If you are laying new tiles or slabs as part of a renovation project, you may often be surprised by difficult substrates that are unexpectedly exposed. If you are dealing with cracked screed, mixed substrates, gaps in flooring or old wooden flooring, it is not always necessary to completely remove the old screed or substrate in order to establish a firm substrate ready for tiling.
Depending on the individual substrate, a special PCI system solution comprising glass fiber reinforcement and fiber-reinforced leveling compound provides a friction-locked bond to the old substrate.
The best cards for any challenge:
CRACKED SCREED
1. Substrate: Critical substrate, e.g. cracked screed
SUBSTRATE PREPARATION
2. Primer: PCI Gisogrund 404 – Wash primer for absorbent and non-absorbent substrates, apply two coats
3. Reinforcement: PCI Armiermatte GFM – Reinforcing fiberglass mesh for installation in PCI floor levelers
LEVELING
4. Leveling: PCI Periplan Extra – Leveling compound for critical substrates under top coverings
LAYING
5. Laying: PCI Flexmörtel S1 Flott – Flexible flowable adhesive, especially for large-format floor tiles PCI FT Extra – Polymer-modified tile adhesive for all ceramic tiles
GROUTING
6. Grouting: PCI Nanofug Premium – Multi-use, flexible joint grout for all tiles and natural stones
5. Laying with PCI Flexmörtel S1 Flott or PCI FT Extra
6. Grouting with PCI Nanofug Premium
7. Installing elastic joints with PCI Silcofug E
One system – many benefits:
■ No need for time-consuming friction-locked sealing of cracks with reaction resins or removal of old screed ■ Low height, from 5 mm ■ Maximum safety on critical substrates with multi-directional fibers and strong reinforcement ■ Easy use – rapid progress
WOODEN FLOORING
SUBSTRATE PREPARATION
1. Substrate/substrate preparation: Firm, stable wooden substrate PCI Adaptol – Acrylic joint sealant for sealing joints between boards or alternatively application of non-sag fairing coat PCI STL 39 and PCI Gisogrund 404(diluted 1:1) as make-up fluid for sealing joints
2. Priming: PCI Gisogrund 404 – Wash primer for absorbent and non-absorbent substrates
3. Reinforcement: PCI Armiermatte GFM – Reinforcing fiberglass mesh for installation in PCI floor levelers
LEVELING
4. Leveling: PCI Periplan Extra – Leveling compound for critical substrates under top coverings
LAYING
5. Laying: PCI Flexmörtel S1 Flott – Flexible flowable adhesive, especially for large-format floor tiles PCI FT Extra – Polymer-modified tile adhesive for all ceramic tiles
GROUTING
6. Grouting: PCI Nanofug Premium – Multi-use, flexible joint grout for all tiles and natural stones
7. Joint sealing: PCI Silcofug E– Elastic silicone sealant, for indoor and outdoor use
1. Sealing board joints with PCI Adaptol or priming coat of PCI STL 39+ PCI Gisogrund 404
2. Priming with PCI Gisogrund 404
3. Reinforcement with PCI Armiermatte GFM
4. Leveling with PCI Periplan Extra
5. Laying with PCI Flexmörtel S1 Flott or PCI FT Extra
6. Grouting with PCI Nanofug Premium
7. Installing elastic joints with PCI Silcofug E
One system – many benefits:
■ Maximum safety on critical substrates with optimum bonding and elasticity ■ Low height: ideal for renovation ■ Easy, reliable solution for non-rigid substrates combined with rigid coverings
OLD TILING
1. Substrate: Firm, stable old tiling
SUBSTRATE PREPARATION
2. Primer: PCI Gisogrund 404 – Wash primer for absorbent and non-absorbent substrates
LEVELING
3. Leveling: PCI Periplan Flow – Leveling compound for use under all top coverings
LAYING
4. Laying: PCI Flexmörtel S1 Flott – Flexible flowable adhesive, especially for large-format floor tiles PCI FT Extra – Polymer-modified tile adhesive for all ceramic tiles
GROUTING
5. Grouting: PCI Nanofug Premium – Multi-use, flexible joint grout for all tiles and natural stones
6. Joint sealing: PCI Silcofug E– Elastic silicone sealant, for indoor and outdoor use
2. Priming with PCI Gisogrund 404
3. Leveling with PCI Periplan Flow
4. Laying with PCI Flexmörtel S1 Flott or PCI FT Extra
5. Grouting with PCI Nanofug Premium
6. Installing elastic joints with PCI Silcofug E
One system – many benefits:
■ Cost and time savings as old tiling does not need to be removed ■ Short interruptions to use – less dust, dirt and noise ■ Low height: ideal for renovation ■ No leveling of joints – level substrate is created in one step through leveling
