In a 5-gallon bucket, combine water with Sakrete Type N Mortar Mix. The mortar mix should contain Portland cement and sand, with no large rocks. Start by adding a couple of trowel-fuls of mortar mix to the bucket, then gradually add water. Stir the mixture with a wooden stick until it reaches a thick, paste-like consistency. It should be soupy enough to move slightly when the bucket is tilted but not like a 'bowl of soup'. If it's too soupy, add more dry mix until the desired consistency is achieved. For larger batches, a paint stirrer on a drill can be used, but for this small amount, a stick is sufficient. The correct consistency allows it to stick to the mixing stick when turned sideways, but still fall off a little.
