Repointing Sample Clauses

Repointing. The repair or repointing of chimneys or other masonry features with the design, size, shape, materials, and repointing to match the original in color, texture, and tooling, and, for historic properties, following the recommended approaches in the most recent edition of Preservation Brief No. 2

Repointing. Repointing of masonry and stone if the old mortar is removed by hand, i.e., no power saws and the new mortar is the same color, tooling and strength as the historic mortar, as per the guidelines in Preservation Brief #2.

Repointing filling and finishing of masonry joints from which mortar is missing has been raked out or has been omitted.

Repointing i) Partial repointing of any individual wall or any number of them is covered by this Agreement. ii) Raking out of existing mortar should be to a depth of min 25mm or twice the width of the joint, loose material then brushed out, and the surfaces well wetted before placing of new mortar. iii) It should be possible to rake out loose mortar by hand without damaging the brickwork. Where this is not possible, a slit can be carefully machine-cut along the middle of the joint and the mortar on each side of it tapped off. A trial of this method should be attempted first, and if any damage to the brickwork still occurs (including the cutter over-running on to the brickwork), the work should not be continued. iv) Resilient mortar of any kind that is resistant to the methods above is to be left insitu. v) No cement is to be used in the new mortar. Its mix is to be 1 part NHL 2 hydraulic lime putty to 3 parts well graded sand without synthetic colourants. vi) In times of the year when an accelerated set is required, then only brick dust, stone dust, or HTI powder (High Thermal Insulation powder obtainable as a by-product from Steetley Refractories Ltd) may be added to the aggregate, keeping the mix to the same proportion. However, it is likely that the setting qualities of the hydraulic lime will preclude the need for this. vii) Colour when set should match the original mortar when it was new, using the existing as a guide to this, and to be achieved by the selection of the sand. viii) The outer face of new pointing should match that of the original work. On the initial set, the new mortar is to be tamped with a bristle churn brush to expose the aggregate. Struck, beaked, or strap joints are not acceptable in new work. ix) Brick arrises are to be cleaned of smears immediately on final set. x) No mortar is to be mixed or placed, nor the prepared joints wetted, when there is a risk of frost. When such risk is present, the finished work is to be protected with hessian during the setting process, and likewise in periods of intense direct sun, when the hessian should be regularly dampened to prevent premature drying. xi) Before any repointing is carried out, a minimum of four sample panels are to be executed in an agreed location, and the constituents of each recorded for reference. Repointing is to match the samples approved by all parties to this Agreement. xii) The samples may include trials of applications to the mortar to tone it down (for example, applying natural y...
