Smith & Rodger’s Blockade proves popular with Trade customers

Smith & Rodger launched its latest performance product– a specialist shellac sealer primer, last summer and it’s proved to be a hit with trade customers.

Blockade is a multi-surface primer that will easily cover the toughest stains and provide a base that can be overcoated with most paints. Stocked through a number of decorators merchants, the feedback from users has been overwhelmingly positive.

Managing Director Ian McAslan said:

“We were delighted to unveil our latest formulation to experienced painters and decorators, and have been blown away by the positive response to Blockade.

We have been making specialist finishes for over 140 years, and launched this product to make our customers lives easier and of course remains extremely price competitive!”

“Blockade has been rigorously tried and tested by professional painters and we are confident that, once you have worked with it, you will be happy to switch from your favourite brand.”

So what have the trade being saying about Blockade?

“When decorators are begging their suppliers to stock it you know it’s a winner. We know when a paint is good” Kevin, TDS Decorating.

“New year, new product, this @Smith_Rodger blockade seems to have covered an old water stain on a ceiling in one. Much less drag than other shellac based blockers, and I’ve successfully managed to clean the brush out…” Pete

“I was using Blockade today on some water/mould stains, held back any marks well, applied 2 coats in quick time. It has a much better open time & slightly thinner consistency than other similar brands. So far, so good” Christophe

“I always carry a tin of @Smith_Rodger #blockade #stainblocker (plus many other uses) in my tool bag! There’s not many jobs I do where I don’t need it somewhere” Nick

“It’s brilliant” Ricki

@Smith_Rodger We tried out Blockade stain block over the last two weeks on permanent orange marker, water marks & even on tiles. Very impressed with the results. For the price I’d recommend hands down!” Paul
