Question 1

What is Mapeflex PU 45 FT and what is it used for?

Accepted Answer

Mapeflex PU 45 FT is a one component elastomeric polyurethane sealant designed for interior joints and bonding. It provides a flexible, paintable seal that adheres to most common building substrates, accommodates movement, and can be painted over with conventional paints without priming.

Question 2

What are the key properties of Mapeflex PU 45 FT?

Accepted Answer

Key properties include: one-component polyurethane formulation, high elasticity, strong adhesion to typical building substrates, paintability without primer, ease of application and tooling, and long-term durability suitable for indoor use such as kitchens and bathrooms.

Question 3

Can Mapeflex PU 45 FT be painted over, and on which substrates does it bond well?

Accepted Answer

Yes, Mapeflex PU 45 FT is paintable with standard interior paints without needing a primer. It bonds well to concrete, brick, plaster, metal, wood and other common building surfaces typically found indoors.

Question 4

How do I apply Mapeflex PU 45 FT correctly?

Accepted Answer

Prepare the joint by cleaning and drying the surfaces. Cut the nozzle and load the cartridge into a standard caulking gun. Apply the bead evenly, then tool it to a smooth finish and remove excess material. Clean up with soap and water before it cures; no primer is normally required on suitable substrates.

Question 5

How long does Mapeflex PU 45 FT take to cure and what affects curing time?

Accepted Answer

Curing is influenced by ambient temperature and humidity. It develops more quickly in warm, humid conditions and will continue to cure over time, maintaining elasticity as the joint moves. Deeper joints may take longer to fully cure.

Question 6

Is Mapeflex PU 45 FT suitable for use in bathrooms and kitchens?

Accepted Answer

Yes. Mapeflex PU 45 FT is described as a long-life, flexible sealant suitable for interior areas such as kitchens and bathrooms where joints experience movement and exposure to moisture.

Question 7

Should Mapeflex PU 45 FT be used outdoors or only indoors?

Accepted Answer

Mapeflex PU 45 FT is designed for indoor use. Exterior exposure and immersion may require a different product formulation with appropriate weather resistance.

Question 8

What surface preparation and joint guidelines should I follow before applying Mapeflex PU 45 FT?

Accepted Answer

Ensure surfaces are clean, dry and free of dust or contaminants. For deep joints, use a backer rod to control depth and avoid bottom-sag. While primer is not required on many substrates, always follow the product SDS for specific surfaces and watch for any substrate-specific recommendations.

Question 9

What safety and handling practices should I follow when using Mapeflex PU 45 FT?

Accepted Answer

Use in a well-ventilated area. Wear appropriate protection such as gloves and eye protection. Avoid skin contact and wash thoroughly with soap and water if exposed. Follow the safety data sheet (SDS) for detailed handling, storage and disposal guidance.

Question 10

How should I remove or replace Mapeflex PU 45 FT if I need to redo a joint?

Accepted Answer

Cured Mapeflex PU 45 FT can be removed mechanically by cutting or scraping. For reapplication, clean the joint area and ensure it is dry before applying a new bead. Use manufacturer guidance from the SDS for removal solvents if needed.

Question 11

What is the value proposition of Mapeflex PU 45 FT compared with typical alternatives?

Accepted Answer

Mapeflex PU 45 FT offers a combination of high elasticity, strong adhesion, paintability without priming, and long service life, which can translate into fewer re-seals and easier maintenance compared with non-paintable or less flexible sealants.

Question 12

How does Mapeflex PU 45 FT compare to Mapeflex PS Sl B 0.22L in terms of use and packaging?

Accepted Answer

Mapeflex PU 45 FT is a polyurethane sealant designed for interior joints with high elasticity and paintability, typically in a standard cartridge. Mapeflex PS Sl B 0.22L is a smaller packaging option that may be suitable for shorter or smaller interior sealing tasks.
