Application and Substrate Preparation


<h1 class="border">Application and Substrate Preparation</h1>
<h2>Architectural Colours</h2>
<h2>Marmur Lime Plasters</h2>
<p> Following the correct instructions about surface preparation MARMUR may be applied over: </p>
<ul>
  <li>Lime and Cement Mortars</li>
  <li>Premixed Renderings</li>
  <li>Pre-Existing Lime and Gypsum Plasters</li>
  <li>Moisture-Permeable plasters</li>
  <li>Gypsum Plasterboard</li>
</ul>
<h2>Substrate Preparation</h2>
<p> The substrate must be perfectly dry, dust-free, with no humidity and salts stains. </p>
<ol>
  <li> New natural lime plasters: the substrate should "mature" for a period of minimum  20 days; then apply MARMUR lime plaster and wet thoroughly the wall in case of windy and extremely hot weather. </li>
  <li> New or recent lime and cement mortars, premixed renderings, gypsum and plaster boards: apply one priming coat of MARMUR Fine, mixed 1:1 with IsoSil (siloxane clear sealer) and 4/5 parts of clean water. After 4-6 hours apply MARMUR FINE in two coats. </li>
  <li> Pre-existing chalking lime plasters: remove damaged and peeling  areas with an adequate tool or high-pressure washing; apply one priming coat consisting of  MARMUR Fine mixed 1:1 with IsoSil (siloxane clear sealer) and 4-5 parts of clean water. After a few hours smooth the wall with one coat of MARMUR Medium, if necessary. Wait at least 4-6 hours prior to the application of MARMUR lime coating. </li>
  <li> Old synthetic paints and plasters: remove the synthetic finishing coat with a paint remover containing no paraffin.. Wash the substrate by means of a high-pressure washing and prepare it according to its nature and following the instructions above. </li>
</ol>
<h2>Recommendation and Application Procedure</h2>
<p> MARMUR lime plaster is ready for use  and therefore does not require any water dilution. Apply in two coats with a stainless steel trowel  It is recommended to wait  8 hours between the 2 coats. Work into the second coat, while it is still setting, with a sponge float. The "marbling effect" typical of MARMUR Fine is achieved by polishing the second final coat with an inox trowel like, which must be kept wet with water and passed over the substrate until the required level of sheen has been reached.  Stain effects, patinas or transparent glazes maybe achieved  with Antiche Patine mixed with Lattedicalce and applied over MARMUR  with any tool, at least 12 hours after the second coat. </p>
<p> Do not apply with rainy weather or with air or substrate temperature below 5&deg;C. </p>
<p> Protect the facades from rain, at least along the first 48 hours, i.e. until lime has finished to set and started to get hard. </p>
<h2>Yield</h2>
<ul>
  <li>MARMUR Fine: 1,5-2kg/mq in two coats, depending on the roughness of the substrate</li>
  <li>MARMUR Medium: 1,8-2,5kg/mq in two coats, depending on the roughness of the substrate</li>
  <li>MARMORINO KS: 1- 1,2kg/mq in two coats</li>
</ul>
<p> Now, if you wish to end up with a very smooth finish, type Marmorino ks or Era Veneziana (we do quite a lot of Era Veneziana outside, specially in the region close to Venice), I would recommend as follows: </p>
<h2> On top of Cement rendering: </h2>
<ol>
  <li>ISOSIL + MARMUR FINE + WATER (first priming coat - brush applied)</li>
  <li>MARMUR FINE - one coat</li>
  <li>MARMORINO KS - one or two coats</li>
  <li>ERA VENEZIANA or ERA A PENNELLO (in case a glossy or semi-glossy finish is required)</li>
  <li>If required, top protection with ACQUADIVETRO, siloxane clear protection, brush applied and diluted with 20-30% of water. The siloxane resin allows for high permeability and makes the finish water-repellent at the same time</li>
