Yki rouhepinnoite - Rough Coating
|DESCRIPTION||Water-based, alkali-resistant and water-repellent acrylate coating.|
For plain concrete substrates and screeded surfaces of concrete and masonry structures in socle and wall surfaces. Also suitable for building boards. The screed should be a cement or cement-rich lime-cement mortar. Minimum grain size approx. 2 mm.
|RECOMMENDED USES||Residential, business and industrial buildings, warehouses etc.|
|Base paints||RPA and RPC|
|Colour Range||Tikkurila Colour Card for Exterior Paints and Facade Colour Card|
|Coverage||0.6-0.8m²/ l. Coverage is determined by the roughness and porosity of the surface, the painting method and painting conditions.|
|Can sizes||9 l|
|Mixing ratio||If necessary thin up to 1% with water.|
Trowel, for spray application, use plaster pump, min. nozzle size 5 mm or funnel sprayer. Coating applied with trowel is finished with Tikkurila plastic float. Sprayed coating can be left as such or finished with Tikkurila plastic float.
|Drying time at 23°C and 50% relative air humidity||
Touch-dry the following day
|Water vapour resistance (EN ISO 7783-2)||
sD,H2O < 0,2 m
|Water permeability (EN 1062-3)||
w24 < 0,2 kgm-2h-0,5
|Adhesion||> 0,8 N/mm2 (on concrete)
|Particle/grain size||Minimum grain size approx. 2 mm.
|Weather resistance||Good, even in industrial and maritime atmospheres. Prevents penetration of rain and splashes into the construction (water repellent) and, at the same time, allows passage of water from inside as vapour (good water vapour permeability).|
|Solids volume||Approx. 70 %.|
|Density||Approx. 1.8 - 1.9 kg/l, ISO 2811|
|Storage||Protect from frost. Temperature of the product or can may not exceed +35 °C. Not to be stored in sunlight even under a cover. A tinted coating or a coating in a poorly closed or incomplete can does not sustain long-term storage|
|Application conditions||The surface to be treated must be dry, the temperature of the air at least +5˚C and the relative humidity of the air below 80 %. Do not apply paint under strong sunlight.|
|Preparation||The substrate has to be solid enough, dry and hard before finishing.
Remove dirt, dust and salts from unpainted surfaces. Wash down mouldy or moss-covered surfaces with Homeenpoisto Mould Removal according to the instructions. Smooth and glass-like concrete surfaces have to be mechanically processed to create sufficient texture and to remove cement paste. Level block surfaces and uneven concrete surfaces with Yki Värilaasti, Tintable Render for Socles or Yki Levelling Mortar according to instructions.
Previously painted surface:
Remove dirt, dust and salts. Wash down mouldy or moss-covered etc. surfaces with Homeenpoisto Mould Removal according to the instructions. Remove flaking, poorly attached paint coats. Choose the removal method according to the strength of the substrate and the type of paint to be removed (e.g. steel brushing, high pressure washing with hot water or water-sand-washing).
Necessary leveling will be made with Yki Värilaasti, Tintable Render for Socles or Yki Levelling Mortar according to the instructions of the product data sheet.
|Priming||The substrate is recommended to be primed with Tikkurila Silicone Primer to avoid the breakthrough of e.g. salts.|
|Coating||Stir Yki Rough Coating well before use.
Application by steel trowel:
Apply by steel trowel a coat as thick as the grain size at a time to an area of approx.1 m². Grind the surface immediately (max. after 15 min.) by pressing lightly with Tikkurila plastic float. If the float does not move lightly, there is too much of coating. Remove the excess coating with a steel trowel. Adjust limits of pauses and borders of various cans to an unobtrusive spot.
Application by spraying e.g. with a plaster pump or a funnel sprayer:
Apply by spraying from approx. 1 m distance in a circular motion upright with the surface. Uniform surfaces are sprayed without interruption. Sprayed surface can be left as such or it can be grinded with a Tikkurila plastic float (see application with a steel trowel). The grinding work is started immediately (max. after 15 min) after spraying by pressing lightly with Tikkurila plastic float.
|Surface treatment||Note: If different batches are used, coat the boundary with a solution of 1 part of old batch and 1 part of new batch. Adjust limits of pauses and borders of various cans to an unobtrusive spot.
Protect windows before priming and coating. Clean possible splashes immediately from the windows.
Yki Rough Coating is not suitable for coating of horizontal surfaces of e.g. cold retaining walls or other similar horizontal surfaces.
|Cleaning of tools||Clean tools with water. To remove hardened paint, Tikkurila Pensselipesu (Tikkurila Tool Brush) is recommended.|
|Maintenance instructions||Dirty surface can be pressure cleaned carefully without detergent after one month from treatment at the earliest. Cleaning might leave an imprint, thus the washing area must be lined unnoticeably according to the lines of the structure. Loose dry dirt is recommended to remove lightly with a soft brush without rubbing.
Homeenpoisto Mould Removal and thorough rinsing can be used for the removal of alga and mould according to the instructions. NOTE! After mould removal the surface always requires a new treatment.
|Maintenance treatment||Yki Paint for Socles is suitable for maintenance painting. Kivisil Façade Paint or Yki Rough Coating applied by spray are suitable for façade maintenance painting (see Pretreatment, Priming and Coating|
|EU VOC 2004/42/EC-limit value||(Cat A/c) 40g/l(2010) Yki Rough coating contains VOC max. 40g/l.
