[quote]Hi to ALL readers, We are now in the position of wanting to smarten the outside of our house up, it was built in 1981 and I do not think much has been done to the external walls with regards to dec...[/quote] Hi once again, Many thanks to those people that have responded to my questions,I do know, that what ever I have to do, to get the external walls looking like new again, will entail some hard work, to Liz,they are somewhat 'rough render' not smooth, also all our gutters are in good condition,......not going off the subject, I did notice that where my daughter lives, the overlapping roof tiles, (not the new ' L' shaped ones that come down over the external render) the old flat type that are quite common for finishing the end of any roof off......which has about a 3 inch overlap, does create a problem with rain water dripping down off each tile.......being persistent over the course of time, does in fact wash the colour out of the walls, causing a streaking affect,which really is another eyesore.Our house has blackish marks, which are on a light cream paint? colouring? also on other parts go greenish when the weather goes damp, the previous owner did say, that this greenish colouring does disappear when it gets hot......this we have found to be true. Like one of your readers,we had a chap come knocking at the door,wanting the job of decorating the outside walls of our house,when I asked him about a GUARANTEE in writing, he looked the other way, and said he would get back to me, which to this day,I have not heard from him.I shall press on,I have looked at the water based materials which are on the market at the present time,these are my favourable choice, oil based is not a option that I will consider,(knowing what the heat of the sun can do to oil based paints) It is a fact,that in this life, you get what you pay for!so what I finally choose to do the job properly will be expensive, this I know! I are not made of money,that is why it is so essential in doing the job right in the first place, Some water based paints give a TEN YEAR GUARANTEE, which is good,but this guarantee would, I rather think, be invalid if the base in which the paint was put on was not prepared properly, this again is another reason why I seek the advice of experts in this field, there must be somebody out there who can help me, your views are welcomed no doubt, by ALL readers, Thanking you in advance. SUNNY.
