Should windows and window frames be masked when softwashing?

November 02, 2019

Benz Lightning Cleanze softwash biocide based on sodium hypochlorite (SH)

A customer asked us: "A surveyor has specified the softwashing of render with Benz Lightning Cleanze and to mask the windows. What is your experience of masking windows and window frames when applying Lightning Cleanze at 5:1 on render, with some overspray and run-off inevitably going onto the windows and frames?"

Ben replied: I've never masked up windows and I've never had any long-term issues with window frames or the glass. In hot weather the glass can look unsightly for a short time until you rinse off but our softwash products have never caused any damage.

A temporary colour change can occur on white uPVC – for example on certain frames, facia, and soffit – in hot weather and strong sunlight. This is caused by the increased reactivity of Lightning Cleanze in heat and direct sunlight. The uPVC will return to normal after 2 to 48 hours, depending on the strength of your mix.

To stop this happening I have a hosepipe or pressure washer with rinsing nozzle on hand ready to rinse off any product that gets on the frames..

My advice is to treat a small, out of the way, test area of a window and window frame. Then show the surveyor and explain that this is all that will result from overspray onto the frame.

Quick tip: If the surveyor insists on using masking tape, then check the windows and frames will not react to it. Also, in my experience of painting houses, it is best practice to get the tape off as soon as possible because the adhesive can bake onto the frames in hot weather and it can be a pain to remove.

We hope this information is helpful,

Cheers,

Ben, Leo and Fiona

PS: After completing the first softwash treatment, put your customer on a "Clean & Maintain" ongoing maintence programme.

Customers will enjoy a permanently clean property and contractors will enjoy a steady stream of repeat business. A win-win arrangement for both customer and contractor.

Soft washing an artifical slate roof with Benz Bio Cleanze
Why pressure (jet, power) washing a roof is NOT a good idea

(Due to logistic problems associated with the government restrictions around Covid-19 this is a written, not video, Trade Tips post this week)
===========================

A customer asked us, if it would be a good idea to pressure (aka jet, power) wash a roof prior to treating it with Benz Bio Cleanze.


That's a reasonable question.

You could jet wash a roof and then treat with Bio Cleanze.

But why would you?
