MORESTEAD MORTAR

Data Sheets

Morestead NHL Mortar Data Sheet

Morestead Mortar is natural sand mortar. Made with Morestead 3mm sand and Natural Hydraulic Lime. The Morestaed sand has been sieved to the ideal size for repointing and laying bricks.

The colour is a buff yellow and the joints can be finished with and open texture exposing the minor variations in particle size. By dragging the mortar with timber and using a soft brush an open texture is achieved. The notes below explain the method in more detail.

Morestead Mortar is a dry powder product mixed with water on site for building and pointing brick, stone and flint. It is breathable and is ideal for old buildings because it allows moisture in the walls to escape. We also supply as a traditional wet putty mortar for pointing soft and fragile brick and stone.

You can request sample mortar biscuits for matching on site including this Morestead Mortar and other coloured Lime Green Mortars that we supply.

Laying bricks, stone or flint

Lime mortars require longer curing times than cement mortar, but the methods and principals of laying are similar. There are many ways to finish mortar joints. We prefer a joint which is square and set back off the sharp brick arris by a mm or two. After cleaning off wait for the mortar to begin to stiffen and drag with square end timber batten (not a bucket handle tool) the timber will compress the joint, remove excess mortar and leave an open texture with some exposed aggregate. This can be left or finished with a soft brush. This method is simple and leaves a neat flat joint whereas a bucket handle tool can leave a concave joint with a sheen on it.

Repointing

Rake out to a depth that is approximately twice the height of the joint. Remove all dust and loose material from the joints. Dampen the joints with a spray of clean water before repointing in order to reduce the suction from the brick.

Repointing with a small tool or an appropriate pointing tool that easily fits into the joint. The mortar is pushed firmly to the back of the joint and built up to the front of the brick/flint/stone. This way the front face of the bricks stay clean which is not possible if the tool does not fit into the joint. Do not try to clean mortar away from the bricks before it has crusted otherwise it will be forced into the pores of the brick. If it has crusted it will drop off the brick easily leaving the face clean.

When the mortar is beginning to crust the joints can be dragged with timber to them leave square, with open texture and with some exposed aggregate. This can be left or finished with a soft brush.

Curing

Do not use in temperatures less than 5 degrees or over 30 degrees. Protect mortar against the effects of drying winds, strong sunlight, rain and frost. In warmer weather gently mist spray with water after application and cover if required with damp hessian. In cool weather cover fresh mortar with protective sheeting to help avoid frost damage.
