Griptop MD is a three-pack solvent free polyurethane-based topping that provides floor surfaces with a seamless, hygienic and cosmetically attractive matt finish.

Usage

Griptop MD is flow applied by trowel to horizontal surfaces and has very good durability towards pedestrian and vehicular traffic. It also has very good resistance to many of the chemicals commonly found in an industrial environment (consult our Technical Department for further details).

Griptop MD can be supplied in a variety of colours (consult our Sales Department for further details).

Application Instructions

SURFACE PREPARATION

The surface must be clean, dry (less than 75% RH measured by hygrometer) and free of laitance (see the DCP Guide to Surface Preparation for further details). To ensure a good bond to the substrate, a 4mm deep x 3mm wide rebate must be cut around the edges of the floor, 150mm from the walls, doorways, finished edges, plinths, etc and running parallel to them.

For treatment of surfaces containing expansion joints, consult our Technical Department.

PRIMING

Surfaces must be primed with Strongcoat Primer prior to application of Griptop MD (see Strongcoat Primer data sheet for further details 0.

More than one coat of primer may be required for highly porous or textured surfaces.

For surfaces with RH greater than 86%, prime with 2 coats of Strongcoat DPM and to fully cure before priming with Strongcoat Primer.

MIXING

Taking care to ensure that the bottom and sides are thoroughly scraped, transfer the entire contents of the Griptop MD Hardener container into the Resin container and, using a Jiffy-type mixer attached to a slow running electric drill, mix for approximately two minutes. Once the Griptop MD Hardener and Resin have been mixed, transfer all the mixed material into a Casco or Creteangle-type mixer, taking care to ensure that the bottom and sides are thoroughly scraped. Start the mixer and transfer to it the entire contents of the Griptop MD Filler container, taking care to ensure that these are completely dry and lump-free. Continue mixing for approximately two minutes.

Never mix Griptop MD by hand as this could lead to areas of uncured material.

APPLICATION

Once mixing is complete, transfer the Griptop MD to the primed surface and, using a straight-edged steel trowel, apply it evenly.

Note: Griptop HD is not colour stable and may discolour on ageing and exposure to UV light, especially with light colours. This will not adversely affect the performance of the product.

WORKING TIME

Griptop MD has a working time of approximately 15 minutes at 20°C.

Never leave the mixed Griptop MD kit to stand for any length of time before application, as this will considerably shorten its working time.

FINISHING

Whilst still wet, thoroughly spike roll the Griptop MD.

CLEANING

Once mixing, application and finishing are complete, tools can be cleaned with a suitable solvent.

CURING TIME

At 20°C, Griptop MD can be opened to heavy wheeled traffic after 24 hours. At the same temperature, it should be allowed to cure for five days before exposing it to chemical contamination (consult our Technical Department for details of curing times at other temperatures).

WORKING CONDITIONS

Griptop MD should not be applied at temperatures less than 10°C.
