📋 Work instructions

ETICS inventory check:

Check existing wall insulation before starting – do not apply double ETICS!
• ETICS present and intact: Only remove plaster/paint, leave existing insulation in place, new reinforcement + top coat
• ETICS defective or not present: Completely rebuild (steps 0–9)

Plaster adhesion test:

Systematically tap the entire façade. Mark and remove any areas that sound hollow. Cut open cracks >0.3 mm and fill with repair mortar. Plaster must adhere to the entire surface before EPS is bonded.

EPS panel installation:

• Lay the boards in a pattern (staggered like brickwork), never cross joints
• Bonding area min. 40% of the panel back (edge bead + blobs)
• Only insert COMBI FIX PLUS plate dowels after the adhesive has hardened (min. 24 hours)
• At building corners: corner boards in a staggered pattern

Window and door openings:

• APU strips for a tight connection to all window frames
• Diagonal reinforcement at all window corners (20×40 cm pieces of fabric at a 45° angle under the main fabric)
• Never allow ETICS to meet at window corners – always cut out in an L-shape

Glass façade recess:

ETICS is recessed on balconies with glass facades. Finish the edge neatly with an aluminium end profile, connecting joint with permanently elastic sealant (Sikaflex-11 FC+).

⚠️ Killer questions:

1. Bead point method (AL 88) meticulously executed? The adhesive edge must be closed all around – this prevents underflow and panel movement.
2. Are the dowels long enough? For 80 mm EPS + adhesive + old plaster: min. 135–155 mm length.
3. APU strips installed on all windows? Direct plaster connection to the frame immediately leads to cracks in Portugal due to UV expansion.
4. Diagonal reinforcement installed at window corners? Additional 20×40 cm fabric at a 45° angle under the main reinforcement is mandatory.
5. Fabric (FASSANET 160) in the outer third? Must not lie directly on EPS, must be embedded in FK 626.
6. EPS graphite protected from the sun? Grey panels warp/bend extremely quickly when exposed to direct heat unless reinforced.
7. Is the adhesive layer on the wall head correct? The waterproofing of the wall head must overlap the facade insulation at the top – strictly from top to bottom down to the gutter.

⚠️ Observe drying times:

• After bitumen sealing of balconies: wait at least 3 months before applying ETICS to balcony walls
• Measure wall moisture: equilibrium moisture below 3–5%
• Do not apply in rain, frost or direct sunlight

📋 Work instructions

Joint strategy for lengths of 10+ metres:

1. Normal joints: ARJUNT UNIVERSAL with a minimum width of 4–5 mm. Narrow joints crack immediately in heat.
2. Expansion joints (field boundaries): One approx. 10 mm wide joint every 3–4 m. Do not fill with joint mortar, but completely with Sikaflex-11 FC+. This joint must be congruent through tiles and mortar bed to the dimpled membrane.

Expansion joints must be congruent:

The elastic joint (Sikaflex) must run through the entire structure – exactly where the Rivnet rails have their 5 mm spacing. Joint in tile, mortar bed and drainage mortar exactly on top of each other.

Bitumen installation:

• Lay all bitumen layers strictly from top (ridge) to bottom (gutter).
• Corners: Extend strips 15–20 cm around the corner to the adjacent side, overlapping the second strip on top. Place a separate corner strip (30 cm wide) under the surface strips for reinforcement
• Over diagonal butt joints: stick a 30 cm wide strip of ESTERDAN 30 P ELITE SELF-ADHESIVE
• Allow the primer on the cement screed to dry completely – solvent residues prevent permanent adhesion of the ESTERDAN strips

DANODREN H15 PLUS – fleece overlap:

Overlap the fleece without gaps. As soon as cement residue from the ARGACAD runs into the studs, a rigid connection is created and the decoupling is lost.

Wall connections (windows):

Use Sikaflex-11 FC+ as an elastic seal to the wall/frame – never use hard joint mortar. Allow sufficient clearance for thermal movement.

📋 Work instructions

Substrate sequence:

1. Complete surface strip-back – tiles, adhesive, old screed down to raw concrete
2. Check concrete – fill cracks with Sika MonoTop-4100, chisel off loose areas
3. Levelling the surface – even out unevenness >5 mm
4. Dry? – Residual moisture <4% (CM measurement) before bitumen

Expansion joints:

1. Seal edge joints all around 10 mm with PE round cord + Sikaflex-11 FC+
2. Never fill expansion joints with joint mortar – only permanently elastic (Sikaflex)
