Dry Bond

National Dry Bond is an adhesive mortar for installing all types of floor and wall tiles. It’s a unique specialized mortar with high sticking power, low water absorption, more chemical resistant for clean, long life and easy tile installation.

Advantages of National Dry Bond

	High sticking power
	Unique high bond strength (200% stronger than mastic type )
	5 times stronger bond than Portland cement
	Low water absorption
	Long adjustment time. More chemical resistant
	Easy to use
	No wet curing of tile required
	Plastic and long open time
	Water cleanable due to which cosmetics of tiles is not effected due to sticking adhesive material on their face
	The cracks caused due to exothermic reaction in cement mortar considerably reduced with the usage of National Dry Bond, due to which tiles are not cracked
	It does not affect color of the grout, cement effect grouts and changes their color i.e. grouts get black and yellow.
	If tiles are laid with National Dry Bond, grooves can be cleaned, and grouting can be done effectively. While with cement cleaning it is difficult and grouting is usually not effective.
	Time saving, less setting time
	Reduces number of handlings of tiles including soaking which not only reduces extra hassle but also reduces damage to the tiles.
