Surface preperation
1. Surface patching (conditional)
Refer to substrate manufacturer's instructions for caulking gaps and filling imperfections.
Fillers and caulks must be finished flush or slightly below the regular surface of the substrate.
3. Surface priming (conditional)
Primer+ is intended for absorbent substrates (particularly if soiled or damaged). Unsoiled surfaces may not need priming. Refer to instructions on container.
Note Primer+ will reduce the ability to immediately reposition or remove SAU+ easily in years to come.
2. Surface cleaning
Scrape.
Broom.
Vacuum.
Mop (frequently change water).
Check fasteners are flush or below surface.
4. Setout
Check squareness of room and
commence chalk-line setout from a datum that suits the perimeter finish (optionally at wall on to Junction Tape+ or turned up wall without Junction Tape+).
Apply chalk-lines at 1305mm intervals at right-angles to the long axis of substrate.
Installation
5. Bondbreaker taping
(conditional)
Apply Bondbreaker Tape+ over joins to all high movement sheet systems, including:
Scyon Secura™
Innova Durafloor™
Cemintel Constructafloor™
YELLOWtongue™
MgO board.
Trade marks (denoted TM) are the property of their respective owners.
7. Junction taping
Cut Junction Tape+ to length and remove backing paper from floor side then apply full length tightly into the corner. Next remove backing from wall side and apply progressively.
Note installers can avoid use of Junction Tape+ if SAU+ is to be turned up the wall.
9. Joint base taping
[duplex joint]
Rollout Base Tape+ at each chalk line. Centre over chalk line and remove backing and stick down.
Note continue Base Tape+ up the wall 50mm to 60mm if SAU+ is to be turned up the wall (as opposed to being terminated at the wall on Junction Tape+).
11. Joint top mesh taping
[duplex joint]
Apply Top Mesh Tape+ to join.
Note Top Mesh Tape+ is self-adhesive and will stay in place during application of SMX50.
6. Junction caulking
Caulk wall junctions with Soudal SMX50.
Note the next step of applying Junction Tape+ should be undertaken while SMX50 is wet.
If Junction Tape+ is to be applied after SMX50 is dry (partially or fully) then trowel/tool SMX50 flush to avoid protrusions.
8. Corner taping
Bed-in SoudaTape IC (internal corner) or OC (external corner) using SMX50.
Ensure all the inside surface is generously coated with SMX50 and all air pockets are removed when IC/OC is pressed into place.
10. Laying
Lay SAU+ along chalk line and peel back a 200mm starter strip. Check alignment full length then stick down the starter strip only.
Peel backing from underneath progressively sticking down SAU+ with a float.
Do not overlap joins.
12. Joint bonding
[duplex joint]
Apply SMX50 to Top Mesh Tape+.
Note a short test run (including trowelling flat) will help determine the appropriate volume of SMX50 for good coverage.
13. Joint finishing
[duplex joint]
Trowel SMX50 flat and prime (overcoat) with Primer+ (wet-on-wet application is acceptable).
Note use masking tape on transitions to strip-drain flanges (remove masking ASAP after trowelling).
Notes
Hot-weather restrictions apply to exterior applications. Always apply on a hot day followed by a cold day. The opposite may result in some persistent bubbles.
Rollout SAU+ with coating facing up (avoid bending sharply backwards).
C2S1 ceramic tile adhesive (CTA) is recommended for general applications.
C2S2 CTA is recommended for crack-isolation applications.
CTA containing solvent (typically pre-mixed CTA) is not recommended due to the potential for solvent degradation.
Conduct industry standard testing and preparation prior to application.
