Lemax Seal is cement based supplied in powder form and formulated from Portland cement, fine quartz sand and active chemicals.The chemicals require the presence of water in the capillaries in order to penetrate and from sealing crystals.

Lemax products tolerate water and therefore substrates do not have to be specially dried out before the application can be made as with most solvent based resin systems. In fact Lemax must always be applied to damp surfaces and can be applied to surfaces weeping with water even against high water pressure.

Lemax Seal slurry applied to inside or outside surfaces will provide total protection to the concrete. Should the wall develop shrinkage cracks, the unique qualities of Lemax react with the moisture to seal off the leakage even against high water pressure.

WHERE TO USE
Lemax Seal is widely used in waterproofing projects on different construction structure. It has been used in waterproofing industry for more than 30 years.  Lemax Seal can be used for:
-  Water Tanks & Reservoir, Waste Plant
-  Basement (both external and internal wall)

Lemax Seal slurry can be applied to either internal or external wall surface to provide total protection to concrete. Usually, Lemax Seal is applied externally to waterproof the basement structure.

CHARACTERISTICS

SURFACE PREPARATION
- Thoroughly clean concrete surfaces free of oil, grease, paint and loose dust, mud and laitance and hose down concrete surfaces thoroughly.
- Check for honey combs in concrete surfaces and rake/hack out all honey combs to exposed concrete.
- For all constructions joints, v-groove to a depth of about 1” following the contour in line of the construction joints for walls and for floors.
- All corners between walls and floors shall also be v-grooved to allow fillet to be filled at a later stage.
- After checking for the honey combs construction joints and the fillets, hose down the entire concrete surfaces to be treated with clean water. Wait until all the running water has dried and when the concrete is still damp, the application of the first coat of Lemax can start.

MIXING
- Mix the Lemax Seal into water, the ratio is 2.5 parts of Lemax Seal to 1 part of water by volume.
- Stir the mixture of Lemax Seal in the water thoroughly and evenly for 3 minutes.
- It is advisable to use up all the mortar for every mixture. The subsequence applications shall use the new mixed Lemax Seal mortar.

APPLICATION
-  Check to ensure the concrete surface is touch-dry before applying Lemax Seal.
-  Lemax Seal can be applied by using brush or broom with fine bristles as well as by spray using spray gun.
-  For brush-on method, 2 coats at 0.75 Kg/M² per coat are normally required. The coats are installed in two passes. After the application of the 1st coat of Lemax at a rate 0.75 kg/m2, allow it to dry.
-  When the 1st coat is in tacky condition, the 2nd coat is then ready to be applied. The procedure of application for 2nd coat of Lemax is the same as the 1st coat except the application should be counter cross wised to the 1st application coat.
- In spray-on method, then one coat of 1kg to 1.25 Kg/M2 is normally sufficient by using spraying gun.
- After the entire application of Lemax Seal had been applied and all the construction joints, honeycombs and fillets have been done, hose down thoroughly the entire surfaces of the areas with water for 2 days about twice a day.
- Clean up the entire area and the Lemax Seal will work by its principal of penetration into concrete and waterproof the concrete surfaces.

HEALTH & SAFETY

Skin Contact: Wash off with clean water or shower.

Eye Contact: Treat the eyes with cold water. In case of irritation caused by fine dust, wash with copious volumes of water until the irritation disappears. Seek immediately special attention at hospital or medical center.
