Walttools new Tru-Block sealer utilizes exclusive water based silicone technology that provides long term environmental protection without a hint of presence to the eye. This is ideal for the vertical concrete contractor where it is imperative that rock and stonescapes appear completely natural and free of any shine, yet the work must be preserved and protected from the elements.
The ultra low VOC formula performs very well against costly RTV silicone alternatives and avoids the hassle of dealing with harsh solvent based products.
Tru Block is good for almost any porous concrete, stone or block surface where discrete protection is needed. It can be applied by spray coat, brush or roller.
