Foam sealant Fischer DMA 310ml White

Fischer DMA 310ml White is a universal polyurethane foam sealant designed for sealing, filling and insulating gaps and joints. Supplied in a 310 ml can, the white foam adheres to a wide range of common building materials and cures to form a durable, insulating seal that reduces air infiltration and improves thermal and acoustic performance. The product is suitable for both interior and exterior applications when protected from direct UV exposure and when used in accordance with standard building practices.

Advantages

The foam delivers good adhesion to materials such as concrete, brick, wood, metal and many plastics, and expands to fill irregular cavities and joints. Its insulating properties help to reduce heat loss and limit sound transmission. The 310 ml format offers a practical balance between application control and coverage for typical sealing tasks. The cured foam is dimensionally stable and provides long-term performance when properly installed and trimmed.

Suitable for

• Sealing gaps around window and door frames
• Filling cavities and pipe penetrations
• Thermal and acoustic insulation of wall and ceiling joints
• Filling voids in masonry and carpentry work

Key specifications

• Formulation: one-component polyurethane foam
• Color: white
• Volume: 310 ml
• Application temperature range: suitable for typical ambient and substrate temperatures (refer to label for limits)
• Paintability: can be trimmed and painted after full curing
• Adhesion: adheres to masonry, concrete, wood, metal and many plastics

How to use

Ensure surfaces are clean, load-bearing, free from dust, grease and loose material. Shake the can thoroughly before use and apply the foam from the bottom of the gap upwards, allowing for expansion. Use a compatible applicator or gun for controlled dispensing. After curing, excess foam can be cut away and the surface finished or painted as required. Follow safety and handling instructions on the product label, including adequate ventilation and protective gloves.

Usage recommendations

For best results, pre-moisten porous substrates slightly to improve adhesion and foaming behaviour. Apply in layers for deep cavities, allowing each layer to cure partially before adding more foam. Protect cured foam from direct sunlight and weather exposure or finish with an appropriate sealant or cladding when used externally.
