Flowcrete Flowtex F1 Repair Mortar 20Kg Kit

1. What is Flowtex F1 Mortar used for?

Flowtex F1 Mortar is a high-strength, three-component epoxy resin mortar used as a subfloor beneath resin flooring systems. It is suitable where a strong, thin-section screed is required and can be laid to falls or feathered to a minimum thickness of 1 mm.

2. How thick can Flowtex F1 Mortar be applied?

Flowtex F1 Mortar can be applied from 1 mm to 50 mm thickness in a single application. This makes it suitable for both thin repairs and deeper substrate correction before installing resin flooring systems.

3. How much Flowtex F1 Mortar is required per square metre?

The standard consumption is approximately 1.8 kg/m² for every 1 mm of thickness. For example, a 10 mm application would require approximately 18 kg/m², although actual consumption can vary depending on substrate conditions.

4. How strong is Flowtex F1 Mortar?

Flowtex F1 Mortar provides high mechanical performance, with a compressive strength greater than 55 N/mm², flexural strength above 20 N/mm² and tensile strength above 8 N/mm². It also offers excellent bond, impact and abrasion resistance.

5. How long does Flowtex F1 Mortar take to cure?

At 25°C, foot traffic is generally possible after approximately 18 hours, while vehicular traffic can resume after around 48 hours. Full chemical cure is achieved after approximately 7 days. The maximum overcoating time is 24 hours.

6. What substrate preparation is required before applying Flowtex F1 Mortar?

Concrete or screed should have a minimum strength of 25 N/mm² and be clean, sound and dry to 75% RH. Surface preparation should include enclosed light shot blasting or diamond grinding to a minimum CSP3 profile. Flowprime AU is specified as the primer.
