foam: how to remove from brickwork
Hi,
I discovered that when my carport was built, the builders left gaping holes where the joists entered the brickwork of the house. I decided to fill these holes with some foam. I bought the low expansion type because I know how much trouble foam can be Unfortunately even though I used the low expansion foam and even though I underfilled the holes to allow room for expansion, the foam expanded a lot and some dripped down the walls. It looks like an ill snail has crawled all over it! The problem is that I have these bricks with a rough surface, IIRC they are called "rustic" bricks. I think they are a PITA because there rough surface is a magnet to get things like foam stuck in and its not very gentle on your knuckles either I tried very light sanding with a 240 grit paper and it removes some of the cured "trail" and I have tried scraping the grooves of the brick clean with a Stanley knife but it is a slow process! I did try foam eater but I think that made it worse because rather than have to remove a narrow foam trail, I now have a broader foam eater trail to clear away ;( I am thinking of using a wire brush. Would that work? I'll have to go and buy one, I threw my old one away. I suppose a powered wire brush on a drill would be too powerful and ruin the bricks? I found that using a hole pipe blasted a little off. If I borrowed one of those 100bar jet things do you think that would work? Thanks in advance. |

Depending on the hardness of the brick, you either scratch the brickwork, or the metal rubs off the brush leaving a metalic finish on the bricks. You could try it in a hidden area. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Nip to the chemist and buy some acetone (or you can use nail varnish) and the may do the trick - (it doesn't always work on porous materiala). |

Nice spotting Steve, the old finger pressed the send button before the brain was engaged (or signature typed) - and as for the "wannabee terrorist" suspect - well if you take a photograph of a badly parked police car now, you have a good chance of getting arrested under the Terrorism Act (it was done recently to a person who did just that).

You'll need to brush if frequently after this process starts to expose more to the UV. Of course, this assumes that the wall gets some sunshine.... R. |

It will go yellow/orange in a matter of days. |
