Thanks DM hi mate it needs rendering but when you render it you need to put some waterproofer in the mixer when you are mixing you can buy the waterproofer from and builders merchant hope this helps Quote Link to post Share on other sites
dannys lad 0 Posted January 6, 2010 Report Share Posted January 6, 2010 (edited) dont think so mate with it only been a single block wall rain is always gonna come in thats why a house has a 50mm cavity so when the rain dose come through it drops down the cavity then on to the dpc tray then out of the weep holes . dont think rendering will make a difference mate it will just soke through same as the block. but a might be wrong bud did you put dpc (damp proof corse) on you bottom corse of block??

dog fox 16 Posted January 6, 2010 Report Share Posted January 6, 2010 (edited) like bondy said mate render it and add a good ltr of waterproofer to every mix you make ,first a good scratch coat with waterproofer and then a good top coat with waterproofer in it ,leave scratch coat for a day or so before you put second coat on and when second coat is just about set rub it over with a damp sponge this will seal it all nice and strong and you should end up with something like this,dont do it while the weather is freezing wait till it gets a bit warmer Edited January 6, 2010 by dog fox Quote Link to post Share on other sites

tsteve9999 456 Posted January 6, 2010 Report Share Posted January 6, 2010 Have you got gutters fitted? If rains pouring off the roof down the wall it will stay wet even with waterproofed render. Quote Link to post Share on other sites
wint 3 Posted January 6, 2010 Report Share Posted January 6, 2010 What about just painting it with a masonary paint ?? Andy Quote Link to post Share on other sites
rob.i 26 Posted January 6, 2010 Report Share Posted January 6, 2010 If you cant render it use good thompsons waterseal and paint Quote Link to post Share on other sites
dannys lad 0 Posted January 6, 2010 Report Share Posted January 6, 2010 like bondy said mate render it and add a good ltr of waterproofer to every mix you make ,first a good scratch coat with waterproofer and then a good top coat with waterproofer in it ,leave scratch coat for a day or so before you put second coat on and when second coat is just about set rub it over with a damp sponge this will seal it all nice and strong and you should end up with something like this,dont do it while the weather is freezing wait till it gets a bit warmer nice set up there dog fox Quote Link to post Share on other sites

BULLDOUG 199 Posted January 6, 2010 Report Share Posted January 6, 2010 A good sealacrete will help also, on top of whats been suggested. ATB Doug p.s great set up, looks mint. Quote Link to post Share on other sites
steptoe jet 4 Posted January 6, 2010 Report Share Posted January 6, 2010 dont put waterproofer in scratch coat only top coat. Quote Link to post Share on other sites
BULLDOUG 199 Posted January 6, 2010 Report Share Posted January 6, 2010 dont put waterproofer in scratch coat only top coat. Good point as the second coat will not bond. i would light render one coat, tyrolene and then sealacrete, all water would be repelled. Quote Link to post Share on other sites
dog fox 16 Posted January 6, 2010 Report Share Posted January 6, 2010 if you dont put waterproofer in scratch coat it will crack and blow off in time trust me, been a plasterer for 15 years mate ,the top coat with just get all the water sucked out off it and will not set how its supposed to ,with water proofer in scratch coat the top coat will hang all day and set how its suposed to,a lot stronger and you get a proper finish otherwise it will go all bread crummy ,you can also use an acclerator / frost proofer as surgested but water in these conditions will still swell and then it will just blow off the scratch coat ,you need a few days of a nice temperture to do the job right or your just waisting your time ...hope this helps Quote Link to post Share on other sites
