What is pointing mortar

While our mortars are meant for gunning the addition of mortar plasticiser can help the mortar flow better. Sorry to bother you, I been using your bricks for a few projects now and I love them but I was wondering can I use your slips for an internal floor.

It will be in a hallway with underfloor heating. Thank you. Yes you can use all our slips for internal flooring and we are going to be launching some different size formats for flooring in the near future.

You can also use slips we produce externally for i. Your email address will not be published. This site uses Akismet to reduce spam. Learn how your comment data is processed. Is it just sand and cement? Yes it is but there are a few other things to consider. So what makes this different from standard sand and cement mortar?

Cracking and deterioration can also occur if thermal expansion is not accounted for. This is more common in older buildings that were constructed without expansion joints. Contraction and expansion are very hard on mortar, particularly in areas that are subject to extreme temperature swings. These signs should not be ignored. The process of repointing starts with surface preparation. The joints and surface are cleaned of debris, and thoroughly wetted.

Once the surface is prepared, new mortar is carefully placed in the joints using a small trowel. The mortar joints should then be tooled to match the desired profile. There are several different types of pointing profiles that can be achieved.

Pointing is the finishing of mortar joints in brick or stone masonry construction. Pointing is the implementing of joints to a depth of 10 mm to 20 mm and filling it with better quality mortar in desired shape. It is done for cement mortar and lime mortar joints. In exposed masonry, joints are considered to be the weakest and most vulnerable spots from which rainwater or dampness can enter. All the joints in masonry are raked down to a depth of 20mm while the mortar is still soft.

The joints and surface are cleaned and then thoroughly wetted. After preparing the surface as mentioned above, mortar is carefully placed in joints using a small trowel. The placed mortar should be of desired shape.

Whenever the fresh mortar is placed in the joints it should be pressed hardly to gain strong bond with old interior mortar. Care should be taken while using ashlar or 1 st class brick work otherwise the mortar does not cover the face edges. The pointed surface is kept wet for at least a week or till it sets after application. In this type, mortar is pressed hard in the raked joints and by finishing off flush with the edge of masonry units.

The edges are neatly trimmed with trowel and straight edge. Different types of pointing are used for brick masonry and stone masonry work which we will discuss in this post. Pointing is far more economical than plaster, and thus in the case of storage of cement, an external surface can be finished with pointing.

Right Pointing prevents the entrance of water into the wall within joints. Pointing may be done in the lime mortar or cement mortar. Flush pointing is the most accessible type of pointing and is generally utilised in brick masonry and stone masonry. In flush pointing, mortar is pushed into the raked joints and joints are made flush with the edge of the stone or brick to provide a uniform appearance.
