Surafce
Preperation deteriorated and loose concrete, form release agents, oil, grease, laitance, dust, dirt and areas using OBS recommended material. cracks larger than 2 mm with DRYTEX CEM HF or any other material recommended by OBS Embed a strip of reinforcing mat into the wet DRYTEX CEM HF and apply a second coat to fully cover the reinforcing mat ( Consult OBS technical support to select the suitable reinforcement material according to the substrate).

Mixing
Mix in a clean container by slowly adding the powder component to the liquid component and mixing with low speed drill and mixing paddle. Gradually add the powder to the mixing liquid while the drill is running. Pot life is 60 min @ 35 °C.

Application
Can be applied conventionally by brush ,roller or spray equipment.. It is recommended Membrane has excellent high build properties, and can be built up to 2000 micron wet in one application. However from a curing point of view and dependant on weather conditions at the time of application, it is more pertinent to apply and build up the membrane in two or more coats, to allow quicker cure in each stage. The thicker the application the longer the cure.

Coverage
0.8 litre of mixed membrane applied wet at 600micron thick will cover 1-latent curing mechanism activated by water loss happens in 3 stages. Firstly there is the initial evaporation of the majority of water in the system, followed by the second stage where the surface skins over and cures. The third stage (which takes a minimum of 6-2days) is to complete cure and gain of cohesive strength. The application of the second coat can proceed after stage two. This is a two stage system, inclusive of the necessary bond breaker requirements being addressed.

Limitations
Do not apply DRYTEX CEM-HF when the temperature is expected to be below °4C within 48 hours, or when rain is imminent.

Packing
15 KG POWDER + 5 L LIQUID

Storage And Transportation
DRYTEX CEM-HF, when stored on pallets in dry, cool area from moisture and direct sunlight, has a shelf life of 12 months. The liquid Component B must not freeze.
