Do you think it would be better to buy a good quality sprayer for sealing drives and wash it out with white spirit all the time, or just buy a cheap one and throw it out after I have used it?

Richy,
depend one what type of sealer your gonna use,Polyurethane, acrylic or water based sealers.
Also most solvent sealers tend to rot the seals on the sprayer so you end up chucking it away,i found the thick stuff like resiblock is a buggar to keep a constant flow through the nozzle,your pumping like mad every few seconds.
I stick to roller,12'' sleves are cheaper and i find it less hassle,but this is my opinon

[Richy L]

how about if you are sealing blockwork. Wouldnt the roller just pick up the sand and put it down over the tops of the bricks?

so if I buy a cheapy sprayer to throw away after one job, it may not even last the one?
Ill be using Advanced sealing solutions stuff. http://www.advancedsealingsolutions.co.uk/product.php?productid=16134&cat=3&page=1

Viton seals essential so IK sprayers or similar best.

Roller is a good method. Use a medium pile solvent safe roller, minimum of 18" width. If using a roller it is recommended to go one way with first coat and another with the second.

Whichever method you choose it is essential that sanding is done correctly and all excess removed otherwise you will spread it all over the blocks.

The biggest negative with sealing is the UK weather.

 

[Richy L]

When you brush the sand in for blockwork do you blow the excess off with a leaf blower?

Would you reccommend I leave the sprayer completly then?

Do you seal block with with just a roller then? I dont see how the sand doesnt stick and come back out of the joints a little bit.

Richy,
this is where your common sense comes in not all block paving is the same,theres to many factors to list.
Ian's right though,alot depends on our english weather,just make sure,
1)  the damn thing is bone dry,
2)  theres no real need to use a leaf blower a good final sweep with a soft broom will do,make sure theres no sand on top
3) try not to over work the sealer just let it follow the natural contours of the block,again Ians method is not a bad idea.

Sounds daft,but your not actually rollering it on,but a bit more like troweling it like a plasterer thin but even.............................does that make any sense??

use resiblock 22, apply with watering can and squeegee, its the best stuff you can buy for joint bonding . its used on commercial premises like airports etc!

I don't use a very soft broom but quite a stiff one then it takes more sand away, then when you seal with a medium roller it should'nt touch the sand. I won't seal clay paviors because they never seem to dry and soak up loads of sealer, I've not sealed any drives this year because of the weather and the grief of it all

[Richy L]

ok cheers guys. I just want to ask as many questions as possible.
Im going to look for a day course near me

[drive surgeon]

i jacked sealing in ages ago due to weather and hassle and  possible comebacks.

[Richy L]

What do you think about this roller?
I know it is only 12", but will this be ok for the job?

Cheers mate.

Do you fill in cracks then? if so, what can you use?

[Griffus]

Hi Richy, if you are refering to Pattern Imprinted Concrete then to date we have not repaired any of these. We have occasionally quoted (we use a subbie for most repairs) but as stated none done. We have replaced the mastic when required. This is used between the expansion joints but we do this as a freebie as it only costs a couple of quid and takes a few minutes.

There are plenty of products on the market to use for repairs but if you do repair you will most likely have to add a colour pigment to your sealer so that the repairs are completely masked. Again, these can be had from most good suppliers.

[Richy L]

Hi Ian,
Yes it is for pattern imprinted.
He is having a terracotta tint to the resin.

Would these be ok?

Do you know if the tinted sealant will cover up the colour of the filler?

Speak to Advanced Sealing Solutions: -

http://www.advancedsealingsolutions.co.uk/product.php?productid=16142&cat=103&page=1

We have used their tints and they are good quality but you will need a descent sized container and a mixer attachment for your drill to mix. For PIC I would suggest their Ultra: -

http://www.advancedsealingsolutions.co.uk/product.php?productid=16135&cat=3&page=1

This will only cover about 50 metres per 25 litre tin so is not cheap. If using a colour do not spray, use a roller.

As long as the repair is a good one then the colour should cover OK but they'll advise you better than I can.

Speak to or email: michaelpalin@advancedsealingsolutions.co.uk

[Richy L]

thanks again ian,

could you send me an email please? i cant see your email address on your profile.

[Richy L]

What do you think of this as a use once - throw away jobby?

[Griffus]

No good, you'll have sealer leaking all over the place.

Viton seals are essential.
