Rated 1 out of 5 by from Top coat peeling off I have been using Valspar wall paints and was happy with them so I have decided to use Valspar Trade Solvent Based Primer & Undercoat together with Valspar Trade interior Wood and metal paint. I have spent few weekends preparing and sanding surfaces. Following instructions on the tin,I have painted the Valspar Trade Solvent Based Primer & Undercoat over my skirting boards and doors and waited for it to dry. The coverage wasn't great. Then I have painted over with few coats of wood paint. Now it is all peeling off.

Rated 1 out of 5 by from Won't dry! I used this yesterday, stirred and applied. Nearly 24 hours later and it's still really sticky. No colour coverage, just opaque. I was painting my mother's bookcase which is quite old but probably worth about £200 and was looking a little 'tired' - however, now I feel it's ruined. Will this undercoat ever dry? My mother is going to be really upset. Will you compensate to buy a new bookcase for her I wonder? I have been using various primers and undercoats for years and never had this result before. Not happy!

Rated 1 out of 5 by from Not a good trade undercoat/primer I bought this for decorating 3x bedrooms. Found the paint to be very runny once fully stirred. The finish is not flat, more like gloss paint very shiny. Does not cover very well and has to have at least 2 coats possibly 3. Not good for a primer undercoat

Rated 1 out of 5 by from Disappointed I am so disappointed with this product especially as I spent time checking products against each other and finally chose Valspar. But it's like water, thinner than I would have thought for a primer/undercoat. I have painted one coat up to now but I'm probably going to have to do 3 coats. You state 'excellent hiding power'...I doon't think so. Again, I am so disappointed. I would have returned the product and chosen another had we not been in a lock down situation the country is in at the moment,

Rated 1 out of 5 by from 24hrs and not dry also thin watery and of no use. 24hrs and not dry, thin watery with no coverage on new wood. No use how can you sell such a poor product. WE went for Valspar as we love the emulsion paints but this is RUBISH!

Rated 1 out of 5 by from Thin, translucent terrible product I bought this some months ago now to undercoat and prime all the woodwork in my bedroom. Used it today and now wishing I hadn't finished the first coat. Its watery and translucent,its supposed to be white. I'm now hoping it drys reasonably (supposed to take 16 hours) so I can overcoat it with something else that can do a better job. After reading some of the other issues with this paint (after using it) I'm now dreading what mess its going to create trying to fix it.

Rated 1 out of 5 by from Terrible stuff - not worth the money We bought a 1 litre tin of white Primer Undercoat fro B & Q on the 2nd November costing £16. We sanded down our starircase, cleaned it and painted it, and 24 hours later it is sticky and hasn't covered the base coloures despite stirring it really well. It's a disaster as we have the carpet fitters coming in 3 days and the staircase isnowhere near ready.

Rated 1 out of 5 by from Poor coverage. I bought this product today and has a gloss finish and has very poor coverage and it also doesn’t hide marks, would need multiple coats to cover, paint is very thin for a undercoat primer and will require sanding and I will use a better product.
