Quantity

Cemtop GPF is indicated for use as a general purpose leveling layer for the preparation of floors prior to the application of tiles, carpets, vinyl, cementitious top layer, etc. As well as for diverse floors for areas of high traffic.

It can be used on finishing surfaces for pedestrian traffic and low traffic commercial areas; Is also suitable for the application of a layer of Nitoflor FC130 and subsequently of Nitoflor FC140.

Advantage

  • Glass fibers improve flexural strength and compression behavior.
  • Very fast application. Allows to apply large surfaces in one day.
  • Can be applied directly on concrete floors, eliminates the traditional plastering of sand and cement
  • Dimensionally stable. Allows placement in large areas
  • Fast acquisition of resistance and curing. It allows quick access to pedestrian traffic and to the placement of
  • Upper layers of carpets, tiles, etc., where appropriate
  • The one-component product eliminates the need for mixing on site and ensures the consistency of the blended product.

How to use

Surface Preparation

It is essential that both new and old concrete floors are properly prepared before applying Cemtop GPF.

Modified self-leveling cementitious layer with polymers and glass fibers

New concrete floors must be at least 21 days old. They must be dry, clean and free from wax, grease, oils, soil, mortar residue and paint or residue from the healer, foreign or loose material and grout.

Excess slurry should be removed by light blasting or thinning followed by washing and vacuuming to remove any traces of dust. Oil and grease stains can be removed with a chemical degreaser followed by a clean water rinse. In old concrete where there is deep seated contamination, mechanical methods such as sand blasting, grinding and roughing will be used to achieve a suitable clean surface.

If you need advice or more information regarding the preparation of the substrate, please contact Fosroc

Primer coat

The surface should be primed to prevent release of air from the substrate. Meticulously prepare the surface as described previously.

Prime the soil with Nitoprime 33 (volume ratio, primer: clean water, 1: 5) and let it dry.

Re-prime the soil with Nitoprime 33 (volume ratio, primer: clean water, 1: 3) and let it dry. Apply the required thickness of Cemtop GPF on the primed and dry surface.

Application

Although the product has been designed to be applied by a pump, it can also be applied manually.

Pumping Application

This is a specialized activity that must be performed by an applicator authorized by Fosroc, knowledgeable about the product, and using an appropriate equipment.

Manual application

Typically, in areas of less than 100 m², it will be more practical to apply Cemtop GPF manually.

Mixture

Mix 25 kg of Cemtop GPF with the required volume of clean water (see table "Estimation"). A typical batch would be 2 bags of 25 kg of the product.

Pour the water into a clean mixing bowl. Slowly add the powder to the water, mixing continuously with a low speed drill that has adjusted a mixing paddle. Mix at least 3 minutes until smooth and creamy. Make sure there are enough personnel to ensure uninterrupted mixing and pouring once the application has begun.

Apply Cemtop GPF within 2 minutes of the completion of the mix. Pour the mixed material onto the dry primed substrate, spread it with trowel and allow it to level. Pass a barbed roller across the surface to eliminate possible air entrained in the material and facilitate leveling. Do not over-work with the roller. To reduce joint formation, the newly mixed Cemtop GPF should be applied within 5 minutes after the previous product discharge.

Note: If the mixture hardens, it should be discarded; Do not attempt to re-mix with water.

Limitations

The surface of concrete slabs on which Cemtop GPF is to be applied must be at a minimum temperature of + 5 ° C and the ambient temperature must be equal to or greater than + 10 ° C during application. If the temperature is above 25 ° C during application, consult the Fosroc Technical Department. Protect from freezing for 48 hours.

To prevent rapid drying, protect it from direct sunlight and dry air during application and initial curing.

The possible movements or cracks of the substrate can be reflected on the surface of Cemtop GPF. Cemtop GPF should not be applied to asphalt substrates. Cemtop GPF is not suitable for application outdoors or on surfaces that can get wet.

performance

Cemtop GPF: 1.7 kg of powder per mm of thickness and m2 of surface.

Nitoprime 33:

5 m2 / liter of concentrate -> 2 coats of primer

4 m2 / liter of concentrate -> 3 coats of primer

3 m2 / liter of concentrate -> 4 coats of primer

Storage

Store indoors, in a cool, dry place and in original and closed containers. The product has a storage period of 6 months from the date of manufacture, if stored in a dry place and in original and closed containers. If stored at high temperatures and / or in high humidity conditions, the storage period may be reduced to less than 3 months.

Nitoprime 33 has a shelf life of 12 months at 20 ° C. Protect it from frost and extreme heat.

Precautions

Safety and hygiene

Cemtop products contain cements which, when mixed with water or moisten, give off alkalis which can be harmful to the skin. Avoid inhalation of dust. Avoid contact with skin and eyes. Wear gloves and goggles. In case of contact with skin, wash with water. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

Nitoprime 33 should not be allowed to come into contact with skin or eyes, or be ingested. Wear suitable gloves and eye / face protection. In case of contact with skin, wash thoroughly with soap and water. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If swallowed, seek medical advice immediately. Do not induce vomiting.

For more information consult the Material Safety Data Sheet.

Fire

Cemtop GPF and Nitoprime 33 are not flammable. The fire resistance of Cemtop GPF is classified as A1FL.


Additional Information

Joints

Expansion joints of the existing substrate should be continued in Cemtop GPF and filled to the required level with Nitoseal MS300. The Cemtop system can be applied to construction joints. However, if these joints move posteriorly, cracks may be reflected off the surface.

Investments

In some cases, Cemptop GPF should be protected by the use of an epoxy coating, eg Nitoflor FC130 or Nitoflor FC140.

Nitoflor FC130

Being permeable, this product can be applied on Cemtop GPF in the early stages. The first coat should be applied within 6 hours of the placement of Cemtop GPF. Nitoflor FC130 provides a chemically resistant pigmented seal layer. It is anti-dust, easily cleaned and resistant to the penetration of oils and liquids. One or two layers are required; See below.

Nitoflor FC140

If greater chemical resistance is required, it is recommended to apply Nitoflor FC140 on a single layer of Nitoflor FC130. See the Nitoflor FC130 / Nitoflor FC140 datasheet for further information on the product and its application.
