Substrate Preparation

Masonry, concrete or sound existing coatings must be clean, dry, adherent, sound, solid, dry, free from all substances, that may prevent good adhesion (e.g. formwork oil) and moderately water absorbent for a good adhesion. Remove mortar burrs and all unsound, flaking existing paints or textured plasters. Chip off all plaster areas showing cavities (local separation) and repair to match the surrounding surface. Clean highly absorbent, sanding or chalking surfaces thoroughly up to the solid substrate level and prime with concentrate Sylitol-Konzentrat 111. Cover attachment parts and window sills by tarpaulins and tape.

Preparation of Material

Capatect X-TRA 300 can be processed manually by a slow electric mixer or with all common plastering machines. For the manual processing pour the powder bag (25 kg) into appox. 9 to 10 l of tap water and stir up carefully to a lump free mass. Allow to swell for approx. 2 minutes and stir up again. If necessary, the consistency should be adjusted with a little amount of tap water after this ripening time.
Do not slurry up stiff mortar with water.

Consumption

for bonding of insulation boards:
approx. 4.0 - 5.0 kg/m2

as reinforcement layer:
approx. 1.3 kg/m2 per mm thickness; i.e. approx. 5.2 kg/m2 for a layer thickness of 4 mm

Guide value without correction for spill, loss and project specific conditions on site. To be established by trials on site.

Application Conditions

Processing temperature: +5 °C to +30 °C for substrate, mortar and ambient air during application and curing. Do not apply on sun heated substrates (direct sunlight), during strong wind, fog, rain, high relative humidity or imminent rain and frost.

Drying/Drying Time

Surface-dry after 24 hours at 20 °C and 65 % RH. Curing time per mm of coat thickness: 1 day. Capatect X-TRA 300 dries by hydration and physically by evaporation of water. Lower temperatures and higher RH extend the drying process.

Tool Cleaning

Immediately after use with water.

Example for Machine Equipment

Capatect X-TRA 300 can be processed with nearly all common plaster machines, for example:
1) Flowmixer InoMIX F 21 
in combination with Inotec conveying pump InoBEAM F 21 (400 V)
2) Flowmixer M-Tec D 10 
equipped with standard dosing or mixing helix in combination with
    
conveying pump M-Tec P 25 (400 V) with conveying helix (1/1 output)
3) Mixing pumps like InoCOMB M4G, PUTZKNECHT S48.3 or PFT G4 (1/2 output)
Follow the instructions of the machine manufacturer strictly!

General basic information:

Electricity supply for flowmixer and conveyor:
 400 V rotary current /32 A (16A for mixer only) via site distribution with RCCB circuit breaker
Water supply:
3/4" hose; minimum pressure 2.5 bar ; approx. 330 litres/hour. The desired fresh mortar consistency can be set by the fine-regulating valve in the water-fitting of the mixer.
Hose pipe: First hoses (max. 3 units) - interior Ø 35 mm, 13.3 m each, end hose - interior Ø 25 mm, 10.0 m; total max. range approx 50 m. Lower values depending on temperature and building conditions
Spraying unit: Nozzle size Ø 8 to 12 mm

Basic notes:
Rinse hoses with lime laitance or wall paper glue before processing the mortar.
When work is interrupted, do not leave the hose in direct sunlight and protect open mortar pail with plastic foil and keep gun and nozzle under water.
Do not extend processing breaks longer than 30 minutes to avoid stiffness of the fresh mortar inside the hoses and congestion in mortar flow.
When processing with an open combination of flow mixer and mortar pump: Empty the material reservoir as good as possible to avoid tunneling when restarting. If this is not respected, the material may need to be removed before restarting the machine (switched off) and made it run.
For more information, see "Manual for Spraying Technology".

Installation

Cover the scaffoldings with tarpaulins to protect the surface from rain during the drying phase, if necessary. Follow national or local regulations and specifications for applying mineral based mortars. In Germany: Follow  DIN 18550-1.

Remove any existing offsets from the polystyrene board surface and remove any adhering abrasive dust.

Application

Fixing of Insulation boards:

Part-surface bonding technique: Apply freshly prepared mortar of Capatect X-TRA 300 thoroughly to the reverse side of the thermal insulating board, by using the "Bulb-Point-Method":
A bulb of mortar, approx. 5 cm wide, surrounds the board and 3 blobs (palm of the hand sized) are to be applied in the middle of the board. Adjust the thickness of applied material (base height) to the tolerances of the substrate, such that ≥ 40% surface area is in contact with adhesive. Note: Prime bulb-point areas on mineral wool boards first with a grout coat of this mortar for better adhesion.

Full-surface bonding technique (only on flat surfaces and suitable insulation panels): Spray the adhesive mortar on the substrate by machine up to approx. 8 mm thick. Immediately before the insulation boards are placed, comb the adhesive mortar with the square-notched  trowel (the notch width and depth depends on the condition of the substrate). Immediately place the insulation boards into the fresh adhesive mortar bed, flush and press in. In order to avoid skin formation, only the amount of adhesive is to apply, that can be covered directly. Press the boards staggert into the mortar bed firmly from the bottom to the top. Do not put any adhesive mortar into the board joints.

Bonding within rail mounting: Apply blobs of mortar on the reverse side of insulation board (> 20 % of the board surface) and stick board into the horizontal profile. For further processing see application manual.

To avoid skin forming apply only mortar on areas which can be covered immediately with insulation boards. Pay attention to alignment and verticality. 

Reinforcemment layer:
Sand offsets in the EPS board joints and remove adherent dust.
In the case of mineral wool or hemp insulation boards: Before applying the reinforcement layer, smooth and level the insulation board surface.
Protect all corners and reveals of windows with edge guard profiles. Apply diagonal reinforcing fabric to the edges of openings and edge protection along window sides and building corners. Apply the adhesive mortar onto the thermal insulating boards in the width of a reinforcing fabric sheet. Press Capatect Gewebe 650 very thoroughly into the freshly applied, still wet reinforcement layer with an overlap of approx. 10 cm. Apply a subsequent layer of Capatect X-TRA 300 (wet-in-wet), to guarantee the complete embedding of fabrics. Embed the fabric centrally at reinforcement layer thicknesses up to 4mm and embed it in the outer half of the reinforcement for thicknesses > 4mm. Provide a minimum reinforcement layer thickness of 3mm for EPS and 4mm for mineral wool.

building corners and edges:
When using the Capatect Eckschutzschiene 655, place the Capatect Gewebe 650 about 10 cm overlapping the edge. When using Capatect Gewebe-Eckschutz 656 or 657, the fabric stripes are leading right to the edge.

 

Render layer:
Depending on weather conditions, the water absorbency and the used finishing render, the reinforcement may need to be primed with Putzgrund 610 before applying the textured finishing render.
