EP-Rapid Plinth / Repair Gel

Needs

Preparation and substrate check

Before EP-Rapid Plinth / Repair Gel is applied, it is necessary to make an inspection of the substrate.

The substrate must have a minimum compressive strength of 25 N/mm² and a minimum tensile strength of 2 N/mm².

The substrate must always be free of moisture and grease.
Use a moisture meter to measure the moisture percentage of the floor.
The moisture content in the substrate must be ≤ 5% moisture.
If it exceeds 5% to a maximum of 10%, you may choose to make the floor as dry as possible with a burner.
After treating the floor, 15 minutes after stopping the burning, a new measurement can be taken.

If the moisture percentage has not decreased, there may be an underlying moisture problem.
If this is the case, the underlying problem must be solved before applying EP-Rapid Plinth / Repair Gel.
Clean the floor with a degreaser and then with clean water before blasting or sanding.
This operation is best performed the evening before installation.

After degreasing, the substrate must always be mechanically pretreated.
This is preferably done by blasting the substrate.
If the installation conditions do not allow this, the substrate can also be sanded with a double ring diamond wheel.
The entire substrate must be sanded homogeneously.
Remnants of old coatings and adhesives must also be sanded away completely.
All substrates must first be made grease- and dust-free before sanding.

Points of interest by substrate

• Tiles: joints should be free of dirt, grease, other chemicals.
  Tiles should be sandblasted so that the ceramic or glaze layer is completely removed.
  Failure to completely sand tiles poses a risk of detachment.
  Loose or concave tiles should be removed.
• Chape: new chape must first cure for at least 28 days.
  It should not be sanded.
• Concrete: new concrete must cure for at least 28 days.
  Any protective top coat, impregnating agent or paint layer present on an existing concrete must first be sanded away.
  For polished concrete, it is very important to sand away the curing compounds on the surface.
  If the concrete is not polished, there may be a cement layer on the surface.
  This layer must also be sanded away.
• Anhydrite: degrease, then sand and dust.

Unevenness in substrate

In case unevenness of more than 5 mm are present in the substrate, they should first be smoothed out with EP-Rapid Plinth / Repair Gel gravel mixture.
Loose floor pieces or tiles should first be removed and then filled with EP-Rapid Plinth / Repair Gel gravel mixture.
Always saturate these areas with sufficient primer afterwards.

For repairing both uneven and loose areas, a mixture of EP-Rapid Primer (15-20%) and gravel 0.4/0.8 (85-80%) can also be chosen.
Refer to the technical data sheet of the relevant product.
After curing, sand the repaired areas with a double ring diamond wheel in order to obtain as flat a result as possible.
In case of cracks wider than 1 mm, these should first be ground in further and then filled with EP-Rapid Plinth / Repair gel.
After curing, sand the repaired areas with a double-ring diamond wheel.

Expansion joints in the substrate should also be followed when applying EP-Rapid Plinth / Repair Gel.

Conditions during placement

Recommended floor and ambient temperatures are between 10°C and 25°C with an ideal installation temperature of 18-22°C.

To shorten the drying time of baseboards in a yard with low floor temperature (<15°C), the room can be heated to 20-22°C the day before. Placement at lower temperature (down to 0°C) is possible, but the drying time will be considerably longer. The maximum air humidity is 80% RH. The temperature of the substrate and uncured products must be 3°C above the dew point. When installing below 10°C, it is very important to keep an eye on this parameter because there is a high probability of condensation forming at these low temperatures. Condensation on the surface must be avoided at all times.

Application as skirting paste

Processing

Dispense an amount of EP-Rapid Plinth / Repair Gel that can be processed within a 15-minute time frame.
Mix up one set of EP-Rapid Plinth / Repair Gel and apply it with a brush or brush as a primer on the spot where the skirting will be.
Primer with a brush or brush also a distance of 5 cm on the floor in front of the baseboard.
• Then mix up a 2nd set of EP-Rapid Plinth / Repair Gel.
  Then add in 2 times total 9 kg of colored gravel 0.4/0.8.
  To do this, first put half of the gravel in a bucket, then add the plinth paste and mix through.
  Then add the rest of the gravel and mix well for 1 to 2 minutes to form a homogeneous paste.
• Apply the compact mortar to the wall with a trowel/plaster knife and then finish with a hollow or straight angle trowel to give the skirting board the correct shape.
  When doing so, always work wet-in-wet between 0 and 30 min after placing the primer coat.

Points of attention

• If EP-Rapid Plinth / Repair Gel is spilled on a plinth profile, remove it immediately.
  Clean the profile with a cloth soaked in Isopropanol.
  Do not use a brush as the solvent may come into contact with the skirting board.
  This may cause color differences and significantly increase the drying time of the baseboard.
• The joint between the skirting board profile and the wall must be sealed liquid-tight with sanitary sealant before the floor is installed.
  This will prevent water from entering through the wall under the skirting and/or floor.
• Both the trowel and the baseboard can be misted with water.
  This will make processing even smoother and give you a tighter and better compacted skirting.

Implementation of repairs

Smoothing out pits and unevennesses

• Prepare the substrate as described under section “Preparation and control of substrate”
• Primer the substrate.
  Please refer to the technical data sheet of the respective primer.
• Prepare the Rapid Plinth gravel mixture according to the skirting method.
• Apply the Rapid Plinth gravel mixture into the surface to be flattened.
  Use a trowel to do this so that there is a minimal height difference.
  Then press down firmly.
• Before priming the floor, first saturate the repair with primer.
• After the required drying time, sand the surface with a double-ring diamond wheel.
• Then the floor and the repaired surface can be primed.
  Refer to the technical data sheet of the relevant primer.

Filling of cracks

• Cracks wider than 1 mm should be ground in further first.
• Then mix up the A and B components according to the specified mixing ratio.
• Apply the mixture into the crack with a trowel or putty knife, making sure the crack is completely filled.
• After the required drying time, sand the surface with a double-ring diamond wheel.
• Then the floor and the repaired surface can be primed.
  Refer to the technical data sheet of the respective primer.

Cleaning

Clean the used tools with Cleaner EP, isopropanol or acetone. Cured product residues must be removed mechanically.

Storage and preservation

Shelf life: 12 months in a closed and original container when stored in a dry and cool place (10-25°C)
