Latachink

General Info

PRODUCT
Latachink is a flexible, mortar textured sealant, specifically designed for use in log homes.  Latachink chinking is a single component, room temperature gunning, non-sag sealing compound for use in applications demanding the ultimate in adhesion and weathering.

PRODUCT DESCRIPTION
Composition:  Acrylic copolymer base.

Basic Use: Latachink is used in log joints where a positive, weather tight seal is needed, and a neat, mortar-textured finish is desired.  Latachink is available in a wide range of colors.

SURFACE PREPARATION
Surfaces:  Surfaces should be clean, dry and free from loose or foreign materials.  Do not apply to oily or glass smooth surfaces.  Some paraffin based stains and sealants may cause adhesion problems (if in doubt, test small area for adhesion).  When necessary, a pressure washer may be used to clean log surface.  Caution  –  a pressure washer can cause damage to log surface if not used properly.  Consult manufacturer’s directions for proper usage.  Wire brushing may also be done to clean adhesion area. Latachink may be applied to slightly damp logs.

Application: Temperature:  Surfaces should be between 2o C and 22o C when applying Latachink. Avoid chinking in the rain or when rain is imminent.  Important:  DO NOT FREEZE.

General Application:
1) Fill spray bottle with release agent for smoothing over the Latachink (water or 50% denatured alcohol and 50% water mixture).
2) Fill bulk caulking gun or bag (cake decorating type) with Latachink (tie large end of bag securely with string).
3) Holding gun or bag firmly against backer surface, apply enough material between top and bottom log so that finished tooled thickness will be 1/4″ tooled.
4) Apply material to only as much area as can be reached without moving.  This will prevent the material from forming a “skin” before it can be tooled.  When chinking in very hot weather, it is recommended that the chinking be applied to the shaded side of the house first.
5) Holding sprayer in one hand and finishing tool in the other, mist spray Latachink and tool intermittently.  Work Latachink tightly against logs to form a continuous smooth watertight seal.  It is essential to form a good seal against both upper and lower logs.  If more than one bead is applied, be sure to work material well to blend beads.
Backer Rod Application:   When applying Latachink Chinking to new construction, or to previously unchinked structures, it may be applied over a foam backer rod.  Closed-cell backer rod is the ideal   type of material to use.  Open-cell backer rod is not recommended as it will not release the chinking and it may cause failure of the sealant at the edges.

Coverage:   The following guide is offered to assist in estimating the number of pails that will be required in estimating the number of pails.  Measure the total number of linear feet of log joint, exterior and interior, and estimate the average width of the finished chink joint.

Finished Joint

Feet Per 20 Litre

Width

Pail

          1″               325′
          1-1/2″               250′
          2″               175′
          2-1/2″               125′

Thickness of chinked joint should be 3/16″ – 1/4″.  Do not exceed thickness of 1/4″.

Repair:   If part of a seal is damaged, cut out the damaged portion and, making sure no contaminants are present, re-seal with new material.  The new chinking will adhere very well to the old chinking mass, providing the surface is clean and dry.
