Prevents discolouration when laying the following using the thick-bed process:
- Natural stone (paving slabs and sheeting)
- Stairs
- Cotto tiles
- Natural dimension stone
- Concrete dimension stones (e.g. Terrazzo)
- Ceramic tile and slab coverings
For laying on heating screed
Caution:
- Not suitable for transparent natural stones or those with a tendency to discolour
- Lay only on cement-based substrates
- In a clean container, mix Würth dry mortar with clean tap water for approx. 3 minutes until there are no lumps
- It is recommended to use a 600 rpm stirrer with a spiral or double disc stirrer
- First use a contact slurry to completely cover the pre-wetted substrate
- Apply the laying mortar to the contact slurry using the "wet on wet" technique until it reaches the required height
- A contact layer is to be applied across the entire reverse side of the material to be laid (natural stone, ceramic tiles, slabs and similar materials). The material is then also to be laid "wet on wet" into the desired thick bed, tapped flush and aligned
- The tile or slab should always be laid into a complete bed of mortar (cavities may lead to damage)
- Scrape out and clean the joints thoroughly before the mortar bed cures
- Apply in accordance with DIN 18 157, part 1
- Observe ATV DIN 18352
- Apply only as much mortar as is needed for the number of ceramic tiles and slabs etc. that can be laid into the fresh mortar bed within the working/open time
- Do not stir additional water into mortar that is firming up
