H-4 200™ Historic masonry mortar
H-4 200™ is a factory blended hydraulic lime mortar used for laying brick or stone
and for the restoration and repointing of historical masonry and porous masonry
units. 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.

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.
