehand. Substrates with low moisture content or uneven moisture distribution must be moistened with water beforehand. Before beginning the skimming process, the surfaces must be moistened, but they should be damp, not too wet. Dry substrates and those with high moisture absorption, especially walls made of aerated concrete or silicate blocks, as well as old concrete walls, should be primed with CT 17 and allowed to dry (approximately 2 hours). Application procedure: Pour the contents of the package into precisely measured, clean, cold water and mix thoroughly until a uniform, lump-free mixture is obtained. For larger quantities of CT 29, it is more convenient to mix the mixture using a mixer. When applying with a machine, use a screw pump or an automatic mixer with an integrated water dosing system. Spread the putty mixture evenly over the prepared substrate and then smooth it with a metal trowel. Once the material has set slightly, it can be smoothed with either a brush or a foam pad. To create a textured finish, use a special trowel with a felt pad moistened with water or a sponge to give the surface a textured appearance. After filling in any unevenness and allowing the putty mixture to dry, the entire surface must be leveled using a standard-consistency putty mixture. The leveled surface can be covered with a fine-grained finishing compound, a waterproofing compound, or ceramic tiles using a tile adhesive. CT 29 is also suitable for substrate preparation in ETICS systems. Storage: Up to 12 months from the date of manufacture, provided the product is stored on pallets in dry conditions and in intact, undamaged original packaging. Health and Safety Requirements: CT 29 contains cement, and mixing it with water causes an alkaline reaction. Therefore, protect your skin and eyes while working. If the mixture comes into contact with your eyes, rinse them immediately with plenty of water and seek medical attention.
