Fenestra Old World Finish
Description:

Fenestra is a traditional gypsum-lime plaster designed to provide color and depth for interior surfaces.  Fenestra is applied over a sealed and bonded gypsum surface. Fenestra may also be applied up to 3/8” in a single pass and be used for repair and restoration of traditional or veneer plasters.  Colors and visual effects are created by broadcasting Fenestra mixed with accent color(s) on the surface of the colored wet plaster and by the types and methods of troweling.  

Packaging:
Fenestra is packaged in recycled bags or pails
35lb /15.8 kg bag

Substrates:
Fenestra may be applied over sealed, bonded, gypsum hard wall plasters or gypsum wallboards.

Coverage:
Two coats of Fenestra will cover approximately 90 square feet per 35# bag
Applications and Tools:
**ALL TROWELS USED FOR APPLICATION AND POLISHING OF INTERIOR PLASTERS MUST BE WELL-BROKEN IN OR SCRATCHES AND IMPERFECTIONS WILL APPEAR ON THE FINISHED SURFACE.

Substrate and Surface Preparation:

Gypsum wallboards must be brought to a level 3-surface.  Blackcap Concentrate is sprayed or rolled over the surface and must dry for a minimum of 30 minutes.  (Cool temperatures and high humidity may prolong drying period.)

Larsen Product Corp, Plaster Weld is applied over the 'Blackcap' after Blackcap has dried. Before applying Blackcap or Plaster Weld type bonder, assure the surfaces are free of dust, dirt or other contaminates that may affect sealing and adhesion.

Mixing:
Pour 2 gallons of potable water (avoid warm water – it will accelerate set time.) into a clean 5-gallon pail.  Pour part of the bag of Fenestra into the water and the color pack for the base color - and begin mixing with a Windlock type paddle mixer.
Add the additional Fenestra from the bag to the water and continue mixing. After the entire contents of the 35# bag of Fenestra has been added – continue to mix an additional 1 to 2 minutes.

Plaster Application:
Apply Fenestra with a hawk and trowel.  Apply first coat at a 1/16” to 1/8” providing a level surface for the second coat.  Second coat is applied over the first coat at approximately 1/8”.  To apply the second coat the water droplets and wet sheen must be off the first coat.  The first coat however must be damp and cool to the touch.
Sufficient manpower must be available to bring plaster both vertically and horizontally to natural breaks avoiding cold joints. The second coat is applied uniformly over the surface - but at this point all trowel lines and imperfections do need to be troweled out.

Broadcast Color:
To achieve subtle variegated effects or contrasting highlights, wet Fenestra mixed with the selected accent color(s) is broadcast by brush or trowel onto the wet surface of the second coat.

Due to the unique color process for Fenestra, a jobsite colored sample is highly recommended.

Determining Finish Styles (methods of ornamental troweling)
After the last color has been broadcast the pattern of the final troweling will determine the finish style or appearance.   There are 3 basic styles of Fenestra.  Using the trowel in various ways – unlimited styles are possible.

Finish Styles:
Random Style 
To achieve the random style a 9” finish plaster trowel is recommended. Other size trowels may be used. Troweling randomly across the surface with differing pressure will add lines and character to the finished surface.

Ragged Style 
To the Random Style take a clean, dampened cotton cloth – bunch the cloth into the palm of your hand and randomly make shallow indentations in the wet plaster after the surface has been troweled.

Polishing
Second coat of Fenestra is ready for polishing when the sheen is reduced and no color remains on the fingertips after lightly touching the surface of the colored plaster.  (If color or plaster material is building up on trowel surface stop polishing immediately – and wait additional time until surface is ready.)  Hard Trowel (Item 2) the plaster surface until achieving a polished 'glass' finish

Wax Application
Rialto Wax is recommended to use with Fenestra.  Do not wax Fenestra until 24 hours after polishing second coat. A Pavan type trowel or a clean 100% cotton cloth (white recommended) may be used to apply wax coatings to Fenestra.  After a tight coat of wax has been applied to the surface and allowed to dry thoroughly – polish wax with an orbital buffer.

Fenestra Stain Application
Apply Fenestra Pre-Stain over the surface by pouring liquid into a clean pail and using a sponge to apply to the surface. Avoid drips and runs.  Allow the Pre-Stain to dry for 15 to 20 minutes. Pour Tinted Fenestra Stain into a clean pail (same pail the Pre-Stain was in.) Use a clean sponge to apply Fenestra Stain over the surface and into any surface features created from 'ragging' the surface.

Drying:
Gypsum plasters require stable temperatures and ventilation during application and during the period of time required for the plaster to dry. The required temperature range for the application and drying of gypsum plaster shall be 55°F to 80°F

Storage:
Fenestra shall be kept indoors or if stored outdoors, shall be adequately covered to keep dry and be stored off the ground.
