Sealant FISCHER DA 053111 — acrylic-based indoor sealing compound (MPN 053111)

FISCHER DA 053111 is an acrylic-based indoor sealant formulated for sealing and finishing joints, cracks and gaps on interior plaster, masonry and painted surfaces. The compound cures to a flexible, paintable finish that accommodates minor movement and provides a neat surface for subsequent decoration. It is supplied for application with a standard cartridge gun and is intended for renovation, finishing and routine household repair tasks where a general-purpose interior sealant is required.

Advantages

The acrylic composition offers good adhesion to common interior substrates such as plaster, brickwork and painted surfaces while remaining sandable and paintable after curing. The sealant provides controlled elasticity to absorb minor substrate movement and helps prevent visible cracks reappearing after repair. Application from a standard cartridge allows for precise bead control and reduced material waste. The formulation is suitable for indoor use, where resistance to moisture and moderate wear is required but no specialist chemical resistance is necessary.

Suitable for

• Sealing and finishing gaps between plasterboard and skirting or architrave
• Filling hairline cracks in interior plaster and masonry
• Joining painted surfaces prior to repainting
• General household repairs and renovation finishing work
• Interior areas where a paintable, sandable seal is required

Key specifications

• Type: acrylic-based indoor sealant
• Application method: standard cartridge gun
• Finish: flexible and paintable after curing
• Substrate compatibility: plaster, masonry, painted surfaces
• Curing: forms an elastic seal suitable for minor movement accommodation

How to use

Ensure surfaces are clean, dry and free of loose material, dust and grease before application. Cut the cartridge nozzle to the required bead size and apply with a standard cartridge gun, pressing the sealant firmly into the joint to ensure adhesion. Smooth the bead with a wet spatula or finger within the tooling time to obtain an even finish. Allow the sealant to cure fully according to ambient temperature and humidity; once cured, the surface can be sanded and painted with conventional interior paints.

Usage recommendations

Use at normal indoor temperatures and avoid applying in conditions of high humidity or below recommended ambient temperatures. For deep joints, backfill or use a suitable backing rod to control sealant depth and ensure adequate elasticity. Test paint compatibility on a small area if using solvent-based topcoats. Store cartridges upright in a cool, dry place and follow local disposal regulations for cured material and empty cartridges.
