Block out the wet with paint-on shield
WEATHER and water proofing of rough blockwork, indoors or outdoors, is claimed for a paint-on protectant from Tecnishield.
The Lancs-based firm says Blockshield is an alternative to cement rendering, which is capable of sealing, filling and skimming all types of block. It can be used either as a final structural finish or as a ready primed surface for a final top-coat of paint.
Blockshield is supplied in 25kg (55lb) plastic pails containing 2 x 12.5kg units of the product – resin liquid and powder – ready for mixing. Price is about £2/sq m (18p/sq ft) (01282-619601).
