TAV™ (Thickening Activator)

Gives LRB Great Application Versatility.

TAV™ (Thickening Activator) gives LRB (Liquid Rubber Base) great application versatility. TAV™ (Thickening Activator) is a thick, blue colored, inert, odor-free, Gel-like additive specifically designed and formulated to be blended with LRB to adjust the viscosity or fluidity of LRB from a self leveling liquid to a ‘thickened mixture’, putty, or caulk like consistency for vertical, horizontal or inverted applications without sagging, running or slumping.

LRB/TAV™ mixture is used to patch/seal any joint, seam, crack, hole and profile rough areas whether vertical, horizontal or inverted.

TAV™ is mixed with LRB at a 1:2 ratio. 2-parts LRB can be mixed with 1-part TAV™ will create the thickest mixture possible. Less TAV™ can be used to create a ‘runnier mixture’.

A popular method of distributing LRB/TAV™ mixture is to use heavy duty zip-loc bags to produce a disposable applicator like a "mortar bag". This gives the convenience of caulking tubes without the high packaging cost. Large zip-loc bags can hold approx 1 gallon of total mixture.

LRB/TAV™ mixture is simply mixed, placed in the bag, clip the corner of the bag and allows quick application of LRB/TAV™ mixture.

Liquid rubber activator LRB/TAV™ mixture can be applied using a zip-loc bag, putty knife, trowel, flat squeegee or most any common applicator tools.

Spray Grade TAV™ - is more fluid than standard TAV™. Spray Grade TAV™ allows a vertical application of a smooth uniform 1/16" (62 mils) maximum thickness of LRB and TAV™ on vertical surfaces, in one application without slumping. Spray grade TAV™ is also used for roofing, flooring and flat roofing systems. Spray grade mixture may be applied by hand or by Ideal's custom designed spray/pump/ extrusion equipment.
