Concentrated one-coat mortar, method for making the same, and method for applying the same

An improved method of applying a concentrated one-coat mortar in high and low temperature conditions to avoid cracking comprising the steps of:

• mixing by weight approximately 40% cement, 54% calcium carbonate, 2.5% sand, 0.6% hydrofuge agent, 1.8% cellulose fiber, 0.4% cellulose ether, and 0.5% dispersible pulverized resin to provide a mortar;
• mixing by weight in 1:1 proportion the mortar with sand or pulverized aggregate and further mixing with water to a consistency for prepared mortar;
• and
• applying the prepared mortar to a rough concrete surface to form a finished exterior surface without cracks.

A method of making a concentrated one-coat mortar especially suited to avoid cracking in high and low temperature climates wherein the improvement comprises mixing the following components of the concentrated one-coat mortar by weight in approximately following proportions:

• 40%, within a range of +/−12%, cement;
• 54%, within a range of +/−16%, calcium carbonate;
• 2.5%, within a range of +5%/−1%, sand;
• 0.6%, within a range of +1%/−0.6%, hydrofuge agent;
• 1.8%, within a range of +3%/−0.8%, cellulose fiber;
• and
• 0.5%, within a range of +1%/−0.5%, dispersible pulverized resin.

A concentrated one-coat mortar especially suited to prevent cracking when applied in high and low temperature conditions, comprising by weight approximately:

• 90% calcium carbonate, having approximately 20-25% of 0.63-0.66 mm granularity and 75-80% of 1.8-2 mm granularity;
• 4% sand;
• 1% hydrofuge agent;
• 3% cellulose fiber;
• 1% cellulose ether;
• and
• 1% dispersible pulverized resin.
