Substrate Preparation This is the most crucial step The substrate must be clean dry sound and free from dust debris oil and other contaminants Any loose or deteriorated concrete should be removed Cracks should be properly cleaned and repaired before applying Ardex DS 70 Priming may be necessary depending on the substrate 2 Mixing Follow the manufacturers instructions meticulously regarding watertopowder ratio Use a lowspeed drill with a mixing paddle to ensure a smooth lumpfree consistency Avoid overmixing 3 Application Pour the mixed Ardex DS 70 onto the prepared surface and allow it to self level For larger areas consider using a spiked roller to help distribute the material evenly and remove air bubbles For thinner applications a squeegee might be more appropriate 4 Drying and Curing Allow the Ardex DS 70 to dry according to the manufacturers recommendations Proper curing is essential for optimal strength development This often involves maintaining appropriate temperature and humidity levels 5 Finishing Touches Once dry any minor imperfections can be sanded smooth Always refer to the Ardex DS 70 technical data sheet for specific curing times and recommendations based on thickness and environmental conditions Troubleshooting Common Issues Even with careful application challenges might arise Here are some common problems and their solutions Cracking Cracking can result from insufficient substrate preparation improper mixing or rapid drying Ensure proper substrate preparation and follow mixing instructions precisely Pinholing Small holes can appear due to trapped air Use a spiked roller to release air bubbles during application Uneven Surface Inadequate leveling or insufficient drying can lead to uneven surfaces Use a level to monitor application and ensure proper drying time 3 Poor Adhesion Poor adhesion is usually due to a dirty or poorly prepared substrate Thoroughly clean and prime the surface before application Beyond the Basics Advanced Applications and Considerations Ardex DS 70s versatility extends beyond basic concrete repair Consider these advanced applications Underlayment for Tile Installations Its smooth level surface provides an ideal substrate for tile installations ensuring a longlasting beautiful finish Creating Slopes for Drainage Its selfleveling capabilities allow for the creation of controlled slopes for improved
