Craftsman Guide / Preparation & Substrates
Application: Vinyl Sheet
Practical guide for preparation, leveling transitions, and priming on vinyl sheeting in wet rooms.
🛑 Before You Start — Inspect the Vinyl Sheet:
• No Bubbles or Delamination: Inspect the entire vinyl membrane thoroughly. The sheet must be fully adhered and not lifting at corners or along wall upstands.
• Critical Around Floor Drains: Ensure the sheet has not delaminated or compromised its bond around the floor drain. Any void or deflection under the membrane will cause the microcement to crack over time.
• Sample Board: Always produce a sample of at least 60×60 cm in the correct color and texture for client approval.

💡 Tips for Corners and Finish on Vinyl Sheeting:
• Vinyl sheets often have overlaps and coved corners, making it harder to obtain angles as crisp as those on plasterboard or tiles.
• Vinyl on Both Wall and Floor: Naturally results in rounded transitions. For sharper definition, tape and slice internal corners straight on the final coat.
• Tile on Wall and Vinyl on Floor: Leveling the step at the vinyl upstand automatically straightens and squares the corner.

1. Leveling Transitions & Floor Drains
2. Priming Vinyl Sheet
Floor: Forprime DPM
2-component epoxy primer for non-porous floor membranes.
• Application: Roll Forprime DPM evenly across the entire vinyl floor.
• Sand Blinding: Always blind to saturation with quartz sand if the next coat is Microbase XT. Prior to Forprime HB/FL, sand blinding is only necessary if the coat is not applied within 24 hours.
• Drying Time: Allow to cure for at least 6–8 hours before walking on the surface.

Wall: Monogrip
Grip primer with quartz texture for vertical surfaces.
• Application: Roll a thin, even coat of Monogrip over the wall vinyl.
• System Selection: Standard primer prior to build-up with Monostone XL and reinforcement mesh.
• Drying Time: Allow to dry for approximately 30–60 minutes to a rough, non-tacky surface before skim-coating.

⏳ Drying Times & Ventilation: Ensure repair mortars and primers are completely dry before applying base coats. Maintain good ventilation in the workspace with open doors and circulating fans.
