PLASTERING MIX
FOR 0 TO III GRADE PLASTERS
FOR INTERNAL AND EXTERNAL USE
|
| AVAL KT 111 PLASTERING MIX is an enhanced cement mixture of M4 class designed for making traditional plasters of 0 to III grade, interior and exterior. It is available in two versions: for manual and mechanical plastering – packaging additional marked with M. Rough surfaces made of bricks, blocks, hollow bricks and other similar ceramic or lime-sand materials can serve as substrate for the mortar. It can also be used on concrete, aerated concrete, chip-cement boards, cement plaster, cement-lime plaster and gypsum surfaces. It is suitable for internal and external use with maximum layer thickness of 6÷30 mm. |
 |
|
| AVAL KT 111 PLASTERING MIX is a ready-to-use dry mix based on top-quality cement binder, quartz fillers and improvers. Owing to specially selected parameters, it is convenient to use and plastic and is characterised by good adhesion to the substrate. It is frost- and water-resistant. |
|
|
| The substrate should be dry, stable, even and structurally sound i.e. strong enough; it should be free from anything that may weaken mortar adhesion, in particular dust, dirt, lime, oil, grease, wax, remains of emulsion and oil paint. Hammer off poorly adhering elements and remove loose pieces using a steel brush. Immediately before plastering, wet the substrate with clean water. If necessary, use AVAL KT 17 priming emulsion to reduce substrate`s excessive absorption. Do not use the plastering mix for wooden, metal and plastic substrates. Before plastering of gypsum substrates scratch the wall face with a sharp chisel, making a diagonal dense pattern, where the scratches` depth should be ca. 3 mm. Before plastering of chip-cement boards, cover the board contact area with belts made of a metal mesh. |

|
| In order to prepare the mortar, pour dry mortar into a container with suitable amount of water (in proportion: 0.13÷0.16 l water for 1 kg of dry mortar) and mix until homogenous. It is best to mix it mechanically, using a drill with a mixer or in a concrete mixer. In case of mechanical plastering, use a plastering unit. The mortar is ready to use several minutes after mixing. It maintains its properties for 4 hours. Adjust the ratio of added water experimentally, following the desired consistency of the mortar, type of substrate and weather. Inappropriate amount of water for mass preparation results in deterioration of strength parameters of the plaster. |

|
| Apply the plaster in two layers. Use plastering boards to obtain even plaster surface. They can be fixed mechanically or by placing into the mortar (mesh boards). The first plastering stage is “initial rendering coat.” After it sets (but still before hardening), prepare “surface floating coat.” Plaster in both stages is applied evenly using a trowel (or a plastering unit). Collect the excess of the mortar using a float made of foamed polystyrene or wood and put back into the container. Even fresh plaster using a long rule and screeds. The moment when float finish is to be commenced needs to be determined experimentally so that the plaster does not dry too much. Float finish usually is done after application of an additional thin mortar layer corresponding to aggregate thickness. Conduct finishing work in accordance with plastering work technology, using tools appropriate to intended use of the plaster and to obtain a given finishing effect. If the plaster is to be used as the substrate under ceramic facing, do not float it. If the plaster is to be used as the substrate for gypsum finish coat, smooth it with a float made of foamed polystyrene. When internal plasters dry, ensure appropriate room ventilation. Protect external plasters from drying too quickly e.g. by sprinkling with water. The information comprises basic instructions of product application and do not relieve users of responsibility for work in accordance with good construction practice and OHS regulations. |
