BOTAMENT® M 54 FM is a rapidly setting ready-to-use mortar on cement basis to produce composite screeds, screeds on separation layers and floating screeds.

• Ready to receive tiles after 24 hours
• Strongly hydrophobic (high protection against moisture penetration from the rear)
• For interior and exterior use
• Ready-to-use-mortar (no need for mixing with sand)
• Long working time
• Can be pumped

To produce the following types of cement screeds quickly ready to be covered:

• screeds on separating layers composite screeds
• screeds on insulation layers; heated screeds

• for use in wetrooms
• to repair and restore existing cement screeds
• to repair cement-based substrates prior to installation
• to set floor anchorings and fence posts

The substrate must be in the following condition:

• dry, clean and frost-free; stable
• free from grease, paint, cement laitance, separating agents, sinter layers and loose particles
• in true alignment and perpendicular

Composite screed:

• mix up bonding course with BOTAMENT^® D 10 screed admixture and water (at a ratio of 1:1)
• apply bonding course to the pre-wetted substrate by adding BOTAMENT^® M 54FM and brush in thoroughly

The installation of the screed is performed fresh on fresh onto the moist bonding course.

Screed on separation layer:

When installing screed onto a suitable separation layer no bonding course is required.

frost-free, cool and dry at least 9 months in its original sealed container

~ 1.5- 1.75 l water / 25 kg

Screeds made with BOTAMENT® M 54FM are ready to be covered after the following time intervals between installation and tiling or after the following maximal residual moisture contents (CM-measurement) have been reached:

unheated screed:

ceramic tiles and natural stones ≤ 2.00 %

elastic and textile coverings ≤ 2.00 %

wood flooring, laminate flooring and wood block ≤ 2.00 %

heated screed:

ceramic tiles and natural stones ≤ 2.00 %

elastic and textile coverings ≤ 1.80 %

wood flooring, laminate flooring and wood block ≤ 1.80 %

All specifications apply for composite screeds, screeds on separation layers and floating screeds.

~ 90 - 120 minutes

10 to 80 mm

after ~ 4- 6 hours

For the mixing of the screed mortar standard screed mixers or mixing and feed pumps are used. In the event of the working process being interrupted mixer, pumps and pipes must be thoroughly cleaned immediately.
