Rithvik, Yes, people do use duco paint on HDHMR surface directly and it is indeed a good smooth surface for Duco. Having said that, a disclaimer is that we don't use HDHMR on our projects due to reservations on its longevity. Thanks, Nitin Cornerstone Designs Bangalore

Djhamu, why wouldn't it be fair enough a question ? The reasons of measurement differences could be many: 1 - Approximates: Eg. 10'4" Could be be considered as 11' and 10.5" by two different people. 2 - Work Approach : In a ABC triangle one has an option of going directly from A-C or from A - B and then B - C. Depending upon which route they take their measurements will be different. 3 - Misunderstood/missed requirements: When you say I need painting, some one will consider just painting while another one will include 2 coats of putty one of primer and then paint. Difference! 4 - Taking measurements lightly : Some folks know just by previous experience that a 2 BHK home painting would cost them say X and they give a rough measurements which will differ from the one taken by some one more methodical with measurements. The reasons of price differences is like any other service say a Doctor. Skill, Experience, Demand and competition are some of the economic factor that help them decide market rates. It doesn't mean the costliest one is best or cheapest one is not good. Recommendation: It's good to be involved in the process but too much of intervention by a new cook surely spoils the broth :). When I go to a Doctor I don't ask him how he knows which medicine is best for me or how much I should take :) likewise trust your professional here (unless you have a strong reason of not trusting her) Best way to approach would be to hire a trusted consultant, get your 2D- 3D drawings, measurements, product and material specifications, in black and white . Use this detail sheet to get a quote from different vendors. For example with drawings in your hand you already know that your wall is 9'1 X 15' measurement ask a quote with details like how many quotes of putty/ primer and sanding of which brand are required. It shall cover most of the differences above. 3 tips : : I have personally seen that people who 'know too much' are very easily duped. They fall quickly for the 'ego' trap. : Trust the people who have done good job in past with your friends and family, search around , get involved but not too much. Genuine reviews are there because people have been happy.. : Finally, don't fall for sweet talks :D Some one is 'cheaper' for a reason. Most of the jobs you mentioned is measured either in per/sqft or lump-sum basis. Thanks, Nitin Cornerstone Designs, Bangalore.

Hi, Duco is an NC lacquer. Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, and flash string) is a highly flammable compound formed by nitratingcellulose through exposure to nitric acid or another powerful nitrating agent. Polyurethane coatings are considered polymers. They can be very hard and strong, providing exceptional wear resistance. They can also be more soft and ductile, so that the base material is allowed to stretch without destroying the coating. Polyurethane coatings are not flammable, so they can be used for some situations where combustion is occurring in the same environment. Care must be taken to limit the exposure of a polyurethane coating to ultraviolet light because it can cause the coating to degrade. With green standards fast becoming the norm, PU is also available in water based variants that can be used to coat wood. They have a comparable performance to Solvent based PUs and are much easier to apply. They don't require elaborate spray equipment and also do not pose a health hazard as they can be brushed on. PU polish is relatively safe polish with petroleum based solvents. The water based polish has fewer volatile organic compounds. While 2-part PU polish is free from volatile organic compounds.

It depends on the overall mood you want to achieve. You can tile the whole place based on your preference or maybe tile the common areas to make it more cost effective. Wood flooring would also add some variety.
