Product Information

Full details

The F Ball Stopgap P141 is an essential high-performance acrylic primer designed for professional flooring installers and DIYers preparing non-absorbent subfloors for levelling compounds. Its primary benefit is the creation of a high-grip, textured surface that significantly enhances the mechanical bond between the subfloor and the smoothing compound, though users should be aware it requires a proper drying period of 1-2 hours before the next step can begin.

FAQs

Can P141 be used on porous concrete?

P141 is specifically designed for non-absorbent surfaces; for porous concrete, a more standard primer may be more appropriate.

Do I need to dilute the primer?

No, Stopgap P141 should be used neat, directly from the container.

Is it compatible with all smoothing compounds?

It is specifically recommended for use with Stopgap levelling compounds, particularly Stopgap 600.

Can I walk on the floor while the primer is drying?

It is best to avoid foot traffic on the primed area until it has completely dried to prevent contamination.

What is the best way to apply it?

Use a medium-pile roller for large flat areas and a brush to cut in around walls and obstacles.

What should I do if the primer freezes?

The product should be stored in a cool, dry place above 5 degrees Celsius to prevent damage.

Troubleshooting

Primer feels tacky after 2 hours

High humidity or low temperatures may slow the drying process; allow additional time and ensure adequate airflow.

Uneven texture after drying

Ensure the product is stirred thoroughly before application to keep the uPVC particles suspended evenly.

Difficulty in cleaning tools

Wash brushes and rollers immediately with warm soapy water before the acrylic binder sets.

Pros and Cons

Pros

  • Excellent adhesion on difficult non-absorbent surfaces
  • Bright yellow pigment makes it easy to see where it has been applied
  • Dries relatively quickly within 1-2 hours
  • Compatible with underfloor heating systems

Cons

  • Requires careful application to ensure uniform coverage
  • Not suitable for porous surfaces that require standard primers
  • Can be messy if spilled due to intense yellow pigment

Setup, Compatibility & Care

Before starting, ensure the substrate is structurally sound, clean, and dry. Stir the product well before application to ensure the uPVC particles are evenly distributed throughout the solution. Apply with a brush or roller in a thin, even coat. Avoid leaving puddles of primer, as excess material can hinder the drying process. Once dry, the floor should be protected from heavy traffic until the smoothing compound is applied. Clean all brushes and rollers with water immediately after use, as the product is designed to resist water once fully cured.
