H‐4 200 is comprised of consistently measured and blended sand and Virginia Lime Works Building Lime 200. Set Time 4 hours Application Technique Tuckpoint, Trowel Where to Use • Areas that experience harsh winter conditions • Repointing pre‐1940 masonry • Repointing porous masonry units • Laying porous masonry units • Laying or re‐pointing limestone • Bricklaying and Stonework • Chinking (for log cabins) Features • Excellent vapor permeability • Historically correct • Contains no cement, latex or acrylic • Factory blended for consistency • Higher strength than H‐4 150 • Just add water • Green product – absorbs CO2 Packaging and Yield 50 lb heavy duty polyethylene bag 0.625 cu ft Will lay 25 standard bricks at ½" x 4" or repoint 62.5 square feet of brickwork or 180 linear feet of stonework at ½" x ¾". These figures are approximations. Surface Preparation Areas to be repointed should be clean and free of dirt, debris, grease, and oil for best possible bone. Loose or deleterious existing mortar should be removed to an approximate depth of 1.5 times the width of the mortar joint. Work should be thoroughly dampened to prevent flash curing of the work. To test the substrate’s absorption, place a drop of mortar on the surface. If the moisture is pulled in instantly, additional dampening is required. If the moisture rests on the surface for more than two seconds then it may be necessary to allow the work to dry out before application of mortar. Mixing When mixing small quantities, place H‐4 200 into a tub or bowl, slowly add water and mix to desired consistency (like a thick peanut butter). For mixing a whole bag, slowly add 0.85 gal of water and blend, slowly adding additional water as necessary to achieve desired consistency. Mix for at least 5 minutes. Please note that adding too much water can cause mortar to shrink, crack, and/or change color after curing. For Bedding Masonry Lay a bed of mortar to sufficiently create full bed (horizontal) joints and “butter” brick ends to form full head (vertical) joints. Do not move or adjust units after the commencement of set, which can cause loss of bond between mortar and masonry units. If adjustments are deemed necessary remove both the masonry unit and the bed, and re‐lay using fresh mortar. For Masonry Repointing Joints greater than ¾” should be re‐pointed with an initial lift to bring the joint depth to a uniform thickness. Pack mortar firmly against the previously placed mortar by applying firm pressure to ensure close contact between the lifts. If pointing in lifts, roughen the surface to provide keying between applications and allow mortar to become thumbprint hard prior to reapplication. When finishing mortar joints it is often preferable to match the original joint profile. Reworking H‐4 200 can be reworked for up to 3 hours. If a significant amount of water is needed to rework the mortar, the hydraulic set may have started and the material should be discarded. Curing Mortar work should be protected from rain and excessive sun or wind for at least 7 days. Mortar work should be protected from freezing temperatures for at least 28 days. In some cases mortar work may need to be protected from freezing temperatures for several months. 877-JETOMES 538-6637 Fax (708) 653-5101 www.jetomes.com For concrete repair and restoration Made in the USA by JE Tomes, an American Owned and Operated Company 2513 W. 140th Place • Blue Island, IL 60406 H-4 200™ Clean Up Ensure that all work is properly protected prior to cleaning. Maintain clean surfaces on the face, sills, ledges and projections of masonry on a daily basis, and with a trowel, strike off minor dabs of adherent mortar from masonry faces. After mortar has achieved thumbprint hardness, lightly brush masonry to remove small mortar burrs from joints and masonry edges. Manual cleaning of masonry can be effective by using water and soft bristled brushes to remove mortar smears. Light pressurized spray (less than 300 psi) can be used with caution due to the fact that over saturation of the masonry could lead to moisture migration. JE Tomes does not recommend cleaning with masonry detergents, however, if such measures deem detergents necessary, contact detergent manufacturer for protocol when cleaning “PURE LIME MORTAR” and test the treatment in small inconspicuous areas to determine its effectiveness and to ensure no damage occurs to the building fabric. Tools can be cleaned using conventional methods and properly protect any unused product from moisture and freezing. Opened bags of H‐4 200 can be stored in sealed pails for up to 6 months from the date of purchase.
