Sika SikaBond SBR, 2.5L

yeah i should have got smaller bottle as hard to get a container up a scaffold without spilling

Does what it says and makes a good primer on open concrete.

A runny latex based liquid. I'm using it to seal the plaster of Paris layer of a pig garden ornament. Have used 2 layers, and then will use SBR as Admix with thin set. Has been suggested I then seal again with 2 layers - should be fully waterproof by then! Using paint brush, same one more than once, but otherwise will throw away. Use plenty of polythene ground sheet, as it tends to spread. I don't like wearing gloves - mistake, as it is quite difficult to completely remove - leaves a very thin layer despite thorough washing - will wear off over time! Sadly the bottle arrived with the corner with the lid, bashed in, and some of the contents leaked not only to the cling film, but a little into the bubble wrap. Overall it had appeared very well wrapped - but it wasn't sufficient for transit. As a product it appears to be doing it's job. I have informed the retailers of the problems in packing, so hopefully others won't experience the same. Not competent to give any technical detail as I am a mosaic artist, not a DIY expert! I WILL NEVER BUY THIS PRODUCT AGAIN OFF THE INTERNET. I put the container on a new storage shelf and hadn't realised for a fortnight that the container was now leaking. 3/4 of the contents spread over the shelf sticking every other item on the shelf so they were extremely difficult to move. The base of the large cardboard box won't budge. It is the most unpleasant job I have had to do as what every you touch gets stuck together and makes more mess.. The knife I was using for scraping is now impossible to clean. Because of the height of the shelf, and having to lean across a metre wide surface, my blouse is now ruined. Having washed my hands with swafaga, I still have the effect to get rid of. What was a pristine bespoke built storage trolley costing £400 delivered a fortnight ago, now has a permanently stuck piece of cardboard stuck on it and it's now unwanted waterproof stain. You will understand my decision. I recall seeing the product locally, but thought it easier to get off Amazon. What a mistake! The £2 refund I accepted from the seller when I reported the package problems just doesn't cover this sort of damage - will try insurance accidental damage clause, but this will affect my premium next year.

Excellent product, suitable for outdoors and wet/damp areas, whereas PVA for indoors, easy to use, highly recommended, no need for plastiser

I've been using this for years in DIY projects. Mix with water before using it with mortar and concrete. It toughens it and waterproofs the mix. Google for all of its uses.

The product is good BUT, despite following instructions the top refused to unwind. Had to pierce two holes to pour into another container. For this reason I would not recommend.

Excellent product with swift delivery. Thanks again.

Item was great
